SERVICES – AUGERCAST PILES

Augercast Piles are deep foundation elements installed by rotating a continuously-flighted hollow stem auger into the soil to a specified depth. Concrete or grout is pumped under pressure through the hollow shaft as the auger is withdrawn, resulting in a pile element that can be built in unstable soils and beneath the water table.

The auger is rotated clockwise during withdrawal, which promotes migration of soil up the auger flights and ensures a continuous uncontaminated grout or concrete column. Steel reinforcing to aid in resisting lateral and tension forces is installed after the auger is withdrawn and while the concrete or grout is still fluid. The resulting concrete or grout column cures and forms an augercast pile.

Augercast piles can be installed diameters ranging from twelve inches (12ins) to forty-two inches (42ins).
