Continuous Flight Auger (CFA)
Piling is the quietest form of piling and is a fast and very economical technique. It is a cast in-situ process, very suited to soft ground where deep casings or use of drilling support fluids might otherwise be needed. CFA piling is a non displacement piling system; hence the soil excavated from the pile is brought to the surface. CFA piles can be an attractive alternative to conventional bored piles (faster installation) and to driven piles (much less noise and vibration).
