PLEASANTON, Calif. – Simpson Strong-Tie, a structural systems research, testing and innovation company, has a new video highlighting the first full-scale, cyclic tests of repaired wood piles using the FX-70 Structural Repair and Protection System. The tests verify the system’s performance capabilities and will provide engineers with real-world data to help them evaluate the FX-70 system as a potential solution for their structural repair applications.

The three-minute video, available at, shows how the test was conducted at the Simpson Strong-Tie Tyrell Gilb Research Laboratory in Stockton, Calif. Developed by the Simpson Strong-Tie Engineering Department, the testing demonstrated that the FX-70 jacket system performs as intended and is an effective structural repair solution.

Simpson Strong-Tie entered the repair, protection and strengthening industry after acquiring Fox Industries in late 2011. The FX-70 Structural 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, FX-70 drastically reduces the overall expense and loss-of-use cost as the structure can generally remain in-service while the repair is executed. Manufactured in the U.S., the system is customized to the requirements of each project and site.

The Simpson Strong-Tie line of repair, protection and strengthening systems for concrete and masonry includes a wide variety of new products, including repair mortars, coatings, grouts, epoxies, sealants and the FX-70 structural repair and protection system. The new Repair, Protection and Strengthening Systems for Concrete and Masonry product guide features all of the new products and is available at
