Auger Cast piles or Continuous Flight Auger (CFA) piles are created by rotating a continuous flight auger into the ground to a specified depth and then slowly withdrawing the auger while pumping cementitious grout under pressure to create the pile as the auger is retracted. As the auger is retracted, the spoils on the auger are continuously removed by a small excavator or loader. Once the pile has been grouted and auger completely removed from the pile, reinforcing cages may then be wet set into the previously placed concrete.
The quality of the auger cast pile is largely dependent on the skill and experience of the contractor performing the work. Condon-Johnson & Associates is continuously selected for auger cast pile installation due to our vast experience and positive reviews from designers, contractors, and owners after the project is completed.
