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.

Square Shaft Advantages:

• Greater yield and Tensile strength
• Patented Cross-bolt Connection
• Increased safety factor
• Higher torque capacity
• Easy to install
• Installs in any season
• Minimal soil disturbance
• Not affected by a high water table

Composition:

• 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

A helical pile is an end-bearing deep foundation system with compression and tension applications. Applying torque to the shaft installs the helical pile with no vibration, no spoils and minimal disturbance.  Loads are transferred down the shaft onto the helical plates to the load-bearing strata above and beneath each helical plate. The torque required to install the helical pile correlates to its capacity - the greater the resistance (torque), the denser the soil, and the higher the load-carrying capabilities.

Application

New Construction

Helical piles are excellent for new construction in tension or compression to support a variety of structures ranging from industrial, commercial, institutional, infrastructure and residential applications from one to thirty stories.

Retrofit

Well adapted to the challenges that occur in retrofit applications helical piles are great for adding more capacity to an existing foundation for repairs, remediation or renovation.  

Tower Support

From communications to transmisson towers helical piles can be installed in low headroom and in remote areas with difficult access. From new installations to adding capacity to existing structures for new loads helical piles offer flexibility and accessibility.

Slope Stabilization

In areas where traditional slope stabilization methods are not practical or feasible, helical piles offer an option that tackles access challenges and timing.
