Helical piles are deep foundation elements constructed using steel shafts with single, double or triple helical flights.
- Support structures
- Reinforce foundations
The shafts of the helical piles (also referred to as helical piers) are screwed into the soil to design depth while the torque is being monitored to evaluate pile capacity. A thorough knowledge of subsurface conditions is essential to properly understand the torque conversion. Once design capacity is reached, the shaft tops are cut and capped to be incorporated into the foundation system. This technique has been used to support lightly loaded structures, pipe supports, tanks, modules, process equipment, transmission lines, and modular work camps.
