The SEASHIELD FX-70™ SYSTEM is a permanent, engineered repair and protection system designed for restoring and reinforcing damaged concrete, steel, and timber piles below the waterline—without the need for dewatering or cofferdams. It utilizes a prefabricated fiberglass-reinforced jacket combined with FX-70™ structural underwater epoxy grout to provide structural reinforcement and corrosion protection.

Developed originally by Simpson Strong-Tie, the FX-70™ system has become a trusted solution in marine infrastructure rehabilitation due to its ease of application underwater, exceptional bonding strength, and proven long-term performance in aggressive saltwater environments.

The system is ideal for use on piles in ports, bridges, piers, and offshore structures where full or partial deterioration has occurred in splash zones, tidal areas, or submerged conditions.
