Helical Pier Specifications

 

 

THE TWO TYPES OF HELICAL PIERS

Round shaft, best used in compression situations, and square shaft best used in tension situations.

The Best in the Industry

  • Made from the highest quality steel
  • Higher torque capacity than the competition
  • Superior lateral strength and stability
  • Galvanized or bare steel options
  • Square or round shafts

 

ROUND SHAFT HELICAL PILES

In applications where compression is the primary consideration we recommend using round shaft piers. In Compression our round shaft  has several advantages over the typical square shaft.

Features at a Glance

  • Best for compression forces
  • Easy to install
  • Installs in any season
  • Minimal soil disturbance
  • Not effected by high water table
  • Installed with lightweight portable equipment

Round Shaft Advantages

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

Composition:

  • 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”.
  • Galvanized or bare steel options available

SQUARE SHAFT HELICAL PILES

In applications where tension is the primary consideration we recommend the Square Shaft Piers. They have several advantages over the typical square shaft anchors.

Features at a Glance

  • Best for tension forces
  • Easy to install
  • Installs in any season
  • Minimal soil disturbance
  • Not effected by high water table
  • Installed with lightweight portable equipment

Square Shaft Advantages:

  • Greater Yield and Tensile Strength
  • Patented Cross- Bolt Connection
  • Increased Safety Factor
  • Higher Torque Capacity

Composition:

  • A square solid shaft 1 ¼” thru 2” 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”
  • Galvanized or bare steel options available
 

How Do They Work?

The helical screwpile is screwed into the soil until a desirable load capacity has been achieved, and then spaced at intervals pre-calculated to spread the load of the structure. In foundation repair applications, brackets are then attached to the foundation wall bases and weight is transferred to the pile.
