Roadware 10 minute conrcete mender™ is a two-part polyurethane that penetrates deep into concrete to make permanent repairs. Nearly thin as water at less than 9cps, concrete mender™ actually injects itself into the matrix of the concrete and shores up the existing concrete as well as making the repair. Concrete mender™ eliminates the bond-line as it microdowels into the concrete. We call it microdowling™.
