FX-70® Structural Piling Repair and Protection System for Timber, Concrete and Steel Piles

The FX-70 structural piling repair and protection system was the first in-place repair solution for damaged concrete, steel and wood piles when it debuted in 1970, and many of those first repairs remain in service today. By eliminating the need to dewater the site or build cofferdams, the FX-70 system drastically reduces the overall expense and loss-of-use cost as the structure can generally remain in service while the pile repair is executed.
