The strong, fast, effective polyurethane backfill alternative to asphalt and concrete patching.

Still using traditional pavement repair methods like asphalt and concrete that don’t last? RSP™ is a two-part polyurethane product that provides a simple, quick, cost-effective solution for repairing potholes, pavement cracks, spall, as well as loose or failed concrete roadway sections.

For minor repairs, RSP™ is easy-to-use, and doesn’t require any special skills, training or tools. And it sets in just minutes, transforming from a low viscosity liquid into a solid material with a compressive strength of over 7,000 psi.

For major repairs, clean, dry aggregate materials may be used along with RSP™. Simply fill the void to the top with aggregate, and then pour on the RSP until it fills in around the aggregate and is level with the road surface.
