What Are Helical Piers?

A helical pier (also called a helical anchor, helical pile, screw pile, screw anchor) is an adjustable deep foundation system with helical bearing plates welded to a central steel shaft.

The weight of the structure is transferred from the shaft to the soil through these bearing plates. Screw piles are manufactured using varying sizes of tubular hollow sections for the pile or anchors shaft.

This will allow the weight of the structure to be transferred from unstable or weak soil, to stable soil or bedrock. Helical piers can also be used to anchor buildings or structures to the ground. Commonly used in residential and commercial foundation repair.

Residential and Commercial Applications

Helical piers are used in several popular applications including:

  • Basement Wall Tieback - for bowing and leaning walls
  • New Construction - to add support from the start for new building projects, residential and commercial
  • Foundation Repair - for lighter weight structural problems caused by settlement or sinking foundations
  • Shoring - for retaining walls and other wall that need extra support
  • Soil Nails - helical piers are used in conjunction with soil nails for sloped areas
  • Slab Repair - helical piers can add lift and stability for sunken slabs

The pile shaft transfers a structure's load into the pile. Helical steel plates are welded to the pile shaft in accordance with the intended ground conditions. Helices can be press-formed to a specified pitch or simply consist of flat plates welded at a specified pitch to the pile's shaft.

Advantages Of Helical Piers

Most industries use screw pile foundations due to the cost efficiencies and the reduced environmental impact. 'Screwing' the foundations in the ground means that there is less soil displacement so excess soil does not need to be transported from the site, saving on transportation costs, and reducing the carbon footprint of the project.
