Drilled Shafts
Support structures with large axial and lateral loads
Drilled shafts, also referred to as drilled piers, caissons or bored piles, are deep foundation solutions used to support structures with large axial and lateral loads by excavating cylindrical shafts into the ground and filling them with concrete.
Drilled shafts are typically designed and constructed to support axial forces through a combination of side friction and end bearing resistance. They range in diameter from 24” to 120” and can be installed to depths in excess of 300 feet.
Drilled shafts are an economic solution that can be installed in a variety of different ground conditions to accommodate large axial, lateral and overturning forces.
