Augercast piles are installed using a continuous flight auger, advanced into the soil by means of a hydraulic drill. This drill can be a self-contained unit or mounted in a prefabricated set of leads.
The auger is drilled to the desired tip elevation or refusal where the grouting process begins. Grout is injected through the bottom port of the hollow stem auger, replacing the soil removed by the drilling operation.
The pile is then grouted to grade and set to the correct cut-off elevation. Reinforcing may be placed into the fluid grout. These piles range in diameter from 12 to 36 inches. Soil conditions and structural components of the pile dictate capacities.
