Continuous flight Auger

The Continuous Flight Auger (CFA) is a specialized drilling method used in construction and geotechnical engineering. It involves a continuous helical flighted auger that is rotated into the ground while concrete or grout is pumped through the hollow stem of the auger. This process creates a continuous column of soil or rock spoil above the auger as it is slowly extracted. The CFA technique offers several advantages, including efficient drilling, minimal noise and vibration, and the ability to construct deep, high-capacity piles or foundations in various soil conditions. It is widely used in building projects and infrastructure development.
