Helical pile systems are factory manufactured and designed to reach competent, load-bearing soil deep beneath the foundation. Generally, they consist of a central shaft, helix blades, and extension shafts to ensure proper depth and capacity are reached. But when the surrounding soils are loose, soft, or fluid, modifications to the typical helical pile design may be necessary to avoid buckling of the system.
The Supportworks Helicast™ Grouted Helical Pile System has several benefits over other solutions to address buckling concerns. TC Hafford Basement Systems is a professional installer of the Helicast™ System for commercial applications in Portland, Bangor, Rochester and nearby.

The Helicast™ Grouted Helical Pile System utilizes a traditional lead solid square shaft with lead displacement plates, also known as helix blades. The plates are located at the coupler locations for each extension shaft, allowing soil to be pushed away while the system is advanced as far into the ground as necessary.
Grout is simultaneously poured to fill the hole created by the helical pile system, which creates a uniform grout column because of the even disbursement of identical displacement plates. The grout reservoir gives needed stability to the entire system when surrounding soils are not a sufficient anchor.
The grout reservoir surrounding the Helicast™ pile gives this system its signature stability.
In certain applications, the addition of a grout column and the use of the Helicast™ system can yield several benefits for deep foundations:
