Attack of structures at the waterline is commonplace in marine environments. Tidal action, river current, salt water exposure, chemical intrusion, floating debris, marine borers, electrolysis and general weathering are all examples of factors affecting the lifecycle of structures in marine environments addressed by the FX-70® Structural Repair and Protection System.

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.
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.
