CONTINUOUS FLIGHT AUGER (CFA) PILE

pile shaft will be formed. If it is too slow, there will be a pressure build-up which forces grout up the sides of the auger, and can lead to the flight becoming stuck. D. The steel reinforcing cage is lowered into the wet concrete/grout in the pile shaft until it is at the correct level. This completes the installation sequence. CONTINUOUS CONTINUOUS FLIGHT AUGER (CFA) PILESThe pile is formed by first drilling into the ground with a continuous flight auger. Cement-sand grout or concrete is then injected under pressure through the augers hollow stem as it is being withdrawn. The grout or concrete pressure is maintained during the auger withdrawal so that it assists the extraction as well as exerting a lateral
