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

RSP is a two-part polyurethane product that provides a quick, cost-effective solution for repairing potholes, pavement cracks, and more. For minor repairs, RSP is easy-to-use and 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 may be used along with RSP. Simply fill a void in the pavement to the top with aggregate, then pour RSP on top until it fills in around the aggregate and is level with the road surface.
