Augercast Pile Installation

Augercast Pile Installation

Augercast piles are high-capacity deep foundations best suited for sands and silts below the water table. They install by drilling a continuous flight, hollow stem auger to the termination depth. A sacrificial plug inserts into the auger tip prior to construction and is pushed out by grout flow.

After reaching design depth, grout pumps through the auger as the auger is slowly removed (with rotation) from the hole. Upon completion of the pile, a steel cage or single steel bar may be placed in the center of the hole in the still-fluid grout in order to provide reinforcement.
