Frequently Asked Questions

Screw piles are steel foundation systems with one or more helical plates welded to a central shaft. They are mechanically advanced into the ground to support structural loads by transferring weight into stable, undisturbed soil below frost depth.

Screw piles are used for decks, garages, additions, RTM homes, commercial buildings, agricultural structures, power stations, solar arrays, and transmission lines. They are ideal for projects requiring engineered load capacity and reliable performance in Alberta’s soil conditions.

Most screw piles take 10–30 minutes per pile to install, depending on soil conditions and required depth. A typical residential project can often be completed in a single day.

Yes, screw piles are fully load-bearing immediately after installation. There is no curing time required, allowing construction to begin right away.

True Pitch Screw Piles are engineered with specific plate sizes and spacing to meet structural load requirements. They are installed using torque monitoring to verify capacity in real time, unlike light-duty or non-engineered piles.

Properly engineered and installed screw piles are designed to last 50+ years. Longevity depends on soil conditions, coating specifications, and project requirements.

Yes, engineered screw piles are designed and installed to meet applicable building codes and engineering standards. Installation torque is recorded to confirm load capacity meets project specifications.

Yes, screw piles perform well in clay, soft soils, backfill, and areas with high moisture. They can bypass weak surface material and anchor into stronger soil layers below.

Load capacity is verified by measuring installation torque during the piling process. Torque correlates directly to bearing capacity, providing real-time confirmation that engineered requirements are achieved.

Installation is fast and minimally disruptive compared to traditional excavation. There is no large-scale digging, concrete pouring, or extensive site disturbance.

Yes, compact hydraulic equipment allows installation in backyards, near existing structures, and other limited-access locations where larger machinery cannot operate.

n many cases, screw piles are comparable or more cost-effective than concrete when factoring in labour, excavation, equipment, and curing time. They can reduce project delays and overall construction costs.

Screw piles require minimal excavation and create little site disturbance. They eliminate the need for concrete trucks and excess spoil removal, reducing environmental impact.
