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.
how they work:
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.
why you need them:
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.
