Helical piles are steel posts with round plates at the bottom. Many people also call them screw piles. These piles turn into the ground like a large screw. This simple method creates strong support for many structures.
In Toronto and the Greater Toronto Area, soil can shift, freeze, or hold water. Because of this, many builders now prefer helical piles for decks, additions, and small foundations. They want support that stays stable in local soil all year.
How Helical Piles Work
A helical pile works by gripping the soil as it rotates into the ground. The plates create strong resistance. This helps the pile carry weight without sinking or moving.
A hydraulic machine installs the pile. The machine turns the pile until it reaches strong soil. The torque reading shows the load the pile can carry.
When the pile reaches the right depth, the installer adds a bracket or top plate. The structure sits on this plate.
How Deep Do Helical Piles Go
The depth depends on soil type. Toronto and GTA areas have clay, wet soil, and mixed layers. These conditions often need deeper piles.
Many piles in this region reach between eight and twenty feet. The installer checks torque to confirm safe support.
Where You Can Use Helical Piles
Helical piles work for many projects. They are strong, flexible, and safe for different soil types.
Common uses include:
- Decks
- Porches
- Home additions
- Sunrooms
- Fences
- Retaining walls
- Small building foundations
Builders choose them because they offer stable support and work well in clay or cold weather.
Are Helical Piles Good for Decks
Yes. They are one of the best choices for deck foundations. Decks in Toronto often face frost heave. Frost heave happens when the soil freezes and pushes concrete footings up.
Helical piles stay below the frost line. They lock into deep and firm soil. This keeps the deck level and safe.
Helical Piles and Toronto Soil Conditions
Toronto and the GTA have many clay zones. Clay holds water and expands when the weather changes. Concrete footings often fail in clay.
Helical piles handle clay soil better. The plates grip the soil. The steel shaft stays firm. The foundation stays stable even when the ground shifts.
Cold weather is also a challenge. Concrete needs warm weather to cure. Helical piles do not. Installers can place them in winter with no delay.
Helical Piles vs Concrete Footings
Many homeowners compare helical piles and concrete footings. Here is the simple difference.
Concrete footings need digging. They need forms. They need time to cure. They may crack. They may shift with frost.
Helical piles install fast. They work in all seasons. They resist frost movement. They handle heavy loads. They need no large holes.
This is why many contractors in Toronto now choose helical piles for decks and additions.
How Much Do Helical Piles Cost in Toronto
The cost of helical piles in Toronto depends on soil, depth, and load needs. Every property in the GTA is different. A proper site check is the only way to know the final cost.

How Long Do Helical Piles Last
Helical piles can last many decades. They use strong steel. Many systems also use a protective coating to prevent rust. When installed the right way, they act as a permanent foundation.
Can Helical Piles Fail
Failure is rare when a trained team installs them. Problems happen only when the pile is too short, the torque is not checked, or the soil is not tested.
A professional installer knows how to avoid these issues.
Helical Pile Installation in Toronto and the GTA
A trusted installer starts with a site check. They review soil type, layout, and load needs.
Next, they install the piles with a hydraulic machine. They watch torque and depth in real time. This ensures safe support.
Installation is fast. Many projects finish in one day. There is no mess. There is no waiting time like concrete.
This is why many Toronto homeowners now choose helical piles for their deck and porch foundations.
