Helical piles are hollow steel tubes that are used to stabilize structures by anchoring the load to the surrounding ground, much like a driven pile. However, helical piles are screwed deeply into the earth, section by section if necessary. They are screwed into the ground until it’s proven that the area can properly hold the required bearing capacity of the structure.
Helical piles can be used to create new foundations, to underpin weakening foundations, and to better stabilize existing foundations in preparation for heavier loads.
What is the benefit of using helical piles versus driven piles?
According to the Helical Pile Association, a foundation created using helical piles is preferred over driven piles, drilled shafts, grouted tendons, auger-cast piles, belled piers and other deep foundation systems for a number of reasons:
1. Quicker, cleaner installation
2. Can be loaded immediately
3. Elimination of high-mobilization costs associated with driven piles, drilled shafts or auger cast piles
4. Instant torque-to-capacity feedback for production control
5. Easier modification while in the field
6. Higher efficiency in limited access sites, high water tables, and weak surface soils
7. Equipment can be easily fitted with hydraulically-driven torque motors with helical pile installation
