SERVICES | Continuous Flight Auger (CFA) Piles

CFA piles are constructed by utilizing specialized drilling equipment and methods developed, in part, by Scheffler. The CFA pile is constructed by drilling a hollow-stem auger into the ground to final depth in a single operation. Once at depth, concrete is pumped through the auger’s stem, filling the hole as the auger is extracted. After the concrete is placed, steel reinforcement, either an I-beam or a reinforcing cage, is placed into the fluid concrete column. Advanced computer instrumentation monitors all aspects of pile placement including: depth, speed of auger rotation, rate of advancement, torque, concrete head pressure, and volume of concrete placed. CFA piles can be constructed in diameters ranging from 16 – 48 inches, and up to 80 feet deep. They are extremely cost effective and can dramatically reduce the time it takes to construct a typical drilled foundation.
