In addition, they are also referred to as CFA (continuous flight augering) and are the most efficient in in-cohesive and granular soil or high water tables. Auger cast are cast in-place with the application of a continuous flight auger with a form of a hollow at the center to receive liquid cement before the auger is pulled out.
Compared to driven piles techniques, auger cast piles are environmentally-sensitive with minimal noise and vibration. They are firmer than prefabricated piles due to the additional soil friction around the piles from in-place casting. These and many other benefits that made auger cast piles more preferable to other techniques of soil reinforcement will be spoken about in upcoming posts.
