Simpson Strong-Tie has introduced the FX-70-6FS fast-set epoxy bottom seal, a three-component epoxy grout designed as part of the FX-70 structural repair and protection system to facilitate same-day filling of underwater fiberglass pile jackets.
The FX-70 structural piling repair and protection system is a repair solution for damaged concrete, steel, and wood piles, which debuted in 1970. By eliminating the need to build cofferdams or otherwise remove water from project areas, the FX-70 system reduces costs while enabling piers, docks, and other harbor structures to remain in service as pile repairs are executed.
With set times as fast as two hours, the FX-70-6FS epoxy establishes a bottom seal that can support same-day jacket filling, providing marine construction professionals with a repair solution to enhance speed and project efficiency. The water-insensitive epoxy bonds to concrete, timber, and steel pilings and works seamlessly within the FX-70 system to help protect repaired piles from future corrosion, deterioration, or erosion.
According to the U.S. National Oceanic and Atmospheric Administration, the global sea level has been rising over the past century, and the rate has increased in recent decades. In the U.S., almost 40 percent of the population lives in high-population-density coastal areas where sea level plays a role in flooding, shoreline erosion, and hazards from storms. The FX-70 structural repair and protection system provides marine construction professionals with a solution for safeguarding the piling infrastructure that supports roads, bridges, and piers in the harbor and coastal areas at highest risk.
Features and benefits of the FX-70-6FS epoxy bottom seal include:
- Fast-setting epoxy formulation allowing same-day jacket filling
- Pours with ease into FRP jackets
- Water insensitivity to eliminate need for dewatering of project areas
- Freeze-thaw resistant for enhanced protection from temperature fluctuations
- A low-absorption formula for bonding to underwater surfaces
