Simpson-Strongtie: FX70 Structural Repair & Protection Systems

FX70 Structural Repair & Protection Systems

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 & general weathering are all examples of factors affecting the lifecycle of structures in marine environments addressed by the FX-70® Structural Repair & Protection System.


To protect the structure from external attack, the FX-70 Structural Repair and Protection System starts with a high-strength fiberglass interlocking jacket. The tongue-and-groove seamed jacket provides a corrosion-resistant shell to the repair site, ranges from 1/8 in. to 1/2 in. thickness, and is UV-resistant.

High-Strength Grouting Materials

FX-70- 6MP™ Multi-Purpose Marine Epoxy Grout & 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 & other common building materials. These products displace existing water & 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, & is commonly combined with FX-225 to reduce material cost on large jobs or to repair structures with greater than 25% section loss.
