Foundation Support Using Helical Piers.
Helical piers in New England are used to support existing structures as well as to provide support for new construction. In compression they are used as footers and in tension they may be used to support retaining or foundation walls. Helical piers are essentially a large screw that is drilled into the earth to a specified depth by using a hydraulic motor on the back of a backhoe or skid steer. It’s a fast and easy way to install a foundation system. For all your helical piers Massachusetts needs, count on Atlas Systems of N.E.
Helical Piles:
A helical pile is a deep foundation support system used to support or resists any load or application in either compression (down), tension (up) or lateral (side). The helical pier is comprised of three elements. The pile is installed applying a torsion force to the pier via a hydraulic motor. The torque applied during installation when applied to an empirical conversion factor typically indicates ultimate capacity.
Starter Section
Comprising of at least one bearing plate to transfer the loads to the bearing stratum from the surface.
Extensions
Comprising of a steel central shaft transmitting the torque to the bearing stratum.
Termination
Comprising of interface between the structure and the helical pier.
