Helical Pier

 

Helical Pier

Advance Concept (formerly KTM)  is proud to be a certified Pier Tech Systems installer.  We chose Pier Tech because they are the only company to make round rods which are better in compression.  They also have square , which are better in tension.  Pier Tech is also the only company to make large rods, giving us more diversity.

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”.

Square Shaft Advantages:

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

The Helical Anchor consists of:

  • 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”
