Auger Cast Piling

Auger cast piles also known as continuous flight auger piles or CFA are installed by rotating a continuously flighted hollow shaft auger into the soil. Other variations include drilled, displacement piles. High strength cement grout is pumped under pressure through the shaft as the auger is slowly withdrawn. Grout takes and pumping pressure is continuously monitored as the augers are withdrawn. Reinforcing steel is added once the augers are removed. Auger cast piles can be a cost effective foundation method in the right soil conditions.
