Helical Piles, Piers, and Anchors 

A helical pile, also known as a helical pier, helical anchor, screw pile, or screw anchor, consists of a shaft – either a solid square bar or a hollow tubular – with helical plates welded to it. These are normally segmented shafts ranging in length from 5’ to 10′. In most applications, only the lead or first section has helical plates while plain extensions are added to reach competent load-bearing soil strata.

Compression vs. Tension

Helical installations in compression (foundations) are referred to as piles or piers. They can be either square shaft or round. Tubular piles have become the standard helical pile.

The industry refers to helical installations in tension (tiebacks, tiedowns, soil screws, etc.) as anchors and they are almost always solid square shafts.

We offer an extensive inventory of the highest quality and most cost-effective high strength helical piles, piers, and anchors on the market today for all applications, soil conditions, load bearings, and more.
