Auger cast piles are installed by rotating a continuously flighted hollow shaft auger into the soil to a specified depth. High strength cement grout is pumped under pressure through the shaft as the auger is slowly withdrawn. Reinforcing steel is added per pile specifications. An auger cast pile is both end-bearing and friction-based. Pile diameters of 12” to 18” are typical, but larger piles are available.
