RR401 | 4lb Concrete Raising Foam

Heavy-duty polyurethane foam perfect for D.O.T. & industrial concrete repair

RR401-application-photo Rocking concrete slabs caused by high traffic and heavy loads can lead to traffic hazards on our roads and possible OSHA issues in commercial or industrial settings.

These safety issues require resolution, and ultimately led us to create a foam specifically for D.O.T., municipal, industrial, and commercial applications.
