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 stem pipe, commonly referred to as round shaft or pipe piles – with helical plates welded to it. These are segmented, extendable shafts in 3′, 5′, 7′, and 10′ increments. In most applications, only the lead or first section has helical plates while plain extensions (pipe or solid square bar) are added to reach competent load-bearing soil strata.
Tension vs. Compression
The industry refers to helicals in tension (tiebacks, tiedowns, soil screws, etc.) as anchors and they are almost always square shafts.
Helicals in compression (foundations) are referred to as piles or piers. They can be either pipe or square shaft. Pipe piles are a good choice in soft soils, while square shaft better fight through sand, harder layers, trash, and obstructions.
