FOUNDATION STABILIZATION WITH SCREW PILES

Yes. Postech screw piles are regularly installed under existing decks, cottages, and sheds without removing the structure above.

Our compact equipment accesses the site through standard gate openings as narrow as 36 inches. Most repairs are completed in a single day.

Installation depth depends on soil conditions and load requirements, but piles are typically driven 5 to 8 feet deep, always below the frost line, until they reach stable, load-bearing ground.

Your certified Postech installer will assess site conditions before work begins and confirm the required depth.

Postech screw piles always extend below the frost line, the layer of soil that freezes and moves each winter.

This means that once they are installed at the correct depth, they are unaffected by seasonal freeze-thaw cycles. The movement that caused the original damage cannot repeat.

Permit requirements vary by municipality.

In most residential cases, foundation repair with screw piles does not require a permit, but your local Postech installer can confirm what applies in your area before any work begins.

Cost depends on the number of piles required, soil conditions, and the size of the structure. Postech stabilization is typically significantly less expensive than full concrete replacement, with no excavation costs and no curing delays.

Yes. All Postech installations are backed by a written warranty covering movement caused by frost for the lifetime of the piles - a miminum of 75 years in the harshest environments.

Ask your local installer for full warranty terms before work begins.
