Helical piles are an end-bearing deep foundation system that has applications in both compression and tension. By applying torque to the shaft this action installs the helical pile with minimal displacement or disturbance. No vibrations or spoils are created during installation. Loads are transferred down the shaft onto the helical plates and into the minimally disturbed load bearing soil beneath or above each helical plate. The resistance required to torque the helical pile into the soil directly correlates to its capacity – the greater the resistance (torque) the denser the soil and the higher the load carrying capabilities. It is a fast and lightweight method that is approved by national building code agencies, and is the deep foundation system of choice for architects, builders, and engineers alike.

Advantages of Helical Piles

  • Eliminates high-mobilization costs that are associated with driven piles, drilled shafts or auger-cast piles
  • Immediate torque-to-capacity feedback for production control
  • Minimizes soil disturbance during installation
  • Uses common construction equipment easily fitted with hydraulically-driven torque motors
  • No excavation, vibrations or spoils
  • Quick installation when compared to traditional deep foundation solutions
  • Can be loaded immediately upon completion
  • Approved for use by building code agencies
  • Easy to use in limited access areas, areas with high water tables, and weak surface soils
  • Can be modified in the field
  • Capacities up to 210 kips ULT
  • Predictable load capacities
  • Installation in environmentally sensitive areas
