Bridge bearing pads are a constant maintenance and potential emergency issue for the maintenance crews. Extreme stresses on the columns that transfers directly from the steel to the concrete bearing pads result in early wear and disintegration of the concrete pads. The railroad industry has been searching for a suitable “shock absorber” type system that will mediate the stresses between the steel and the concrete. FastPatch® has proven to be a solution that performs exceptionally well in this tough environment. Due to its fast cure time and installation time, bearing pads are quickly repaired within short breaks of rail traffic.
A flexible and tough concrete repair composite with excellent physical properties. It is a 100% solids, 2-component urethane designed to perform in installations where 5,000 psi concrete is specified.
