What is a helical pile?

A helical pile, also called a screw pile, is a steel shaft with one or more helical plates welded near the tip. A hydraulic drive turns the pile into the ground like a large screw until it reaches soil dense enough to carry the load. Because the pile anchors below the frost line, it resists heave and settlement, and it can carry weight right after installation with no concrete cure time.

Winter Application & Advantages

Helical piles are the ultimate solution for Ontario’s frozen terrain, effectively eliminating the traditional construction “off-season.” Unlike concrete, which requires expensive heating, chemical additives, and specialized hoarding to cure in the cold, helical piles are mechanically driven deep below the frost line into stable, non-frozen soil. This process allows for precise installation in temperatures as low as -30°C without the risk of frost heave or seasonal shifting, ensuring your project stays on schedule even in the dead of January.



Summer Application & Advantages

During the warmer months, the primary advantage of helical piles is the total preservation of your property’s landscaping and the speed of the build. While traditional summer projects are often delayed by massive excavation, piles of dirt, and the long curing cycles of concrete footings, our lightweight hydraulic equipment installs screw piles with zero mess. You avoid the “28-day wait” entirely, allowing you to begin framing your deck, addition, or pool house the very same hour the installation is complete, maximizing your time in the sun.

Total Ground Movement Protection

Protection Inside and Out.

Our helical piles are engineered to provide a permanent foundation solution that thrives in Ontario’s toughest environments. By focusing on deep-earth anchoring and superior material protection, we eliminate the risks associated with traditional concrete footings.

01.

Our screw piles are driven deep below the frost line, anchoring into stable, non-frozen soil. This mechanical installation effectively eliminates “frost heave” and shifting caused by extreme freeze-thaw cycles, ensuring your structure remains level and secure year-round.

02.

Our piles are cold-formed from ASTM A500 Grade C structural steel tube and finished with a full hot-dip galvanized coating. That coating protects the shafts, heads and helices from rust, which is what gives a steel foundation its long service life in wet Ontario ground. The exact steel figures are in the spec table below, stated once so they cannot drift.

Galvanized Steel + ZN Protection

Our advanced galvanizing process protects the steel against corrosion, ensuring maximum durability and long-term performance. Designed for even the most demanding projects, our screw piles deliver lasting strength, no matter the environment.

Technical Specifications

Every pile we install is cold-formed from ASTM A500 Grade C structural steel tube, hot-dip galvanized, and torque-verified in the ground to the load your engineer specified. Capacity is correlated from installation torque using the method in ICC-ES AC358, the acceptance criteria for helical pile systems. The numbers are in the spec table below, and the mill certificate and product evaluation report for your project are available on request.

Helical piles vs concrete footings

Most people comparing the two care about four things: how long the site is tied up, whether the foundation will move over winter, what happens on soft or wet ground, and the real all-in cost once excavation and disposal are counted. Helical piles carry load the day they go in, bear below the frost line, and keep going until the torque says the soil is competent. Poured concrete still makes sense when the design needs a full basement or a continuous slab.

We put the full side-by-side in one place: helical piles vs concrete footings. If you are new to the system, start with what are helical piles.

Helical pile FAQs

A helical pile foundation supports a structure on steel piles screwed into the ground instead of poured concrete footings. Each pile is turned down until it reaches soil that can carry the design load, then the structure connects to a bracket on top. It works well on soft, wet, or frost-prone ground.

Depth depends on the soil. Piles are driven until the installation torque shows they have reached firm, load-bearing ground. In much of Ontario that is anywhere from about 10 feet to more than 30 feet, and always below the local frost line.

Capacity depends on the pile size and the soil. Larger shafts and helix plates carry more, and the crew confirms the capacity from the torque reading as each pile goes in. Your engineer sets the required capacity for the project.

For many projects, yes. They install in hours with no excavation or cure time, they reach below the frost line, and they hold in soil where poured footings would shift. A full concrete basement can still make sense on some builds.

Yes. They are screwed into the ground below the frost line rather than poured, so freezing temperatures do not affect the install the way they affect concrete. That makes them a common choice for winter builds across Ontario.
