Hot-dipped galvanized iron helical screw piles

Helical piers are used for new construction and to support existing structures. They are designed for applications in expansive soils, high water tables, fill areas, and other areas where unstable soils require a deep foundation. In compression they are used as footers and in tension they may be used to support retaining or foundation walls. Helical piers are round or square, tubular or bar steel shafts with round helix plates welded to them.
