True Pitch Screw Piles for Fast, Reliable Foundations
Why Choose True Pitch Screw Piles
True Helix Design
Pressed to form a true pitch flighting, our helixes maintain a constant slope and a right angle to the pipe, improving installation accuracy and long-term reliability. Available in 4”–14” pitch formations, they ensure even load distribution across the helix surface while minimizing ground disturbance during installation.
Fast Installation
Installed in hours instead of days, screw piles require no curing time. Structures can be built immediately, keeping projects on schedule and reducing overall construction time.
Precision Fit
Our helix features a beveled leading edge that cuts cleanly through frozen and dense soils with reduced slippage during installation. A high-definition cut ensures precise fit-up to the pipe, producing strong, consistent weld quality.
What Are True Pitch Screw Piles
Engineered Steel Foundations
Designed for Specific Soil Conditions
Torque-Controlled Installation
Immediate Load-Bearing Capacity
True Pitch Screw Piles are advanced foundation systems that use engineered steel shafts with helical plates to anchor structures securely into the soil. A central steel shaft with welded helix plates spaced 3x of the plate diameter.

Projects & Use Cases
Benefits to helical pile products is that they can connect to many different structures including Caps, Brackets, Tiebacks & more!
Transmission Tower Foundations
Engineered screw piles were used to support transmission towers in areas with variable soil conditions, allowing for fast installation and immediate loading while minimizing environmental disturbance.
Utility & Power Grid Infrastructure
Solar Farm Structures
Screw pile systems provided a cost-effective and sustainable foundation for solar panel arrays, enabling rapid deployment and precise alignment without the need for concrete foundations.
Frequently Asked Questions
What are True Pitch Screw Piles used for?
At Inland Screwpiling in Coaldale, our helix-designed screw piles are used to support structural loads for decks, garages, additions, RTM homes, commercial buildings, and agricultural structures across Southern Alberta. The helical plates anchor into undisturbed soil below frost depth, providing strong bearing capacity and resistance to uplift from wind or expansive clay soils. During installation, we monitor torque to verify load capacity in real time, ensuring the pile meets engineered specifications — giving you a foundation that’s built for Alberta conditions and built to last.
Who installs our screw piles?
We do have an installation team that handles Alberta projects. For more expansive projects outside of Alberta, let us know and we can help find the right company for installation.
Can screw piles be installed in difficult soil conditions?
The helical plates advance into undisturbed soil below unstable layers, allowing us to bypass weak material and lock into competent bearing soil. Because we monitor installation torque, we can verify load capacity as we install — so we’re not guessing what’s happening underground.
Are screw piles more expensive than concrete foundations?
Compared to a concrete foundation, helical screw piles often cost less or very similar on straightforward installs — especially in Southern Alberta soils where digging, forming, and backfill can be a real money-eater. You avoid excavation costs, no footings to dig out in clay or coulee fill, and there’s no curing time holding up your build.
How long does installation typically take?
Installation typically takes a few hours, depending on the number of piles and site conditions. Structures can be loaded immediately after installation.
Are screw piles environmentally friendly?
Yes, screw piles are an environmentally responsible foundation option. They require minimal excavation, create very little site disturbance, and eliminate the need for concrete trucks, curing water, and excess soil removal. Because they advance into undisturbed soil, they preserve the surrounding ground structure, which is ideal for farmland, coulees, and landscaped properties. Steel screw piles are also removable and recyclable, reducing long-term environmental impact compared to traditional concrete foundations.
