Sectional Flight Auger Piling
Sectional Flight Auger piles are used by mini piling contractors. They use hollow stemmed augers that are added to the rig as each meter enters the ground. Once the depth has been reached, grout/concrete is pumped through the centre of the augers to base of the pile. The augers are then extracted whilst the grouting continues to ground level, reinforcement is introduced completing the pile. This method of piling alleviates any issues with unstable bores and water strikes as the bore is permanent supported by the augers throughout construction. Ideal when access is restricted.
