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”
