Our Solution

CFA (continuous flight auger) piles are drilled and concreted in a single continuous operation, which allows a much faster installation process than bored piles. Reinforcement is added into wet concrete after casting which permits the pile to withstand the full range of structural loading. The process of CFA piling involves rotating a hollow stem continuous flight auger into the soil, to a certain depth, before concrete is then pumped through the hollow stem to fill the cylindrical cavity made by the auger, as the auger is gradually removed. The reinforcement cage is then set down through the freshly placed concrete.

CFA Uses

Common uses of CFA piles are: To provide structural support Prevent landslides and protect buildings already there. As well as providing earth retention Infrastructure projects - tunnelling, road/bridge construction.
