STRAIGHT ANSWERS ON SCREW PILES

Cost depends on the number of piles, pile diameter, site conditions, and your region. A standard residential deck (6 to 10 piles) typically runs from $1,500 to $4,500 installed. The only accurate number comes from a site-specific quote. Get a free quote.

Yes, for most residential and light commercial applications. Every Postech screw pile is torque-verified during installation, so load capacity is confirmed in the field on each pile. Concrete footings offer no equivalent in-field check. See the full comparison.

Most residential projects are completed in one day by a two-person certified crew, and you can typically build the same day. Concrete requires excavation, forming, pouring, and a cure period of at least 24 to 48 hours before loading.

Postech piles are hot-dip galvanized as part of the engineering specification, not as an afterthought. The zinc coating bonds metallurgically to the steel to resist corrosion over the life of the structure. The coating is matched to your site's soil. See product specs.

Yes. Unlike concrete, screw pile installation is not weather-dependent. Certified Postech installers work year-round, including in frozen ground, because piles are driven well below the frost line. Surface frost does not stop installation.

Piles are anchored below the frost line, in stable soil that does not freeze and expand seasonally. A calculated clearance is kept between the soil surface and your structure, so surface soil can heave without contacting it. How screw piles work.

Yes, and it is a practical advantage over concrete. Pile depth and bracket height are field-adjustable, so an installer can compensate for grade changes and deliver a level structure regardless of slope. Your installer assesses the site and specifies the approach.

No. Postech piles are installed only by certified dealers trained on equipment calibration, torque verification, load calculation, and code compliance. Self-installation is not covered under warranty and would not meet building code requirements for permitted structures. Find a certified installer.

Yes. Postech installations carry a limited lifetime warranty against frost heave when installed by a certified Postech dealer. Ask your installer for the complete warranty document before work begins.
