Helical piles, also known as helical piers, are deep foundation underpinning elements constructed using steel shafts with helical flights. The shafts are advanced to bearing depth by turning them into the soil while monitoring torque to calculate the pile capacity.
Helical piles do not excavate or create spoils that need to be removed, and loads can be immediately applied. You can install them in any weather condition, as well as in limited access areas.
