SeaShield Series FX-70

The SeaShield Series FX-70® features custom-made tongue-and-groove seamed fiberglass jackets that provide a corrosion-resistant protective shell for the life of the repair. High-strength, water-insensitive repair grouts and mortars are used to strengthen and protect damaged piles. These products displace existing water and can be easily pumped, tremied or poured into the SeaShield FX-70 jacket even while it is submerged in water.

The SeaShield Series FX-70 pile 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 repair is executed.
