CFA drilling refers to Continuous Flight Auger drilling, a fast and economical foundation piling method where a continuous flight auger is drilled into the ground to a specific depth. While drilling, soil is conveyed to the surface. Once the required depth is reached, concrete is pumped through the hollow stem of the auger as it is simultaneously and slowly extracted, filling the borehole to form a pile. This process is often monitored electronically to ensure quality and can be done in a single pass.
