deep foundations

Deep foundations are construction methods used to support structures when shallow soils are not strong enough to hold the load. They involve extending foundations deep into the ground to reach more stable soil or rock layers that can safely carry the building’s weight. Common types include piling, where long columns are driven into the ground, and drilled shafts, which are large, drilled-out cylinders filled with concrete. These foundations ensure stability, safety, and durability for tall buildings, bridges, and large infrastructure by transferring loads to deeper, stronger soil layers.
