What Are Helical Piles?
Helical piles — sometimes called helical piers, screw piles, or ground anchors — are galvanized steel foundation posts fitted with helix plates that are screwed directly into the ground. Unlike poured concrete, which needs time to cure before it can bear weight, a helical pile is load-bearing the moment it's installed, letting your project move forward the same day.
Fast
No curing time. Piles are load-bearing immediately after installation.
All-Season
Installs in a wider range of ground and weather conditions than poured concrete footings.
Minimal Disturbance
No excavation, forms, or curing mess — a cleaner install for your property.
Reliable in Soft Soil
Unaffected by high water tables or unstable soil that can undermine traditional footings.
How Helical Piles Work
A high-torque drive motor — typically mounted on an excavator or skid steer — screws the pile shaft into the ground until it reaches load-bearing soil. The weight of the structure above transfers down the shaft to the helix plates, which anchor firmly below grade. Because the pile is driven to a measured torque rather than a fixed depth, installers can confirm the foundation has reached adequate bearing capacity before moving on to the next post.
Common Applications
Decks & Porches
A fast, level foundation for new deck builds and rebuilds.
Sheds & Outbuildings
A clean, mess-free foundation for prefab or custom-built structures.
Fences & Gates
Stable, frost-resistant posts for fence lines and gate assemblies.
Additions & Cottages
Reliable footings for structures on soft or uneven ground.
Docks
Galvanized steel piles anchored to a specified torque for dependable waterfront support.
Foundation Repair
Stabilize and level an existing foundation without full excavation.
Frequently Asked Questions
What are helical piles?
Helical piles, sometimes called helical piers or screw piles, are steel foundation and anchoring posts with helix plates that are screwed into the ground. Unlike concrete, they are load-bearing immediately after installation, with no curing time required.
How do helical piles work?
A helical pile is driven into the ground using a high-torque drive motor attached to equipment such as an excavator or skid steer. The load from the structure above transfers down the shaft to the helix plates, which anchor into stable soil below grade. Helical piles remain effective even in high water tables or caving soil conditions.
Are helical piles faster than concrete footings?
Yes. Helical piles are load-bearing the moment installation is complete, unlike concrete, which needs time to cure. This allows construction to continue the same day, extending the usable work season into colder months.
What projects are helical piles used for?
Helical piles are commonly used for decks, sheds, fences, additions, cottages, docks, solar panel arrays, and foundation repair or underpinning work.
