Helical piers and anchors are end bearing foundation elements, meaning the load is transferred down the solid square steel shaft into the helical bearing plates and into the load bearing soil. By applying torque to the shaft, the helices penetrate the soil by minimally displacing the soil on either side of the helices. The friction that is created between the helical plates and the soil during installation requires torque to install it into the soil. The torque that it takes to install the screw anchor is measured and correlates directly back to the capacity of the pier. For more information on the theory of how helical piers work.
