Helical piles, also known as anchors, piers or screw piles, are steel deep foundation solutions used to secure new or repair existing foundations. Consisting of a extension shaft with one or more helix-shaped bearing plates, commonly referred to as blades or flights, welded to the lead section.

Extension shafts, with or without additional helix blades, are used to extend the pile to competent load-bearing soils and to achieve design depth and capacity. 

Brackets are used at the tops of the piles for attachment to structures, either for new construction or retrofit applications.

Helical piles have been used all over the world to secure residential and commercial buildings.Helical piles are installed at intervals between the footing forms and tied into the rebar grid work prior to pouring concrete. The piles are extended to depths attaining the installing torque that correlates with the required load bearing capacity.
