Simpson Strong-Tie Composite Strengthening Systems (CSS) provide efficient solutions for the structural reinforcement and retrofit of aging, damaged or overloaded concrete, masonry, steel and timber structures.

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

The concrete repair, protection and strengthening solutions developed by Simpson Strong-Tie are the result of over 40 years of laboratory development, field study and collaboration with professional contractors. Each of these products have passed the performance and quality assurance protocols that are expected of Simpson Strong-Tie, and have been selected to address the unique challenges of Commercial Retrofit, Bridge and Marine and Water/Wastewater projects.
