Shaft Foundations

Drilled shafts, also referred to as drilled piers or bored piles, are used to support structures with large axial and lateral loads. They are constructed by excavating cylindrical shafts into the ground, placing a reinforcing cage (when necessary) and are subsequently filled with concrete or other pre-fabricated load-bearing units.
