Square shafts consist of solid square sections ranging from 1.5 inches to 2 inches in size. These piles are primarily designed for ultimate loads between 100 and 650 kN (25-150 kips), although they have been tested to withstand loads exceeding 900 kN (200 kips) in specific circumstances.
Square shaft piles are typically utilized in small to moderate loading applications and offer excellent resistance to tension. They are particularly effective in penetrating dense and cobble-rich soil compared to their helical pipe pile counterparts. However, they exhibit lower resistance to buckling and provide minimal lateral load resistance.
In scenarios where tension is the primary concern, Square Shaft Piers are highly recommended. These piers offer several advantages over standard square shaft anchors, including enhanced stability and greater load-bearing capacity. Their design allows for more efficient installation and better performance in challenging soil conditions, making them a superior choice for applications requiring robust tension support.

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:
Composition:
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.
