FX-70 Fiberglass Jacket

Each FX-70 high-strength fiberglass interlocking jacket is custom-made to the precise specifications of the repair project. Hand-made and assembled in the U.S., the FX-70 tongue-and-groove seamed jacket provides a corrosion-resistant protective shell and is available in round, square, H-pile and octagonal shapes. Panels and custom shapes are also available for additional applications such as pile foundations and seawalls.

High-Strength Grouting Materials

FX-70-6MP™ Multi-Purpose Marine Epoxy Grout and FX-225 Non-Shrink Non-Metallic Underwater Grout are both high-strength, water-insensitive repair compounds. FX-70-6 MP provides excellent bond to concrete, steel, wood and other common building materials. These products displace existing water and can easily be placed into the FX-70 jacket without the costly building of cofferdams or dewatering of the repair site. FX-70-6 MP is ideal for repairs to structures with less than 25% section loss, and is commonly combined with FX-225 to reduce material cost on large jobs or to repair structures with greater than 25% section loss.
