Helical Piles

The shafts are advanced to bearing depth by twisting them into the soil while monitoring torque to estimate the pile capacity.

The helical pile system is a deep foundation system that consists of helical bearing plates around a central shaft. They are advanced to bearing depth by being screwed in the soil with minimal disturbance. By monitoring the torque necessary to install them, the pile capacity can also be estimated. Once installed the loads from the superstructure are transferred from the pile to the soil through the helical bearing plates.
