Helical Piles

Helical piles are a factory-manufactured steel foundation system consisting of a central shaft with one or more helix-shaped bearing plates and a bracket that allows attachment to a structure.  The helix plates are commonly referred to as blades or flights and are welded to the lead section. 

Helical Piles

Extension shafts, with or without additional helix plates, are used to extend the pile to competent load bearing soil 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 are advanced (screwed) into the ground with the application of torque.

The terms helical piles, screw piles, helical piers, helical anchors, helix piers, and helix anchors are often used interchangeably by specifiers.  However, the term “pier” more often refers to a helical pile loaded in axial compression, while the term “anchor” more often refers to a helical pile loaded in axial tension. The term “pile” traditionally describes a deep foundation that can resist both tension and compression loads.
