What are the advantages of a Helical Pier?
A. Helical Piers are true end-bearing piers. The weight of the structure is transferred to the helical plates. Helical Piers are installed independent of the structure and do not rely on the weight of the structure for installation. This prevents shaking or moving of the structure. Helical Piers are installed to a known capacity and a known competency of soil. This means that the helical pier can be installed with a factor of safety (most often 2 times the dead and live loads of the structure) and terminated in a soil strata or bedrock capable of supporting the load. Unfortunately, push piles cannot do this unless they are resting on rock.
