Helical Piers, Helical Piles and Helical Anchors: PierTech® Helical Piering Systems

The PierTech® Round Shaft Helical Pier

We Recommend Round Shaft In Compression

In applications where Compression is the primary consideration we recommend the PierTech Round Shaft Helical Pier. In Compression our round shaft helical has several advantages over the typical square shaft helical anchor.

PierTech Helical Piers


PierTech Helical Pier Installation

Round Shaft Advantages:

  • Superior Lateral Stability
  • Greater Section Modulus Strength to resist Twisting and Deflection
  • Patented Cross- Bolt Connection
  • Greater Load Capacities



The Helical Pier consists of:

  • A round hollow shaft 2 7/8” thru 12 ¾” O.D. typical.
  • Circular tapered plates (helices) are welded to the center of the shaft.
  • Helix diameters can range between 6” - 48” with a thickness of 3/8” – 1”.
  • Helix pitch will range from 3” – 6”.



The PierTech® Square Shaft Helical Anchor

We Recommend Square Shaft In Tension

In applications where tension is the primary consideration we recommend the Pier Tech Square Shaft Helical Anchor. The Pier Tech Square Shaft Helical Anchor has several advantages over the typical square shaft helical anchor.
