Understanding continuous flight auger piling

CFA piling, or continuous flight auger piling, is a bored cast in-situ pile installation method in which a continuous flight auger with a hollow central stem is rotated into the ground to the design depth in a single uninterrupted pass. Once at depth, a structural concrete mix is pumped under pressure through the hollow stem as the auger is withdrawn at a controlled rate, filling the bore from the bottom upwards. A prefabricated steel reinforcement cage is then installed into the fresh concrete to form the completed structural pile.

It is one of the most widely specified piling methods in the UK for both residential and commercial construction, offering a reliable combination of speed, structural performance, and minimal disruption to the surrounding environment.
