Continuous Flight Auger Piling
Continuous Flight Auger Bored Piles (CFA Piling) are constructed with a string of hollow stemmed augers fixed to the piling rig. Once the depth has been reached, concrete is pumped through the centre of the augers to base of the pile. The augers are then extracted whilst the concreting continues to ground level, reinforcement is introduced completing the pile. As cfa piling contractors this offers a system ideal for wet ground, sand and gravels.
