Commercial Helical Pile Installation

Helical piles, also referred to as helical piers, resemble large steel screws that are advanced into the ground on a drive head attached to a backhoe or skid steer. The steel pile is drilled into the ground like a corkscrew. Soil torque is monitored every step of the way and actually increases the deeper the pile goes. Installers use a gauge attached to the drive head to keep track of the soil torque. They need to reach an exact level and torque to ensure foundation stability.
