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 piers are installed by advancing an auger/drill tool to the required depth using open hole, casing, or slurry techniques. Once the desired tip elevation has been achieved, the drilled pier reinforcement is set in place and the drilled shaft is filled with concrete. Drilled piers are effective in a variety of soil conditions and Greenbridge Construction is your drilled pier expert in Maryland, DC Metro, Virginia and Pennsylvania.
