Auger-Cast Piles

Auger-cast 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 Concrete or grout is pumped under pressure through the hollow shaft as the auger is withdrawn, resulting in a pile element that can be built in unstable soils and beneath the water table.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.
