When your home or commercial structure is resting on unstable soil, there are many ways of remedying this, and helical piering is one of the most effective remedies for foundation failure.
Helical piering, also known as helical piling, is the process of inserting helix-like screws into the ground below the unstable soil, using a hydraulic drill attached to an excavator. The helical piers are driven into the earth until the necessary load capacity for the structure is achieved. These screws are then attached to the base of your structure, so that its movement is restricted. Brackets are then fastened to the base of the foundation walls, which transfers the weight of the building to the helical piers.
