A Helical Pier can be thought of as a large screw, which is driven into the ground. It provides stability to the foundation, acting like an anchor. In fact, they are also known in the industry as anchors, piles, and screwpiles. They provide deep foundation solutions for both new construction, and to repair an existing foundation.
When soil conditions prevent the use of standard foundation solutions, helical piers are often used because of their design and ease of installation. Rather than excavation, which can be both costly and time consuming, the piers are threaded into the ground. The resulting process reduces installation time and soil disturbance while properly transferring the weight of the structure to stable, load-bearing soil.
