  • 1.75" SQR Shaft - 1 product with 28 Ton allowable capacity
  • 2.875" O.D. Round Shaft - 1 product with 11 Ton allowable capacity
  • 3" O.D. Round Shaft - 4 products ranging from 8 Ton to 25 Ton allowable capacity
  • 4.5" O.D. Round Shaft - 4 products ranging from 35 Ton to 46 Ton allowable capacity
  • 5.5" O.D. Round Shaft - 2 products ranging from 62 Ton to 98 Ton allowable capacity
  • 5.72" O.D. Round Shaft - 6 products ranging from 46 Ton to 92 Ton allowable capacity
  • 8.63" O.D. Round Shaft - 2 products ranging from 66 Ton to 132 Ton allowable capacity

(see ProductSpecifications for detailed information)

There are many applications for the Magnum Helical Piles including:

  • Deep Foundation Piles for New Construction
  • Concrete-Less Foundations for Light Construction
  • Concrete Slab Lifting & Stabilization
  • Temporary & Permanent Shoring
  • Underpinning Commercial & Residential Structures
  • Tiebacks & Wall Anchors
  • Earth Anchors for Slope Stabilization
  • Temporary & Reusable Tilt-Up Wall Anchors
  • Boardwalks & Pedestrian Bridges
  • Sea Walls & Bulkheads
  • Pipeline & Utility Tie Downs
Helical piles have significant load bearing capacity and are used in both compression (downward) and tension (uplift) applications. When a helical pier is installed into suitable soil, the load of the structure is transferred to the bearing plates welded to the shaft.

 The primary benefits of Magnum Helical Piles (helical anchors, screw piles) are:

  • Fast Installation – 20 to 100+ a day (depending upon depth) with a single installation device & a 2 to 3 man crew
  • Pre-Engineered System – capacity-to-torque ratio produces very predictable installation results
  • Variety of Piles & Capacities – allowable working capacities ranging from 8 tons to 130+ tons; wide selection of products to match capacity requirement
  • No Soil Spoils – eliminates spoil removal costs; good solution for environmentally contaminated sites
  • Small Maneuverable Installation Equipment – minimal equipment costs; no vibration; limited disturbance to sensitive sites
  • Dual Cutting Edge Helix – patented design enables superior pier installation through occasional cobbles, tightly compacted clay soils, weathered bedrock, & dense fill materials
  • Single Bolt Connection for 3" Product Line – for fast & efficient installation
  • Reinforced Dual-Sleeve Connector – for higher installation torque and capacity; protects against bolt hole elongation making installation easier
Magnum installers have installed our helical piles across the planet from the Bahamas to Alaska, mountains to lowlands, in every state within the U.S., every Canadian province, and many countries in Europe.

Patent # 6,058,662
Magnum® Dual Cutting Edge (DCE) Blade™
This revolutionary patented blade design enables Magnum Helical Piles to penetrate difficult soils including very dense gravel, soils laden with occasional cobbles and even fill soils containing trash like trees, concrete debris, small to medium rocks, etc.

The patented DCE Blade can even penetrate sedimentary bedrock with standard penetration test (SPT) blow counts of up to 50 blows for 6 inches.

Read what Magnum installers are saying about the Magnum DCE Blade.

Mr. Joe Loudermilk
Partner – Extreme Technology’s, Atlanta, GA
“Magnum’s Helical Piles with the DCE Blade are the best helical piles I’ve ever installed. The blade design virtually eliminates any side-to-side (wobble) motion and the piers advance in our dense clay soils just like a screw into wood.”

Mr. Ross Kirk
Owner – Marco Concrete Lifting, Charleston, WV
“Hands down the best blade design for penetrating our dense West Virginia clay soils. The Magnum DCE blade even allows us to penetrate our shale formations without deflection or failure. The DCE blades are great!”

Mr. Jerry Lipe
Owner – Lipe Brothers Construction, Duluth, MN
“Our crews specify the Magnum DCE blades for our helical piles because the blade is able to penetrate the Laurentian Shield formations in our region. Often times we encounter these layers at very shallow depths, and the DCE blades will cut through it so we can get below frost depths and into good tight clays."
