The Continuous Flight Auger (CFA) process is virtually vibration free and one of the quietest forms of piling, making it ideal for areas where noise is a concern. It also allows boring in especially wet ground and is suitable for gravels, sands silts, clays, soft rocks, and mixtures of the preceding types.
The piles are constructed by drilling to the required depth using a hollow stem continuous flight auger. After reaching the designed depth, concrete is then pumped through the hollow stem. While the concrete is being poured into the stem, the auger is withdrawn removing the soil, and insuring a consistent consistency of concrete throughout the shaft.
A reinforcing cage is then inserted into the liquid concrete to insure maximum strength.
