  • Method and composition for repairing cementitious surfaces
    Patent number: 4659748
    Abstract: An improved method and composition for repairing cementitious surfaces is provided. A polymerizable urethane composition having an excess of isocyanate groups to account for water present in the reaction environment is utilized. The method utilizes water, e.g. surface moisture, to foam the polymer and provide a long-lived repair of the surface. The method is particularly applicable in the repair of concrete roadways.
