The "Continuous Flighter Auger" or CFA pile is an auger bored 'replacement' pile with soil extraction and pumping of concrete under pressure. The pile is formed by means of a helical screw (auger) with a hollow stem bored into the ground to design depth. Concreting is achieved by pumping fluid concrete through the hollow stem of the auger, delivering concrete to the bottom of the pile bore. Pile arisings are brought to the surface during drilling and concreting phase.
