A concrete foundation takes two to five days of work, plus 24 to 48 hours of curing before you can build on it. A screw pile is ready the moment it is installed, in one day. That is several days back on your schedule.
SCREW PILES OR CONCRETE
TWO FOUNDATIONS. TWO WAYS TO BUILD.
Concrete, you pour and wait. A screw pile, you turn into the ground and build on the same day. Here is the honest comparison, so your project can decide.
Install today. Build tomorrow.
Frost rises. The pile holds.
In a freeze-thaw climate, frost lifts anything that is not anchored deep enough. A footing set too shallow can crack or shift. A screw pile turns down below the frost line, so it does not move, and that is backed by a written limited lifetime warranty against frost heave (see full terms).
Side by side, on the facts.

When concrete is still the right call.
For a large structure that needs a full slab or a poured wall, concrete is often what the code requires, and it is the right choice. For most residential projects (decks, additions, sunrooms, sheds), screw piles do the job, and faster.
COMMON QUESTIONS
Screw Piles vs Concrete, Answered
Yes, for residential and light commercial applications.
Load-bearing capacity is engineer-calculated and verified at installation.
Postech screw piles meet building code requirements across Canadian provinces and US states for decks, sunrooms, additions, sheds, and residential foundations.
Properly installed screw piles do not move with frost.
Your local Postech certified installer first makes sure to drive every pile past the frost line before stopping, anchoring it in stable, unfrozen soil.
Postech's Thermal Pileâ„¢ technology then insulates the inside of the steel tube, preventing ice formation at the pile base all year long, where uninsulated piles typically fail.
For heavy structures requiring a full slab or load-bearing concrete wall, poured concrete may be required by local building codes.
Otherwise, for most residential projects, screw piles meet all applicable code requirements.
Screw pile cost depends on 3 main variables: the number of piles required, soil conditions on your site, and local labour rates.
Total project cost is typically comparable to or lower than concrete when excavation and site restoration are factored in.

Yes. Postech piles are backed by 4 independent certifications:
- CCMC (Canadian Construction Materials Centre): accepted by building inspectors and engineers across Canada without additional justification.
- ICC-ES: US equivalent, meets International Building Code (IBC) and International Residential Code (IRC).
- ISO 9001: quality management certification covering manufacturing at our Sherbrooke, QC (Canada) facility.
- CWB: Canadian Welding Bureau certification on all steel fabrication.
Every installer also completes Postech's own certification program before their first job. The limited lifetime warranty applies only when installed by a certified Postech dealer.
The best judge is your project.
Ask for two quotes and compare the real cost, start to finish. A certified installer reads your soil and gives you a clear price. Starting off on a solid foundation since 1995.
