August 14, 2025 by Laurence Perron-Légaré

Summary

Yes, as adaptable as they are, screw piles are highly suitable for a wide range of commercial structures. Engineered for efficiency and precision, they quickly provide a reliable foundation that meets strict Canadian commercial building requirements.

What are screw piles?

Invented in the early 1830s, they only gained real popularity over a hundred years later. Nowadays, to meet the highest industry standards, screw piles are the optimum modern foundation solution for commercial equipment and buildings across the country and the province.

Manufactured to be anchored deep into the ground, a pile has a simple design, a steel shaft with a helical blade. While it’s very basic, this setup gives it unparalleled robustness. Capable of supporting even the most demanding structures, a screw (or helical) pile is made up of 3 main components:

In Canadian ground, quality is non-negotiable. That’s why commercial-grade screw piles are certified by the Canadian Construction Materials Center (CCMC). This certification not only ensures strict conformity but also the highest quality standards.

How do they work? Using compact but powerful hydraulic machinery, each pile is rotated one by one into the ground. Once in place, the helical blade transfers the structure’s weight onto a more stable soil layer.

Are screw piles compatible with commercial structures?

Believe it or not, yes. From small structures to bigger ones, this system is fully capable of supporting commercial structures.

Why? Well, if you didn’t know already, the beauty of screw piles lies in their versatility. Each installation is engineered and entirely tailored. Whether that means handling heavy equipment loads, covering large floor areas, or adapting to tricky lots, screw piles are the answer.

Designed and installed based on detailed engineering calculations, they meet strict commercial building codes. While offering a foundation solution that’s surprisingly quick to put in place, the worksite disturbance is minimal, and the foundation will last for decades. Not just compatible, they are literally the smartest choice.

Why are screw piles suitable for commercial structures?

When it comes to meeting the demands of modern commercial projects, screw piles check all the boxes.

Designed to carry serious weight and adapt to whatever your building needs.

Hydraulic machinery anchors them in fast, much quicker than traditional foundations.

Even frozen ground isn’t a problem, keeping your project on schedule year-round.

Manufactured and certified to meet strict commercial building codes.

Each pile is chosen and installed based on the exact soil composition of the building site.

Easily combined with concrete slabs or grade beams for hybrid foundation solutions.

These advantages make them work as hard as a commercial project demands.

What type of common commercial applications are built on screw piles?

Trusted across all kinds of commercial projects, big or small, they deliver. That’s why you’ll often find them supporting:

Warehouses and distribution centers
Retail stores and shopping complexes
Office buildings and modular structures
Commercial signs and billboards
Boardwalks, piers, and outdoor commercial spaces

How to evaluate if screw piles suit your project?

The most reliable way to evaluate whether you could build a screw pile foundation is to contact a local company and get a professional opinion. To know for sure if this method is the right fit, they will assess your soil, load requirements, and project details.

When discussing your project, here are the key elements to look at:

A geotechnical assessment ensures the piles reach a stable load-bearing layer.
The total weight of the structure, which also includes people (yes), equipment and materials.
Project type and size, since different commercial builds require different pile specifications.
Compatibility with concrete grade beams, slabs, or hybrid foundation systems.
Compliance with building codes and engineering standards in your area.
Ensuring screw piles meet both your cost and scheduling timeline.

A proper assessment will show you that screw piles aren’t just possible, but the best fit.

Installation cost of screw piles for commercial structures

Sorry to break it to you, but you will not get a price in this paragraph. Not because we don’t want to, but because the cost of installing screw piles depends entirely on your site and the type of structure you plan on building.

Things like soil conditions, the building’s weight, pile size and depth, how easy the site is to access, and whether you’re combining them with other foundation materials all influence the final price.

However, what we can say for certain is that installing screw piles is quicker and more efficient than traditional foundations, which significantly cuts labor costs. And with their exceptional lifespan, they also deliver long-term savings by reducing the need for repairs or replacements.

With that being said, if you are interested in receiving an accurate estimate, ask for free quotes from specialized commercial screw pile installers. Are you ready to have your project assessed and the right solution engineer?

Disadvantages or limitations of screw piles for garages

In all honesty, no foundation system is perfect, and screw piles are no exception. While they work wonders in many situations, there are a few things to keep in mind.

They need to be installed by professionals with the right equipment, it’s absolutely not a weekend DIY project.
In areas with extremely soft or swampy soil, longer or reinforced piles are going to be needed, which will increase the price.
And while they’re built to last, they can’t magically fix poor site drainage, so water issues still need to be addressed.

Fortunately, with the support of an experienced team, these limitations are easy to plan for and rarely outweigh the benefits.

What types of garages can be supported by screw piles?

Screw piles support just about any garage design you have in mind. Whether it’s an attached garage that blends into your home or a detached garage set further back on your property, screw piles provide the stability you need.

They are equally at ease under a single-car garage, a double, or even a three-car setup with extra storage space. Because they are precisely positioned, screw piles adapt to different garage layouts without major excavation.

From small workshops to large vehicle shelters, they offer a strong, levelled base.

How many screw piles are needed to support a garage?

To build a garage foundation, the number of screw piles needed depends on the following:

A small single-car garage only needs a handful, while larger double or triple garages require more to handle the extra load. Installers usually space piles about 8 to 10 feet apart, placing them at corners, along the perimeter, and under critical load points.

Since there’s no universal number, a professional assessment is essential to calculate the exact amount and placement. This step is crucial as it ensures the stability of your garage.

Installation process of screw piles for garages

When done by experienced professionals, installing screw piles for a garage is an incredibly fast process. Here are the steps:

The installer checks soil conditions, garage plans, and access for machinery.

Exact spots are measured and marked to match the garage layout.

A hydraulic machine screws the steel piles deep into the ground.

Each pile is adjusted to ensure a perfectly level base.

These connect the piles to the garage’s frame or concrete slab.

The installer double-checks alignment, spacing, and stability.

Now that everything’s done, you are ready to build your garage. You don’t even have to wait hours, nor a day or two.

What preliminary verifications are required before installation?

Before installing screw piles for your garage, a few important checks ensure the job goes as planned. First, the soil needs to be assessed to determine its type, density, and depth of stable layers. This tells installers how deep the piles should go.

Next, the exact garage dimensions and load points are reviewed so piles can be placed for maximum support. Utility line locations, such as water, gas, and electricity, must be identified to avoid costly damage during drilling.

Finally, access for the installation equipment is verified. Luckily, there aren’t many cases where tight spaces allow the machinery to pass. Overall, taking the time for these verifications means your foundation will be safe and stable.

How much does it cost to install screw piles for a garage?

On average, the price per pile runs between 200$ and 300$, which includes both the pile itself and the installation. Does it sound high? Keep in mind, these aren’t your typical hardware-store piles. They’re patented, engineered, and approved by Canadian authorities, so you’re getting the best quality available on the market.

However, with that being said, you have to keep in mind that every garage is different. Size, layout, and soil conditions all affect the total number of piles required, so your final price will vary accordingly.

Helical & Screw Piles Foundation – Pros, Cons and Prices

August 13, 2025 by Laurence Perron-Légaré

Summary

Helical and screw pile foundations are fast to install, even during winter, mess-free, incredibly strong, stable, and eco-friendly. However, they do have limits, as they require proper installers and specialized machinery. While each pile costs between 200$ to 300$, the initial investment might surprise clients. But over time, this is one of the most economical foundation types, built to last for decades.

Are you planning on building a deck, a backyard shed, or even a house? If you don’t want to spend weeks excavating, pouring concrete, and waiting for it to cure, there is a fair chance that helical and screw piles might just be your answer.

These modern foundation systems offer strength, stability, and a significantly faster installation. However, before you hire anybody, let’s explore what they really are, the advantages, the disadvantages, and how much you can expect to pay.

What is a helical and screw piles foundation?

Picture giant metal screws with a helical blade at their tip. Drilled deep into the ground, they together hold up entire structures.

Made of anti-corrosion steel, these piles are turned into the soil using specialized hydraulic machinery. Firmly anchored into almost any kind of soil, they eliminate the need for massive concrete footings. Once in place, they support decks, cottages, home extensions, and full houses.

The beauty of it is that they’re quick to install, even during the colder winter months, cause minimal disturbance to your yard, and you are able to build right away. You don’t have to wait for anything to dry. This modern process is an efficient alternative to traditional foundations.

Advantages of helical & screw piles foundation

Helical and screw piles aren’t just another building trend. Introduced in the 1900s, they genuinely make life easier for both homeowners and contractors.

If you want to learn more, here’s why so many people are now choosing them over traditional foundations:

No waiting for concrete to cure, and if you didn’t know, you can build the same day they’re installed.

Forget giant holes and mountains of dirt. The ground stays neat, and your landscaping barely notices.

Yes, they can be installed even in frozen ground, which is perfect for Canada’s unpredictable weather.

Designed to handle light and heavy loads, they offer long-lasting support for many projects.

If you ever need to move or reuse them for another project, it’s surprisingly doable and straightforward.

Compared to other types of foundations, there is way less soil disruption. That means a smaller environmental footprint.

Quick installation and minimal excavation

One of the biggest advantages of helical and screw piles is how fast they turn into a full, strong foundation. With that statement, we are talking hours, not days. Can you imagine? You can have a complete foundation built in half a day.

How does that work?

The whole process is so clean that your lawn or landscaping barely looks disturbed. Even better, you can start building right after the last pile is installed. That means no downtime for your project and more time actually enjoying it. That’s life-changing, right?

Strong load-bearing capacity

Do not let their simple appearance fool you. Pile foundations are very surprising when it comes to strength. Anchored solidly into the ground, this system provides any structure with a rock-solid base that won’t budge.

Very adaptable, these piles can handle light but also heavy loads without breaking a sweat. Because they are screwed right into stable soil layers, below the frost line to be precise, they distribute the weight evenly and keep everything steady, even on tricky or uneven ground.

Suitable for various soil conditions

One of the coolest things about helical and screw piles is how suitable they are. What is your ground made of?

The soil composition isn’t a problem. In fact, without relying on the perfect soil, these piles actually work with the natural ground underneath. They find their grip and hold tight.

With the know-how of a professional team, a customized solution is provided to suit your specific soil conditions and project needs. In that way, maximum stability is ensured, always.

This characteristic makes them a lifesaver in places where traditional foundations struggle or require expensive preparation work. Drilled deep down, they bypass weak or unstable layers and are anchored into very solid soil.

Disadvantages of helical & screw piles foundation

While helical and screw piles have a lot going for them, they’re not perfect for every situation. Here are a few things to keep in mind:

While they are cheaper in the long term, they sometimes are pricier initially compared to some traditional foundations, especially for smaller projects.

If your soil is packed with huge boulders, installing piles can get tricky or even impossible. To evaluate the feasibility, a professional opinion is needed.

You can’t just do it yourself with a drill. The installation requires hydraulic machinery and experienced operators.

While strong, they have limits. Extremely heavy industrial projects might need something more heavy-duty.

Higher initial cost in some cases

It’s no secret. Helical and screw piles might occasionally cost more upfront compared to traditional concrete footings, but not always.

This is mainly because the materials are steel, and the installation needs specialized equipment and skilled hands. For smaller jobs or simpler soil conditions, the cost difference might make you pause. But here’s the thing. That initial investment pays off with:

When you look at the whole picture, it actually is a smarter choice for many projects.

Not always ideal for very rocky ground

If your land is composed of bedrock just beneath the surface, it might complicate the installation.

While the professionals, have over time, developed proper drilling techniques compatible with rocky ground, the crew might need to add steps to the process. Blasting or pre-drilling to clear a path adds some extra time, and the cost is likely to increase.

However, for some foundations, hitting a large rock can stop the process cold or even damage the pile itself. So before committing to screw piles, if your land feels more like an obstacle, it’s worth getting an expert’s opinion.

Requires specialized installation equipment

To be properly installed, these bad boys need a special hydraulic machine. That means you’ll need a team that knows what they’re doing and uses the right gear.

This specialized setup isn’t something every contractor has on hand, which limits the options. However, when you hire the right knowledgeable company, and there are plenty, you don’t have to worry about that.

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.

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?

You want to build a deck? A new shed is your next project? Your family would benefit from a garden room or small home extension? Screw piles can be used for a wide range of applications including:

Foundations for Modular Homes: Why Choose Helical Piles?

July 2, 2025 by Laurence Perron-Légaré

For a while now, modular homes have been gaining serious popularity, and it’s not hard to see why. Built indoors in a controlled environment, they avoid weather constraints, reduce waste, and deliver consistent, superior quality construction. Once completed, the home is transported directly to the final location, ready for installation.

However, upon their arrival, there is only one element that can bring the project to an end: The foundation! That’s the step that locks your home to the land and gets the ball rolling.

Especially for modular homes, when it comes to choosing the right type of foundation, helical piles make way more sense.

What are helical piles?

Helical piles are long steel piles with helical (spiral-shaped) blades at the bottom, kind of like giant screws for your foundation. They’re drilled deep into the ground using specialized machinery until they reach stable soil.

Once in place, they provide a solid, stable base that supports all types of structures, including modular homes.

One of the biggest advantages of this type of foundation is speed. Compared to traditional concrete foundations, which take days or even weeks to pour and cure, helical piles are installed up to ten times faster. In many cases, the installation is done in just one day, and your home is placed right after.

Quick, clean, and incredibly strong, helical piles are changing the way we think about foundations.

Do you want to learn more about helical piles? Feel free to reach out to us! Within hours, our team will connect you with an experienced installer who’s happily waiting to answer all your questions.

What are the different types of modular home foundations commonly built?

When it comes to setting your modular home on a solid base, there are a few common foundation options to consider.

Here are the most popular types:

Helical piles: Screwed into the ground, they offer fast installation, minimal site disruption, and excellent stability, which is perfect for uneven or challenging terrain.
Concrete slab: A large, flat, poured concrete surface that acts as both foundation and floor. It’s durable and low maintenance, but requires more time to build.
Concrete blocks: These stacked blocks create a crawl space or basement foundation. They offer good insulation and access to utilities but involve more labor.

To make sure your modular home stays exactly where it’s supposed to be, choosing the right foundation is key.

Why choose helical piles for modular homes over other foundation systems?

The main reason helical piles are often selected for modular homes lies in how well they fit the unique nature of this construction method. Since modular homes are built off-site and then transported, their foundations need to be precise, reliable, and ready to support installation without delay.

Helical piles are designed to be installed quickly and with great accuracy.
It’s allowing builders to coordinate the foundation work closely with the arrival of the modules.
They also work well in locations where traditional foundations might be difficult, such as uneven terrain or soil with poor bearing capacity.

Because they don’t require extensive excavation or curing time, helical piles align perfectly with the modular home’s streamlined factory-built process.

Most of the time, helical piles emerge as the obvious and practical foundation.

What are the advantages of using helical piles for modular or manufactured homes?

Helical piles bring a range of perks that perfectly match the characteristics and needs of modular homes. Why? Because their design and installation process offer practical solutions to common foundation challenges.

As an increasingly popular choice, here are some of the main advantages:

Rapid installation (a few hours)
Damaged-free installation
Stable structure for years
Perfectly level base
No waiting required
Maintenance-free
Certified and guaranteed technology

With all these benefits combined, it’s no surprise that more and more builders and homeowners are turning to helical piles for modular home foundations. Their ability to simplify the installation process is just unbeatable.

How many screw piles need to be installed for a modular home foundation?

Since every project is different, the number of screw piles required for a modular home varies quite a bit. However, it is safe to say that on average, most modular home foundations need somewhere between 18 and 36 helical piles.

When calculating the number of piles required, several factors come into play.

For example, a smaller, lighter home on solid ground needs fewer piles, while a larger structure or softer soil requires more to ensure proper support.

That is why a site assessment by a qualified installer is so important. They evaluate the ground and the structure’s needs to determine the exact number of piles required. That step ensures your home rests on a stable and secure foundation from day one.

How deep do helical piles go in the ground to support a modular home?

Helical piles are designed to go deep enough into the ground to reach stable, load-bearing soil. In Canada, for most modular homes, that means a depth of around 7 to 10 feet.

However, the exact depth fluctuates depending on the type of soil on your property. In areas with soft or loose ground, the piles need to be driven deeper to ensure a solid anchor.

All in all, the goal is to always reach a point where the pile is safely and securely supporting the weight of your home without shifting or settling over time. Installers use specialized equipment to measure resistance during installation, making sure each pile is placed at the right depth for maximum stability.

What is the life expectancy of piles for modular homes?

When properly installed and made with high-quality, galvanized steel, these piles have impressive durability. They last anywhere between 75 to 150 years.

That means once your modular home is in place, you won’t have to worry about the foundation shifting or weakening any time soon, possibly not even in your lifetime!

This long lifespan comes from the corrosion-resistant coating that protects the steel over time.
Installed deep enough to stay stable, they are far from surface moisture and weather changes.
As long as the installation is done by a qualified professional and the right pile type is selected for your soil conditions.

As a long-term investment, piles are built to last and keep your modular home firmly in place for generations.

What kind of warranty is offered with the installation of helical piles for modular homes?

Knowing your foundation is protected offers real peace of mind, especially when you’re investing in a modular home. Most certified helical pile installers provide long-term warranties that reflect the reliability and durability of the system.

In Canada, you often see warranties of up to 75 years, and in some cases, even a lifetime warranty,. It depends on the company and the installer you hire.

These warranties generally cover:

It’s important to note that to benefit from these protections, the installation must be done by a certified professional using approved, high-quality materials. If it’s not done by a certified installer, you won’t be covered, and that’s a risk you don’t want to take.

What kind of equipment is used to screw the piles?

Installing helical piles might sound like a big job, but the equipment used is surprisingly compact and efficient.

To screw the piles into the ground, professionals typically use a small machine equipped with a specialized hydraulic drive head. This tool gives the installer full control over the speed, depth, and torque, ensuring each pile is anchored properly in stable soil.

Lightweight and mobile, it means that this equipment is able to access tight spaces and is even used on properties with limited access or uneven terrain. For this type of foundation, there’s absolutely no need for large, disruptive machinery or heavy concrete mixers.

Precise, fast and surprisingly clean, the installation process keeps your land intact while giving your modular home a strong and lasting foundation. It’s a high-tech approach to what used to be a messy and time-consuming part of construction.

How much does it cost to install helical piles for modular homes?

The total cost of installing helical piles for a modular home is based on a series of factors. On average, expect to pay between 200$ and 600$ per pile, including installation.

For a regular modular home that requires anywhere from 18 to 36 piles, that brings the total foundation cost to roughly 3 600$ to 21 600$.

While it might seem like a big investment upfront, it’s important to remember that helical piles don’t require a lot of time to install, no maintenance at all and are made to last for a lifetime.

Needless to say that over time, helical piles are much more economical than traditional concrete foundations.

Before building a deck, a shed, a house extension, a full house or a commercial building, you need to make one key decision. What type of foundation to use? Across Canada, most homeowners end up weighing two options: screw piles or concrete foundations.

Each has its advantages and disadvantages, and the right choice depends on the type of project, soil composition, budget and timeline.

To help you figure out which one is best for your project, you must start by understanding what are screw piles versus concrete foundations.

What are screw piles?

Screw piles, also known as helical piles, are a type of deep foundation system that’s installed by literally screwing them into the ground. Think of them as giant metal screws with helical blades at the bottom, designed to anchor your structure firmly into the soil.

Made of galvanized steel, they are installed quickly with specialized hydraulic machinery. Because they twist deep into stable soil layers, they provide excellent load-bearing support and are especially great for uneven or unstable ground.

What makes screw piles stand out?

Often ready to use in just a few hours or at most a few days for a bigger project.
Summer, fall, winter, spring, the installation can be performed year-round.
Since no digging is required, they cause minimal disruption to your yard.
Removable and reusable, it’s an eco-friendly option in many cases.

The screw piles are a modern alternative to traditional concrete foundations.

What are concrete foundations?

Concrete foundations are the classic choice, the kind of base most people picture when they think of construction. It’s a big pour of concrete, shaped with wooden forms, that hardens into a solid, permanent base for your project. Concrete has been trusted for generations to hold things up.

There are different types depending on what you’re building, but the main idea is the same. It involves digging, pouring, waiting for it to cure, and ending up with a base that’s built to last.

What is the upside?

What is the downside?

If you are looking for long-term strength and you’re not in a rush, concrete might be a good bet.

Screw piles vs concrete foundations - Advantages and Disadvantages

Now that you are more familiar with what screw piles and concrete foundations are, let’s dive into the pros and cons.

To help you weigh your options, here’s a simple breakdown of each type of foundation:

Types of application - Screw piles vs concrete foundations

Still unsure which option fits your project? Sometimes, the best way to decide is to look at how each type of foundation is commonly used. Screw piles and concrete foundations don’t compete so much as they each shine in different situations.

Screw piles are perfect when you want speed, flexibility, and minimal disruption, like for outdoor projects or seasonal work. Concrete, on the other hand, is better for big, heavy, long-term builds that require serious support.

Here’s a quick overview:

Decks, patios
Docks, boathouses
Backyard sheds
Fences, pergolas
Tiny homes, small cabins
Temporary or seasonal structures
House extensions, sunrooms
Homes, cottages
Commercial or industrial buildings

Of course, that’s not all. Both types of foundations can be adapted to many other projects.

What are the key differences between screw piles vs concrete foundations?

At first, screw piles and concrete foundations might seem like two ways to achieve the same result. But when you dig a little deeper, the differences become pretty clear.

So if you’re torn between the two options and are interested in learning more about what sets them apart, this side-by-side breakdown will help you see the big picture.

Key differences comparison

Key differences	Screw piles	Concrete foundations
Strength	Strong enough for most residential/light commercial projects	Extremely strong, best for heavy and large-scale structures
Installation speed	Very fast, often complete in a few hours	Slower, requires several days (including curing time)
Site disruption	Minimal, no large excavation or mess	High, requires digging, forming, and potential yard damage
Weather conditions	Can be installed in any kind of weather	Weather-dependent, delays may occur in cold or wet seasons
Lifespan (durability)	75+ years with proper installation and corrosion protection	80-100+ years if well-built and maintained
Maintenance	Virtually none if installed correctly	Minimal, but may develop cracks or shif over time
Upfront price	Often slightly more expensive	Usually lower in materials, but more labor-intensive
Long-term savings	Save time and costs over the years	Costs may increase with maintenance

From installation time and weather flexibility to long-term costs and maintenance, each option has its own strengths and compromises.

Why do people sometimes combine screw piles and concrete?

Is a mix of both systems the optimal foundation strategy? It might surprise you, but it could be. Many builders and homeowners don’t just pick one or the other, they combine screw piles and concrete to get the best of both worlds.

Why? Because each system brings something unique to the table, and together, they can create a foundation that’s even more reliable.

A more solid and secure foundation overall
More freedom to adapt to different building layouts
Less shifting or settling over time
Fast pile installation with minimal delays
Fewer issues to fix in the long run
Built to last for decades

For many projects, mixing the two can be a smart and strategic choice.

How to decide between screw piles and concrete foundations?

So what is the final verdict, screw piles or concrete? The truth is, there’s no universal answer. It really comes down to your project, your priorities, and the conditions on your site.

That said, the list of advantages that screw piles bring to the table is hard to ignore and undeniable: fast installation, minimal mess, year-round flexibility, and impressive durability. That’s why, for many projects, screw piles have become the preferred choice. They make building faster, simpler, and more cost-effective in the long run.

Of course, concrete still has its place. But if you’re looking for efficiency and versatility, screw piles are definitely worth considering, and for many, they’re the smarter modern foundation.
