High Strength Polyurethane Based Injection Resin Neoinject SSR FS is a rapid-curing polyurethane injection resin developed for time-critical repair and stabilization works. Its fast-setting nature makes it perfect for stopping active water leaks sealing cracks and stabilizing soils under urgent conditions. Despite its rapid reaction the resin forms a durable high-strength polymer resistant to hydrostatic pressure and aggressive environments. It is widely used in emergency repair of tunnels retaining walls foundations and underground structures.
