Auger/drilled piles are a method of piling used when the ground conditions are such that a steel cased driven pile would be unsuitable. We predominantly install these auger piles into clays/rock. The mini piling rig bores into the ground and on retraction of the auger, the bore is filled with concrete/cementitious grout and reinforcement, forming the augered pile.
Auger piles cause minimal disturbance and can be used for noise-sensitive sites. Auger piles are not generally suited for use in contaminated soils, because of expensive waste disposal costs.
