Augercast piling also commonly known as CFA piling, auger cast piling, cast in place piling or augered piling are formed by advancing a continuous rotating auger to the full pile depth, and then pumping cementitious grout through the auger's hollow stem as the auger is slowly withdrawn. The soil surrounding the drilled hole becomes the "form" for the pile.

A pre-tied steel reinforcing cage is then lowered into the fluid grout to form a reinforced cast-in-place concrete piling.
