The SeaShield FX-70™ System 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.

Surface Preparation

  • Dry Abrasive Blast Cleaning Not Essential


The SeaShield FX-70 pile repair and protection system was the first in-place repair solution for damaged concrete, steel, and wood piles when it launched in 1970, and many of those first repairs remain in service today.

The SeaShield FX-70 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. 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.
