Auger Cast piles are installed by rotating a continuously flighted hollow shaft auger (CFA) of approximately 12” to 36” in diameter to soil depths of up to 100’. High strength cement grout is pumped under pressure through the shaft as the auger is slowly withdrawn. Reinforcing steel placement occurs immediately after the auger is withdrawn and extends into the concrete cap. Auger Cast Piles are best suited for Deep Foundation elements, Cantilevered Shoring and Tie-back Shoring.
