August 1, 2025 by Maude Gauthier

Are you planning a home extension? If so, choosing the right foundation system is critical. Don’t make this decision lightly.

Helical piles, also known as screw piles, may not be the first solution coming to your mind. Concrete foundations are still very popular. But helical piles have emerged as an increasingly popular and sophisticated foundation option for home extensions.

However, you need to consider your options carefully before making a decision about any foundation system. Helical piles for home extensions come with their own set of considerations. Understanding the costs, and technical requirements, and installation process is essential.

Keep reading to get detailed information about helical piles for home extensions. Once you’ve learned all the facts, you’ll be able to make confident decisions about your home extension foundation.

Are Helical Piles Good for Home Extensions?

Yes, helical piles are great for most home extensions projects. If you don’t want to build a basement, screw piles are the perfect choice.

How do they work? Screw piles transfer structural loads through helical-shaped steel plates to stable bearing strata deep in the ground.

To get the durable foundation your home extension deserves, you’ll need proper planning and professional implementation of the helical piles.

Helical piles are specifically well-suited for additions because they can be installed close to existing foundations without causing:

Moreover, construction can proceed immediately after installing the piles. Unlike conventional concrete foundations that require extensive excavation and weeks of curing time, helical piles will save you time. Indeed, the helical plates provide immediate load-bearing capacity. The installation process also involves minimal site disturbance, which means your landscaping will remain intact.

In Quebec and elsewhere in Canada, screw piles are an excellent choice for:

Freeze-thaw cycles: deep installation below the frost line eliminates frost heaving concerns.
Poor soil conditions: the piles' size can be adapted for sand, clay, rock, and more.
Tight construction timelines.
An environmentally-friendly foundation.

What Are the Recommended Specifications for Home Extension Screw Piles?

From the 4-feet black steel screw piles found in your local hardware store to the specialized high-grade galvanized ones, there are a variety of helical piles available on the market.

For home additions specifically, be careful to buy high-quality products only. Black steel or painted steel can rust, jeopardizing your home extension, for instance.

Contact professionals to get an accurate estimate of the specifications for your project. The exact specifications depend on structural loads and soil conditions. This means that an engineer should visit the site and run a geotechnical analysis to determine the appropriate technical specifications.

Shaft specifications typically include:

A diameter of 2⅞ to 3½ inches for residential extensions.
Wall thickness of 0.276 inches at the minimum for structural grade.
Steel grade: CSA G40.21 Grade 350W or ASTM A572 Grade 50.
Hot-dip galvanization is recommended to avoid corrosion and preserve the piles’ lifespan.

Helical plate specifications typically include:

A diameter of 8, 10, 12, or 14 inches for the plates, depending on soil conditions and load-bearing capacity needed. Engineers can also recommend a combination of sizes when double-helix configuration is needed.
Minimum thickness of ½ inch.
Configuration: Single, double, or triple helix depending on soil conditions.

Length considerations:

How Many Screw Piles Do You Need to Install for a Home Addition?

The helical pile system evenly distributes the load between each pile. Some soils require installing the piles closer to each other.

Therefore, the quantity of piles needed depends on load calculations, adapted for each type of soil. Load calculations are complex. They typically include:

Typical spacing of the piles goes from 8 to 12 feet for interior supports to 6 to 8 feet for perimeter supports.

For example, common home additions sizes require 6 to 16 piles:

It is mandatory to hire professionals to determine how many piles your foundation needs.

Indeed, Quebec’s Construction Code mandates professional engineering for foundation design.

Therefore, a structural engineer must perform load calculations and soil analysis.

How Much Does a Home Extension on Helical Piles Cost in Quebec ?

Pricing varies a lot according to the number of piles needed, site specifications (for example, if it is difficult to access), and the company you hire.

Current Quebec pricing is approximately the following:

Moreover, taxes of close to 15% apply to all materials and services.

As a result, you can expect the total cost of your home extension to be as follows:

What factors can affect these estimates and change the total cost? A series of factors can complicate the project and add additional costs:

What Is the Lifespan of Helical Piles for Home Extensions?

You may be wondering if your helical piles for home extensions will last as long as a concrete foundation. This is an important question. High-quality piles can last as long, and often longer, than concrete foundations. Most manufacturers provide 25-50 year warranties with proper installation, but high-quality piles can last much longer.

What factors can affect the longevity of your helical piles foundation? These factors include:

Soil corrosivity: pH levels, chloride content, moisture.
Coating integrity: Quality of galvanizing.
Installation: Proper professional installation prevents damage.
Maintenance: Exposed portions require periodic inspection.
Salt exposure: Home extensions near roadways may accelerate corrosion.
Groundwater: High water tables may also affect corrosion rates.

What Are the Advantages and Disadvantages of Building a Home Addition on Helical Piles?

If you do things right, helical piles for home extensions are a good long-term investment.

This foundation system offers many advantages over traditional concrete footings. The piles’ ability to provide immediate load-bearing capacity, all the while maintaining minimal site disturbance, makes them particularly interesting for most construction projects in Quebec.

Worried about the costs? The upfront cost may be higher, but screw piles often prove cost-effective when considering there is no need for excavation, you save a lot of time, and you eliminate most frost-related issues.

The main advantages include:

Immediate load-bearing capacity: Build your structure right after the installation ends. There is no curing time.
Quick installation: It takes only 1-2 days.
All-weather installation and frost-proof: Installed below frost line eliminates heaving. Installation is possible even in winter.

Why Choose Screw Piles to Install Your Fence?

July 28, 2025 by Maude Gauthier

You would like to make your yard more private, but you don’t know how to choose between different types of fences? When you decide to border your yard, you may pick a wood fence, a chain-link fence, vinyl or even iron, but what about the foundation?

You have to think about what kind of foundation would be best for your fence. Concrete is not the only option available. Screw piles are actually a fast and safe way to start the installation of any type of fence.

The foundation is crucial for building a sturdy fence that will remain stable over time.

What Are Screw Piles For Fences?

Screw piles for fences are pretty much like any other screw pile. Length, diameter, and other specificities vary according to the load-bearing capacity you need for your fence. There are different sized piles for different applications.

Screw piles are also called helical piles. They are like a very long and large steel screw made of:

This design helps disperse the weight of the load into the soil. Helical piles can be used for a wide variety of applications including fence posts. They don’t require the use of concrete. The back pressure built up while screwing them into the ground holds them.

How Are Screw Piles For Fences Installed?

Installing screw piles is not usually a DIY project. The reason is simple: special equipment is needed to drive the screw into the ground.

Most certified installers use a drive motor head attached to a mini excavator. Sometimes, a regular excavator or a skid steer is preferable. As the pile is screwed into the ground, it creates back pressure. The machine can measure torque, and as soon as the proper torque is reached, the installers stop driving the screw into the ground. The depth of the installation will vary according to the type of soil.

Concrete VS Screw Piles For Fences

Installing helical piles is faster and more environmentally friendly than any concrete foundation. The equipment is compact and there is no need for digging, which means there is almost no disturbance of the soil. In other words, concrete foundations necessitate excavation, while screw piles do not.

Screw piles for fences also have immediate load-bearing capacity. You can install your fence right after and do not need to wait a few days. Concrete-supported fence posts take more time to cure.

Moreover, screw piles can be installed in almost any weather. You don’t have to wait for spring to show up! Concrete-supported posts need a temperature above 5°C. Screw piles for fences can be installed much earlier in the season, and sometimes even in the winter.

Do you have sloped terrain, poor drainage or any other difficult soil? Sometimes, it’s simply impossible to pour concrete. But helical piles are much more adaptable and can be installed in a wide range of soils! Using helical piles, you are able to build a fence in difficult areas.

What Are the Benefits of Screw Piles For Different Types of Fences?

Are screw piles appropriate for any type of fence? Yes, but the requirements may vary. Here’s a comprehensive breakdown for different fence types:

-	Wood fence	Vinyl fence	Iron fence	Chain-link fence
Affordability of the fence	Affordable	Higher material costs	Higher costs	Most economical fence option
Screw Pile Type	Standard 2.875 inches diameter	Standard 2.875 inches diameter	May require larger diameter piles (3 to 4 inches) for heavier iron fencing	Standard 2.875 inches diameter
Benefits	Screw piles prevent rot at ground level	Vinyl and screw piles won't corrode or rot	Metal can withstand extreme weather conditions (such as high winds)	Excellent resistance to fence tension forces

Typically, screw piles for fences have a diameter of 2.875 inches. Most of them are 6 feet long, but you can add an extension if deeper installation is needed. It is better to choose piles made of hot-galvanized steel for corrosion resistance, but there are a variety of steel grades to choose from. To make sure your fence is stable and can resist horizontal forces, don’t plan for more than 6 feet between each pile.

Privacy fences have higher requirements. They are typically made of wood or vinyl and because they catch more wind, they require stronger foundations. Screw piles with a larger diameter (3 to 4 inches) are recommended due to wind load. Also, if the panels are very tall, closer spacing (4 to 5 feet instead of 6 feet) may be needed.

Wood Fence

Choose a wood fence if you want to customize it: height, width, style, and color can be customized according to your taste. Wood is also affordable and environmentally friendly.

Vinyl Fence

If you seek complete privacy, vinyl fences are excellent. Vinyl is about five times stronger than wood, and no maintenance is needed. It won't blister, rot, or peel. Both vinyl and galvanized steel screw piles resist weathering, which makes it an excellent choice.

Iron Fence

Iron will give your yard an exquisite look. You can also get ornamental iron, which is in fact steel instead of iron. Metal fencing will last for decades, and it also works great if your property has an uneven grade.

Chain-Link Fence

A chain-link fence is the most economical option. Your fence will be resistant, and you can always add slats if you want more privacy.

Screw Piles For Fences Installation: DIY or Hire Professionals?

Helical piles can be bought in almost any hardware store. However, this does not mean that you should go ahead and install them yourself. An improperly installed helical pile can put your structure at risk of collapsing.

Piles sold in stores usually support a load of 2,500 to 4,000 pounds depending on soil type. You can get 6 feet long piles for about $50, and extensions for about $15. They often use a baked powder coating finish instead of galvanised steel.

If you have no experience in screw piles installation, you should hire professionals. Otherwise, you will have to rent special equipment to screw the piles and measure torque.

Screw piles for fences are relatively easy for a professional to install, because they have training and experience in this type of installation.

Installing Screw Piles on a Slope: Challenges and Solutions

July 23, 2025 by Maude Gauthier

Building your own home or chalet in a mountainous region is a dream come true. But there is one obvious obstacle: a sloped site. Will the building settle over time? Choosing the appropriate foundation solution will prevent this problem.

Wondering if you should go with a concrete foundation or screw piles for sloped terrain? Screw piles are very efficient, economical and adaptable to all types of terrain.

Always hire experts to install screw piles, especially if your land presents specific challenges such as slopes.

What Are The Construction Challenges Affecting Sloped Areas?

Most construction projects involving a house, garage or other big structure require a foundation. How to make sure it is solid and secure?

Helical piles present distinct advantages:

Why Choose Screw Piles For A Sloped Terrain?

Screw pile systems are designed by engineers. They take into account compression, tension and lateral forces that will be placed on the piles, which leads to the choice of appropriate shaft diameter and helix diameter, as well as number of piles needed. More specifically:

In the end, the array serves as a complete structural unit to support the overall load.

Screw Piles For Sloped Terrain: Lateral Stability Concerns

Construction on sloped terrain needs to factor in lateral stability concerns. Unlike flat ground construction, sloped surfaces introduce horizontal (lateral) forces. The steeper the slope, the more pronounced this lateral earth pressure becomes. Different parts of the foundation system may experience varying loads.

Moreover, slopes are inherently less stable than level ground because gravitational forces want to move the soil downhill. Traditional foundation methods were not designed to handle these conditions. On a slope, they often require expensive soil stabilization measures before construction can begin.

But helical piles can get the job done much faster! That being said, careful engineering of the pile system is absolutely necessary to ensure uniform support.

Do You Need Piles With A Double Helix Configuration?

Double helix configurations represent an advanced engineering solution for sloped construction. The deeper helix provides primary bearing support and the upper one helps resist uplift forces.

This type of screw pile has two helical plates spaced along the shaft. The larger helix is usually positioned at the bottom and there is a smaller one higher up. Why two helical plates?

Engineers will precisely calculate the spacing between the helical plates based on soil conditions and structural requirements.

Should You Install Battered Piles?

Battered piles are piles installed at strategic angles rather than vertically. They are another solution to manage lateral forces on sloped construction sites.

A geotechnical analysis can determine the appropriate angle and positioning to ensure optimal resistance to sliding. Typically, angles range from 15 to 30 degrees from vertical. The piles are positioned to directly counteract the anticipated lateral forces.

The main advantages of using battered piles are:

Installation requires specialized equipment:

Drilling has to be done at precise angles to insert the piles at the right angle, taking into account different soil layers, to achieve the intended load distribution.
Even small deviations from the design angle can impact resistance to lateral forces.
Connection details such as custom-welded brackets need to transfer loads efficiently between the vertical and angled piles. Professional welding is critical to the foundation's stability.

Is Angled Bracing Necessary?

Above-ground structural bracing systems provide an additional layer of lateral stability. They act as a complement to the double helix configuration and battered piles. They help reduce the lateral pressures on the foundation system.

What is angled bracing?

Once finished, you obtain a triangulated framework.

However, bracing can have a negative impact on your home’s aesthetic. To counteract this problem, you might ask your contractor to use cable bracing systems or position braces to frame openings (rather than obstruct them).

Screw Piles For Sloped Terrain: How Deep Do The Piles Need to Go?

Screw piles can be driven very deep into the ground, for example over 20 feet deep on a sloped terrain that requires it. If needed, you can add extensions to make the shaft longer.

By measuring torque on site, professionals make sure each pile will go deep enough so that the helix is locked into competent soil. They measure the torque off the drill head from the installation equipment, which is then converted to a bearing capacity.

This means helical piles can be installed much deeper than concrete foundations.

What To Do Before Installing Screw Piles On a Sloped Terrain?

Even if screw piles are a great solution, don’t go in headfirst. Before taking the plunge, follow expert advice.

Consult professionals:

Perform a soil study:

How Long Do Helical Piles Last in Canada?

July 22, 2025 by Maude Gauthier

People are concerned about helical pile durability, wondering if the upfront cost is worth it. Helical piles are becoming more widely used to support home extensions, cottages, fences, sheds, walkways, and public structures throughout Canada. But before going ahead with the construction, consumers often wonder how long the piles will last.

Professionally manufactured and installed screw piles are a versatile foundation solution for a variety of soil conditions: sand, clay, rock, flood-prone regions and more. They can be installed quickly and they provide a low-impact environmentally friendly alternative to traditional concrete foundations.

Expect Helical Piles to Last Over 100 Years

Rest assured, once your screw piles are installed, they will last a very long time. Generally speaking, they can last 100 to 150 years, sometimes more.

Because they last this long, helical piles are a cost-effective and environmentally friendly solution as well.

However, it’s important to note that not all screw piles are the same. Their durability can be influenced by a range of factors.

What Factors Impact Helical Piles Durability?

The following factors assume that you buy helical piles that are manufactured and installed by experts. Structures built on helical piles should always bear an engineer’s compliance certification. Moreover, you should hire a professional to install helical piles, because it needs to be done using specialized tools and precise torque measurements.

Once quality screw piles are installed by professionals, why do some last longer than others? There are a number of factors to take into account when trying to understand the longevity of the piles.

Helical Piles Durability: The Impact of Material Quality

Unsurprisingly, the quality of the materials used in screw pile production impacts how long they will last. Indeed, helical piles are not all the same. Some are galvanized or coated to resist corrosion, for instance, or use sacrificial material to make them thicker.

Key durability factors in Canada include:

Several significant industry-wide manufacturing problems that have been documented: Steel sometimes tested below the code-required strength, and manufacturers used paint and other cheap coatings instead of hot dip galvanizing.

Make sure you hire a contractor that uses hot-dip galvanized steel and follows regulations. Here’s an overview of steel quality:

Best: Hot-Dip Galvanized High-Strength Steel

Most helical piles are composed of rust-resistant galvanized steel.

Good for above-ground applications: Weathering Steel

Moderate quality: Painted/Powder Coated Steel

Moderate quality: Extra thickness with Sacrificial Material

Avoid Black Steel

Many durability issues stem from the use of inferior materials such as paint instead of hot-dip galvanizing and substandard steel grades.

Don’t try to save money by hiring a contractor that suggests lower-quality piles, because it will reduce the expected lifespan of your foundation.

Mistakes in Load-Bearing Capacity Calculation

As soon as they are installed (properly), helical piles offer instant load-bearing capacities. They can accommodate hundreds of tons for all types of projects.

What happens if the contractor miscalculates the load? Does it cause helical piles to wear down more quickly? Yes, and here’s how:

Under these conditions, screw piles may not be able to withstand heavy stress.

However, if you install the proper screw piles correctly, they should last at least as long as the warranty.

Helical Piles Durability: Soil Conditions

Across Canada, we find a variety of soils. The soil conditions of the installation site also have an impact on screw piles.

However, in very stable soil conditions, your screw piles could last much longer than 150 years!

Key factors affecting longevity include:

Canadian soil types can be described as follows:

Podzolic soils

This well-drained, acidic, and sandy textured soil is usually good for helical piles. Its good natural drainage reduces corrosion risk, although high acidic conditions may produce the opposite effect. Screw piles are easy to install in this type of soil.

Clay-rich soils

Clay can retain moisture, increasing corrosion potential for helical piles. You may have to get longer piles to reach the deep stable layers of the soil. This way, it will provide a good bearing capacity for pile support.

Chernozemic soils

The dark, organic-rich, well-structured soil of the Prairies is excellent for screw piles. Its lower moisture content reduces corrosion and provides stable foundation conditions.

Rocky/Dense soils

The Canadian Shield and mountainous regions are mostly rocky. These very dense soils can pose problems when installing standard helical piles. However, they provide excellent long-term stability once installed. There is a very low corrosion risk due to good drainage. Your contractor may need to use carbide tips designed to break through rocky soil conditions.

Permafrost soils

Located in the arctic regions and northern territories, permafrost soils can pose problems when installing standard helical piles. However, they offer good long-term stability once installed. Installation often requires pre-drilling pilot holes.

The most favorable for longevity are rocky and sandy soils. They naturally provide excellent drainage and minimal corrosion of the piles.

Cryosols slow corrosion because of the cold, but installation is way more difficult. Very acidic or clay-rich soils also pose some problems such as moisture retention, which lowers the piles’ longevity.

You have no idea what type of soil you have? Have it tested before ordering screw piles. Many contractors have an engineering department that can take care of this for you. Once you have an answer, they can take additional precautions.

Beware of Ground Movement

Ground movement can also affect the lifespan of helical piles. It happens in specific locations. In such areas, unstable soil can break down helical piles faster.

Be careful and ask for professional advice if you live in:

Is the Durability of Helical Piles Better than That of Other Foundations?

In good soil conditions, helical piles benefit from excellent durability. Look at the table below to see how they compare to other foundational solutions.

Foundation Material	Lifespan
Helical Piles	About 150 years
Concrete Slab	50-100 years
ICF Blocks	Up to 75 years

With a potential lifespan of up to 150 years, helical piles outperform traditional foundations.

How To Make Screw Piles Last Longer?

The moment when you choose your contractor is crucial. It’s important to check their credentials. Also, you should verify who manufactures the piles they sell. These verifications will help you get the best piles for the job. Basically, you should:

Always hire professionals with a long experience in installing screw piles.
Choose the right type of piles for the structure you want to build.
Make sure the contractor performs relevant load tests.
Once they are installed, inspect your screw piles regularly.
If any problems arise, address them as soon as possible.

How Screw Piles Adapt to Clay Soil Conditions

July 15, 2025 by Maude Gauthier

Clay soil has a reputation for being tricky to build on due to its high degree of moisture and changes across seasonal fluctuations. Are helical piles a good foundation solution to use in clay?

Helical piles, also known as screw piles, can be effectively used in a variety of soil conditions including clay soil. Their design can be adapted to anchor firmly in cohesive clay, for instance.

Find out when and how screw piles are suitable for clay soil. Build decks, sheds, garages, home extensions and more on a stable foundation.

Is It a Good Idea to Use Screw Piles For Clay Soil?

You may have heard that screw piles can be installed in any type of soil, from loose sand to dense clay.

The techniques may vary from one type of soil to another, but helical piles are especially versatile. That explains why they have become popular as building foundations.

In fact, the cohesive nature of clay offers better lateral stability for helical piles.

What Are the Characteristics of Clay Soil?

Let’s try to understand what makes clay soil tricky for concrete foundations and why screw piles are a good fit in this type of soil.

Clay is often dense and cohesive. Because it expands and contracts easily (for example when water penetrates the soil), it can cause shifting in traditional concrete foundations. This does not happen with helical piles when they are installed deeper into the ground.

Loam is also partly made of clay. It is a mixture of sand, silt, and clay. In this mixture, clay does not cause construction challenges and loam is generally considered a well-draining and stable soil.

How Do Helical Piles Perform in Clay Soil?

Screw piles are particularly well-suited for clay soil. Here’s why:

Clay is cohesive, which provides excellent grip for the helical blades of the screw pile as well as lateral stability.
Screw piles maintain their structural integrity even when the soil shifts, for instance when moisture levels cause the clay to expand or contract.
Screw piles are made from high-quality steel and can withstand extreme conditions.
Helical piles cause less soil disturbance during installation. This reduces the risk of ground movement post-installation.
Installation is fast and more cost-effective than traditional methods, especially in challenging soil conditions.
Screw piles can be driven deeper to reach more stable soil layers, ensuring a secure foundation.
Once the helical piles are installed, you can start building right away because they have immediate load bearing capacity.

What Type of Screw Piles Do You Need For Clay Soil?

There isn’t one type of screw pile that is specifically designed for clay soil. It’s important to always get an engineer to assess the soil conditions and determine the types of piles you need – which also depends on the load of the structure you’re building, for instance.

Screw pile specifications will account for clay’s unique properties. To install screw piles in clay you typically need to consider:

Pile shaft diameter

Helix configuration

Multiple helixes should be spaced 2 to 3 times the helix diameter apart.
A diameter of typically 8 to 16 inches (depending on loads) is recommended.
Smaller pitch (steeper angle) helixes work better in clay than in sand.
The lead helix should be the largest, with progressively smaller helixes above.

Steel specifications

Screw Piles for Clay Soil: What Is the Proper Installation Depth?

Helical piles are typically installed deep in the ground, below the soil’s frost zone. This simple attribute protects your foundation from ground movement. Moreover, clay soils can experience significant moisture-related volume changes in the top layers. In clay, screw piles are often installed deeper than in other soil types.

What depth should you achieve in clay soil? Typical depth ranges are as follows:

In clay soil, the piles must penetrate through any soft or unstable layers to reach deeper, more stable layers. Stable layers of clay can be described as follows:

What Are the Main Installation Considerations for Screw Piles in Clay Soil?

In any type of soil, a thorough soil analysis must be conducted before installation. It is crucial to determine the appropriate pile size, helix diameter, and depth for optimal performance.

During the installation process, torque needs to be carefully monitored to ensure proper anchoring. Installation continues until the required torque is achieved. In clay, this is less reliable than in other soils types. For more security, load testing is often recommended. Therefore, the contractor will stop when torque is reached, regardless of planned depth. They can dig deeper if needed.

By following these best practices for installation, screw piles can provide a reliable foundation solution in clay soil.

When To Use Screw Piles In Clay Soil?

What Can You Build On a Helical Pile Foundation?

Decks, patios, home additions, retaining walls – you can build anything on helical piles! What makes them so great is that they are suitable for any type of structure and can be installed in almost any weather condition.

The wide variety of structures you can build on helical piles in Winnipeg might surprise you. It includes:

How Do Helical Piles Work?

Here’s how the process of installing helical piles works, from supply to installation:

Plan ahead

First, you need to determine if your soil presents some challenges with the help of a geotechnical engineer. Is it made of clay or sand? How deep will the piles need to be to reach the solid layer in the soil?

If you hire a contractor who has an engineering department, he will conduct a site visit to evaluate soil composition and depth to stable strata as well as load-bearing requirements. His engineers will design the foundation plan based on this information. You need this engineer-stamped design in order to get the permit from the City of Winnipeg.

Choose the right pile type

You have to get some knowledge about your soil before you order the piles for a very simple reason: the type of piles needed changes according to soil type. The dimensions of the piles will also vary according to how much weight the pile must support. You should get CCMC-approved piles.

Proceed to installation

Installers with a lot of experience in similar projects and the right equipment can complete the installation in just a few hours. They will start by marking the site. Then, they will use a hydraulic drive head mounted on a mini-excavator or skid steer to rotate the pile into the ground. If the load-bearing layer is deep, shaft extensions are bolted on. Once the work is completed, a bracket or cap plate will be attached to the pile head so you can build your structure on top.

Simply wait for the installers to be done and start building your patio (or anything else)!

Benefits of a Helical Pile Foundation

There are multiple benefits to a helical pile foundation, especially in difficult soil conditions, if you’re looking for an environmentally-friendly solution, or if you are in a rush. With screw piles, you will benefit from:

How Much Does It Cost to Install Helical Piles in Montreal?

May 21, 2025 by Maude Gauthier

Helical screw piles are a very useful technology when it comes to supporting structures in Montreal. They can be installed even when it’s cold outside, and they fit into tight spaces, which is especially useful in highly populated neighbourhoods.

But are helical piles cheap? No, high-quality piles are not cheap, but they are certainly worth your money.

Once you determine whether your construction project can be supported by helical piles, you can benefit from their many advantages and start building much faster than you would have with a concrete foundation.

What Is a Helical Pile Exactly?

A helical pile is also known as a helical pier or screw pile. It is a screw-shaped foundation solution used to support structures. They can be especially useful where soil conditions are not suitable for traditional shallow concrete foundations.

The piles consist of a steel shaft with one or more plates welded to it. Just like a giant screw, they are screwed into the ground using hydraulic machinery. They can reach a depth of 20 feet sometimes, but 8 feet are usually sufficient. The goal is to reach where the soil can adequately support the load, often reaching stable subsoil layers. This way, the piles transfer building loads to deeper, more stable soil or bedrock.

What Can Helical Piles Be Used For in Montreal?

In most construction projects, helical piles can replace concrete foundations. They can also help restore an existing foundation that is sinking, for instance. Here are 3 major uses for screw piles in Montreal:

Are screw piles suitable for any type of soil?

Yes, screw piles work in most soil types, including clay, sand, and fill, which are common in Montreal. A soil test can confirm suitability for your project.

How To Know If Your Foundation Is Sinking?

If your foundation is sinking or sagging, don’t wait, ask immediately for helical piles quotes to help restore the building’s structure. There are several visible and invisible signs to watch for. Here’s a breakdown of the most common warning signs, even the subtle ones. Since homes in areas like Montreal have to live with freeze-thaw cycles, clay soils, and heavy moisture, be on the lookout for these signs:

Cracks in exterior foundation walls (especially near corners or window/door openings).
Uneven floors, such as a noticeable slope when walking across a room.
Cracks in exterior siding.
Gaps around doors and windows, where there were none before.
Cracks in drywall, especially if they continue to grow over time.
Sticking doors or windows.
Bowing or sagging basement walls.
Water infiltration in the basement, or leaks, moisture.
Water pooling near the perimeter of the house.
Erosion, sinking ground, or gaps between the soil and the foundation wall.

Every house usually has a few small cracks. But if they are wider than 1/4 inch, keep increasing, or if you notice multiple signs occurring at once, it’s very likely foundation settlement is to blame. In this case, it’s time to get quotes for helical pile underpinning!

The Advantages of Screw Piles

There are many reasons to buy helical piles for any kind of foundation:

No excavation needed (saving time and preserving the environment).
Quick installation.
Load-bearing capacity is immediate, which means you can start construction right away.
Fits in tight spaces.
Adapted to good and poor soil conditions.

How long does it take to install a screw pile foundation?

Most residential screw pile foundations can be installed in one day, depending on the number of piles and site conditions. It is a clear advantage of screw piles over concrete!

Are screw piles a good option for uneven ground?

Helical piles can be installed at variable depths, making them ideal for sloped or uneven ground without major excavation.

To get the most for your screw piles installation, make sure to hire a company that has its own engineering department and offers good warranties.

Which Helical Piles Are Worth Your Money?

In Montreal, helical piles are widely available for both residential and commercial construction, and they come in various types. Smaller helical piles sold in hardware stores are usually cheaper than those offered by professionals, but they are not as good.

Here’s a breakdown of the helical piles you can find:

Material Types

Galvanized steel helical piles are the most commonly used in residential projects such as decks, patios and small additions. They are corrosion-resistant and have a lifespan of 50+ years in most environments. They offer the best value for money.

Bare steel piles are less expensive upfront, but more prone to rust over time, especially outside. They can be used in interior/controlled environments.

Hot-dip galvanized steel is a higher-end version of galvanized steel: piles are dipped in molten zinc for thicker, more uniform coating. This type of pile is suitable for high-humidity, commercial or public infrastructure projects.

Stainless steel is only used in specialty or high-value projects. It is much more resistant, but very expensive and usually an overkill for residential jobs!

Shaft Types

There are basically two types of shaft. The round shaft is very common and typically used in light residential applications. It makes the piles easier to install in soft or clay-heavy soils.

A square shaft is stronger in tension, often used for underpinning or lifting existing foundations.

Helix Configuration

Helical piles can have a single or multiple helices of 8 to 14 inches. Single-helix piles are used in light structures or when soil resistance is shallow. Piles with 2 to 4 helices are suitable for higher load-bearing capacity or deeper installations.

If you’re doing a residential job in Montreal, a galvanized steel round shaft pile with a single or double helix will cover 90% of typical needs.

Common Brands and Suppliers in Montreal

There are a few excellent and reliable suppliers in Montreal, among which you will find:

Choosing the right one for you depends on the type of structure you want to build and factors such as soil conditions.

Is there a warranty on the installation of screw piles?

Professionals typically offer a 25-year warranty on materials and 1 to 5 years on installation. This information should figure in your quotes.

Are installers familiar with the local building regulations in Montreal?

Certified installers in Montreal must follow CCMC-approved standards and are typically well-versed in local codes and permit requirements. Always confirm this during the quote.

What Will Your Helical Pile Contractor Cost in Montreal?

High-quality helical piles require engineering and precision in their design and manufacture. They are a critical component of the structure.

You should at least check that the piles you are buying are CCMC-approved. Moreover, make sure you work with an honest contractor who will source excellent materials. For instance, look at their reviews and talk to their customers before you sign a contract.

Illustration Of The Costs Of A Home Addition

Say you need a helical pile foundation for a home addition in Montreal. The size will be 240 square feet in moderate soil conditions.

The company you picked bundles engineering and installation for a better price. But you still have to pay for the construction permit required by the city of Montreal, a soil test and the setup. Look at the table below for a breakdown of the costs you can expect to pay.

Cost Breakdown
Total	$6,000
Number of piles	10
Cost of 1 pile, installed	$450
Mobilization, soil test, permit drawings	$1,500

Important Cost Factors for a Helical Pile Foundation in Montreal

The quotes you received are different from the illustration above? Prices vary from one contractor to another, but also according to a series of external factors. In Montreal, the most important cost factors are:

Soil conditions: soft clay often requires deeper piles; rocky or dense soils may increase installation time and equipment wear.
Load requirements.
Quality of materials.
Number of piles required, determined by structure size, weight, and load distribution.

Are Grants Available To Help Cover The Costs Of Helical Piles in Montreal?

If you are planning to renovate your home because it has become dangerous for its inhabitants or need an addition, you may be eligible for a grant from the Société d’habitation du Québec, administered in conjunction with the City of Montreal. The program is called Rénovation Québec and helps homeowners dealing with damaged foundations, among other things.

The City of Montreal also put in place a program called Stabilization of Residential Building Foundations Program. Financial aid is available for the installation of helical piles as well as for related work like the consolidation and waterproofing of foundations, excavation and backfilling.

Get Helical Piles To Build a New Structure Or Stabilize An Older Home in Montreal

Helical Piles Price in Toronto | Cost and Quotes in 2025

April 30, 2025 by Maude Gauthier

As the Greater Toronto Area continues to grow, the demand for high-quality foundations is growing. A reliable base is of utmost importance, especially given the current housing market conditions. Whether you’re building a new deck, underpinning a home, or supporting a commercial structure, helical piles offer a strong foundation and many advantages over concrete.

How much do helical piles cost in Toronto in 2025? What should you expect when requesting a quote?

Screw piles remain relatively unknown, despite offering many advantages for homeowners.

What Are Helical Piles?

Helical piles, also known as screw piles, are just like giant screws! They are long steel shafts with helical plates at the bottom. They are drilled into the ground using specialized machinery, such as an excavator and hydraulic drive head.

Helical piles are perfect to support new construction or stabilize existing structures. They can be dug really deep into the ground, sometimes deeper than 10 feet, in order to reach load-bearing soil below the frost line. This helps the house, garage or other construction to stay stable across all seasons.

This system is especially appreciated for its speed of installation and adaptability to different soil conditions. Here’s a full list of the advantages of screw piles:

Quick installation (most residential projects are done in only 1 day; there’s no curing time like concrete)
Minimal or no excavation, which is good for the environment
Can be installed year-round, even in winter
Works well in poor soil conditions (such as clay or rocky soil)
Lasts for 75 to 100 years, with corrosion protection in place
Removable and reusable in some cases

These benefits have made helical piles increasingly popular in both residential and commercial projects throughout Toronto and everywhere else in Canada.

Wondering if your project is a good candidate for helical piles? They can be used for all types of structures, including decks, additions, garages, fences, and even large commercial buildings.

What Is the Cost of Helical Piles in Toronto?

In 2025, the average price of helical pile installation in Toronto ranges from:

Below is a table of the cost breakdown you can expect.

Item	Estimated Cost
Total per installed pile	$300–$700
Helical piles (material only)	$100–$250 per pile
Installation (labor + machinery)	$150–$350 per pile
Engineering or permits (if needed)	$100–$500

Prices are always subject to market conditions and can vary depending on demand. In order to lock in a price soon, ask for quotes from local entrepreneurs now.

Key Factors That Affect the Price of Helical Screw Piles

Helical screw piles prices can vary depending on several critical factors.

Soil Conditions

Soil type has a huge impact on cost. Toronto has a mix of clay, sand, and silty soils, and some neighborhoods near the lake have higher water tables or fill materials. The type of soil has a huge impact on the price of helical piles because it changes the number of piles and the length of the shaft needed. All of this also translates into increased labor time and the workers may need to use specialized (more expensive) equipment.

Load Requirements and Project Type

Helical piles that support a house are more expensive than those used for fences or small decks due to higher load requirements. A higher load may require larger diameter shafts or additional piles, increasing the total cost.

Moreover, while a standard pile may go down 10 to 15 feet, some projects require depths of 20+ feet to reach load-bearing soil. You may have to pay for extensions. This increases the material and labor cost.

That’s why the purpose of the piles matters and it’s the first question contractors are going to ask you:

Site Access and Equipment Needs

Urban lots in downtown Toronto can pose access issues for installation machinery. Often, there’s not enough space for standard excavators, for example if your backyard is tight or has limited entry points. Smaller machinery may be required, but it is more expensive. Otherwise, manual methods may be needed but then labor costs might skyrocket.

Permit and Engineering Costs

Depending on the project and specifically where you reside within the GTA, you may be required to get permits or stamped engineering drawings to install helical piles. Usually, you need a permit for structural additions or foundation work. However, for decks and small structures, it depends on size and height. Permits may add a couple hundred dollars to the total cost of the project.

How Many Piles Do You Need to Buy?

The number of piles needed depends on your project, including the load requirements depending on the structure’s size, weight, and layout. Here’s a quick estimate for common projects:

A small deck of 10 x 10 feet typically requires 4 piles. If these piles cost $300 each (installed), you’ll pay $1,200 for your new deck.
A terrace of 12 x 16 feet may require 5 to 6 piles.
Adding a sunroom or another room to your house may require 8 to 12 piles, sometimes more.
Foundation repairs are harder to assess but you can plan for at least 10 to 30 helical screw piles.

When you request a quote, contractors usually conduct a site visit. This helps them assess the number of screw piles needed. Alternatively, they can use engineering specifications to determine the correct number.

Helical Piles vs. Concrete Foundation: Price Comparison

At first glance, concrete footings may seem cheaper than helical piles. However, when factoring in excavation, forming, curing time, and inspection delays, helical piles often match or beat the price of concrete. And remember, no matter how much they cost, helical piles can be better for projects requiring speed or with difficult soil conditions.

The table below helps you compare helical piles to concrete. Please note that excavation costs are not included.

Project	Helical Piles	Concrete
Terrace 10 x 10 ft	$1,200 +	$2,500 +
Garage 12 x 22 ft	$5,000 +	$6,600 +
Shed 5 x 5 ft	$650 +	$625 +
Home addition	$5,000-$12,000	$4,900-$10,000

What to Look For When Receiving Quotes for Helical Piles?

In 2025, the Toronto market includes both specialized helical pile companies and general contractors offering installation as part of a larger service. When requesting quotes from helical pile contractors in Toronto, make sure the estimate includes:

Prices vary between contractors based on equipment, experience, and business models. You should not accept the first quote you get, whether you think it’s a good price or not. Getting multiple quotes helps you compare fairly. The cheapest bid may not include as much as another quote. Also, it never hurts to check Google reviews, Better Business Bureau (BBB) ratings, and ask for references before signing a contract.

Can I Install Helical Piles Myself?

No, you should not install helical piles yourself. Improper installation can lead to structural failure. Instead, look for companies that have a certification, offer in-house engineering, and provide proof of insurance or guarantees.

Helical piles are not a DIY project. Even small decks require precise torque settings and verification of load-bearing capacity!

Find Out About the Best Cost-Saving Tips

If you cannot install them yourself, how can you save money? There’s a few tips you should be aware of:

Plan in advance: Last-minute projects may cost more due to scheduling constraints.
Combine work: If your neighbour also needs to install helical piles, try to join forces and hire the same contractor.
Simplify access: Clear the way for machinery to reduce labor time.
Avoid peak season (late Spring and Summer): Off-season installs usually offer better pricing.

Helical Screw Piles Are Definitely Worth It! Get Your Quotes Now!

In Toronto, as in other Canadian cities, helical piles may cost more upfront than basic concrete footings. However, their durability, installation speed, and adaptability make them an excellent long-term investment.

Getting quotes early in the process is important because you will need time to compare services and prices, and choose YOUR contractor that offers peace of mind, a fast timeline, and a high-quality foundation for years to come.

Helical Pile Machine Rental in Ontario | Rates 2025

April 16, 2025 by Maude Gauthier

Helical piles are usually installed by highly skilled and trained workers, especially for larger projects. But what if you would like to install them yourself? It is possible to rent an excavator and hydraulic drive head in order to do the work yourself.

Many construction rental companies can help you get all the equipment you need to install helical piles for decks, docks, sheds, home foundations, and more.

Helical Pile Installation in Ontario: Can You Do It Yourself?

For small projects, you can buy helical piles at home improvement stores. These likely won’t dig very deep in the ground. They cost approximately $35 to $50 each and you may need to buy extensions. They can usually support up to 3,500 to 5,000 pounds, depending on the soil conditions.

If you buy them from a certified installer, helical piles can cost up to $500 each (sometimes more), including installation. These piles are much better than the ones found in home improvement stores.

Even for small projects, an engineer’s expertise is recommended. They will be able to tell you what is the correct depth and torque to aim for. For bigger projects, an engineer’s expertise is unavoidable and often required to get a construction permit. That being said, contractors and homeowners alike may need to rent equipment for all types of projects.

Do You Need a Permit to Install Helical Piles?

In Ontario, building permits are often required when structural elements like helical piles are used. This is the case for decks, additions, and small structures tied to the home. Municipalities typically classify helical piles as deep foundation elements. You’ll likely need to submit engineering drawings or torque test results. Your local building authority may require load-bearing verification. It’s a good idea to call them before starting work to make sure you are aware of all zoning rules or bylaws.

What Equipment Do You Need to Install Helical Piles?

Installing helical piles requires a combination of specialized and general construction equipment. Weight is required to resist the torque applied to a helical pile; the rental machine, such as a mini excavator, first serves as the foundation for installation. Equipped with a hydraulic pump, the machine will be able to manipulate, align, and locate the installation of a helical pile.

If you are not trained as an operator of such a machine, helical pile installation will prove difficult and you will likely face installation issues. To prevent such issues, hire specialized operators.

Core Equipment for Residential Installations

Mini-Excavators

Mini-excavators are a popular choice. That’s the machine experts usually use – you cannot go wrong with that one. They are the perfect choice when the torque required is less than 15,000 ft-lbs.

You will need a trailer to transport the equipment to the construction site. Mini-excavators can be moved on a 20 to 24 feet long equipment trailer.

Mini-excavators can be easily maneuvered in small spaces. Moreover, their metal or rubber tracks decrease ground pressures.

When renting a mini-excavator, always confirm with the rental company that:

Standard Excavators

When more torque is needed, you should rent a standard excavator. Also, their longer boom lengths translates into a higher boom height, allowing installation of sections up to 15 feet or longer.

However, because this machine is bigger, mobilisation costs will be higher. You will also need to make sure the site access is big enough.

Hydraulic Drive Head

The hydraulic drive head is what screws the helical piles into the ground by delivering high torque at low rotational speed. The excavator pumps pressurized hydraulic fluid into the drive head, the gears multiply torque and turn the output shaft, which is connected to the helical pile, while the mini-excavator pushes down. A hydraulic drive head allows precise installation with minimal soil disturbance, including load verification.

What Else Do You Need to Successfully Install Helical Piles?

It’s better not to do this alone. You will need the help of at least 1 other person. Here’s all the stuff you have to buy or rent:

Helical piles (shafts and extensions).
Pile caps / brackets.
Spray paint or stakes and string lines for pile layout.
Laser Level (to make sure pile heads are aligned) and grinder to cut pile tops flush.
Hand tools such as wrenches, sledgehammers, etc.
Hard hat, safety glasses, gloves, high-visibility vest, steel-toe boots.

The Cost of Helical Pile Machine Rental in Ontario

In Ontario, the cost of mini-excavator rentals range from $225 per day to $500. To add a hydraulic drive head to the machine, plan for a slightly higher budget.

Rental rates for mini excavators vary depending on the model and rental duration. Helical piles are quick to install, which means you likely won’t need the machine for more than one day. However, the table below shows rates for 1 day and 1 week, in case you need it for a longer period.

Machine	Rental Rate for 1 Day	Rental Rate for 1 Week
Bobcat E20 (3,428 lbs, 8 ft 6 in dig depth)	$250	$1,000
Bobcat E35/E40 (7,468 lbs, 10 ft 3 in dig depth)	$350	$1,400
Bobcat E55/E60 (12,271 lbs, 12 ft 11 in dig depth)	$400	$1,600
Kubota K008 (1 ton)	$350	$1,050

Hydraulic drive heads provide 5,000 to 12,000 ft-lbs torque for residential applications. When selecting a hydraulic drive head, consider the torque output and make sure to also match the flow rate (GPM) and pressure (PSI) of the excavator with the drive head requirements. Some rental companies offer torque monitoring gauges as add-ons, which is useful for documenting the depth and resistance.

What Other Costs Should You Plan For?

Contractors typically charge a flat price per pile up to a standard depth and add $20 to $25 per foot beyond that. If it’s a new construction, the cost per pile will make up the bulk of the bill. Repairs may require additional excavation and other costs depending on the degree of damage. However, always keep these factors in mind:

In short, more complex or hard-to-access projects take longer and increase labor expenses. Additional labor costs also include:

Why Hire Certified and Trained Professionals?

While renting the equipment is relatively straightforward, operating it safely and effectively is another story!

Although you are not legally required to have certification, it’s strongly recommended. If you’ve never operated hydraulic attachments before, hiring an experienced operator for a few hours could save time and prevent costly mistakes. If piles are misaligned, your shed or patio, for example, could collapse.

The Benefits of Helical Piles

Helical piles offer many benefits compared to concrete blocks or foundations. They are:

Efficient.
Quickly installated (usually on 1 day or less).
Environment-friendly.
Non-disruptive: they involve very little soil displacement and disturbance to landscaping.
Reusable: they can be removed and reused.

How to Reduce Your Rental Costs

In order to keep your rental costs down, you need to prepare carefully ahead of time. Make sure your pile layout is finalized before you go to the rental store.

You could also decide to rent the machine during off-peak seasons such as the Fall and early Spring. Rates can be a bit lower at this time.

If you only need to install a few piles, consider sharing the rental with a neighbor or friend doing a similar project. You could split both the equipment cost and transportation fees, cutting the bill in half.

Helical piles are very useful for building a host of residential structures such as patios, decks and house extensions. However, one challenge remains: installing screw piles requires specialized machinery. This type of equipment can be rented, but we recommend that it be operated by specialists.

With the right equipment and help from experts, your piles will be professionally installed and your construction very solid.

Helical Pile Foundation | Installation, Benefits, Cost

April 10, 2025 by Maude Gauthier

Poured concrete and concrete blocks are among the most common foundation types—but they can also cause significant problems in your basement over time. Many of these issues can be corrected, or even avoided entirely, by opting for a helical pile foundation.

More and more homeowners and builders are turning to helical piles, which offer a fast, clean, and more durable solution than traditional concrete foundations. Helical piles can be used for a wide range of projects: garden sheds, new cottages, concrete foundation repairs, gazebos, and more. In other words, the sky is the limit!

What Are the Benefits of a Helical Pile Foundation?

Not all helical piles are created equal. Let’s start with a quick definition. A helical pile is a manufactured steel foundation consisting of helix-shaped bearing plate(s) welded to a central shaft that is rotated into the ground. Helical piles come in various sizes and configurations, each designed to support different types of structures.

To get the most out of this type of foundation, it’s essential to choose high-quality piles and have them installed by experienced professionals.

You can expect the following benefits:

They are affordable.
Installation is quick (a few hours).
They are reusable (they can be removed and reinstalled elsewhere).
No excavation is required, which protects ecosystems and saves earth-moving costs.
They do not disturb the surrounding landscape.
They are ideal for tight or difficult-to-access areas.
They are appropriate for various soil types, including clay, sand, and rock.
They have a lifespan of up to 150 years.

Environmental Advantages of Screw Piles

If you're looking for a foundation system that leaves a smaller footprint, helical piles are an excellent solution. Unlike concrete foundations, which require extensive excavation and curing, screw piles minimize environmental disruption. There's no need for heavy earth-moving equipment or large amounts of concrete, reducing both emissions and waste. Therefore, helical piles are ideal for environmentally sensitive sites.

How Do Helical Piles Work?

Set at regular intervals, they are attached to the house by steel supports. The weight of the house is transferred and evenly distributed over the piles.

One of the most compelling advantages of screw piles is that they go deep into the ground, below the frost line, which is 7 to 8 feet deep. That’s what makes them so stable.

If these benefits sound appealing to you, please ask for quotes from local businesses.

What Can You Build on Screw Piles?

Screw piles are available in a variety of sizes and they can support different loads. Therefore, construction possibilities are endless, including:

Homes and cottages
Decks
Solar panels
Sunrooms
Docks
Garages
Sheds
Fences

What’s even more interesting is that helical piles may help you save money compared to a concrete foundation. Request quotes to compare prices.

What Are the Steps of a Successful Helical Piles Installation?

Screw piles can be used to reinforce existing foundations, or to replace a concrete foundation altogether.

Usually, in both cases, the job is entrusted to professionals. It is very important that you do not try to install them yourself because:

Professionals will come to your land or house and calculate how many piles are needed, depending on the weight of the building and soil type. Once they are installed professionally, helical piles offer long-term reliability. They don’t settle or shift the way concrete sometimes does. They are resistant to rust and corrosion when made from galvanized steel. They won’t crack, rot, or degrade over time. This means fewer repairs down the road and greater peace of mind for you!

Here is a summary of the main installation steps:

1.Know the load-bearing capacity you need

Installers need to know how much weight the helical piles have to support. To determine the load, you have to know what you are going to use the space for. A garage will need a bigger load-bearing capacity than a deck, for example.

2.Assessment

An engineer will visit your home to assess your soil in order to choose the right piles for a sturdy construction. Then you’ll be able to get the layout plan and ask for a permit, if the city where you live requires one. Engineers can not only select the right load-bearing capacity and determine the spacing between them, but also advise the installers throughout the project.

3.Installation

Screw piles installers mark the ground where the piles should go. Then they start digging, using hydraulic equipment to drive the piles. This equipment allows the screw piles to be installed below the frost line. Contractors generally use multi-powered torque heads and excavators. Smaller machines are also available if your backyard is difficult to access.

How Much Should You Budget for a Helical Pile Foundation ?

It’s impossible to determine a precise price for installing piles. So much goes into the price! There’s no one-size-fits-all answer.

A rough estimate of the spacing between two piles is 8 to 10 feet. This should give you an idea of the number of helical piles needed, and therefore the cost.

The soil type and the site, for instance, will impact the number of screw piles needed and the work to be done. Drilling will be harder in some soil types and will take up more time.

The price for a terrace, dock, garage or house is not the same, because of the weight to be supported.

All the following factors can also increase the costs:

The grade of the pile.
The quality (galvanized steel or not, for example).
The length of the shaft.
The type of soil.
Average labor rates in your area.
Customization, when necessary.
