Augercast Piles

Augercast piles are smaller diameter, cast-in-place deep foundation elements. They can vary in diameter from 12 to 48 inches and are most efficient in granular or incohesive soil and/or high water tables. Augercast piles can be installed quickly with minimal disturbance in noise and vibration. They can be designed as end-bearing, friction or a combination of both depending on the soil properties and proximity to rock. Augercast piles are installed by rotating a hollow stem, continuous flight auger into the earth to the designed depth. Structural grout is then pumped through the hollow stem as the auger is slowly withdrawn. Once the hole is pumped full of grout, reinforcement can be placed.
