ABSTRACT:
An encapsulating and patching elastomer for concrete repairs including a two component urethane system including a polyol reacted with a diisocyanate or a mixture of diisocyanates and a hindered amine, and an aggregate filler. The elastomer polyester filler has a hardness of over 50 on the Shore A scale. The subject invention further provides a method of making an encapsulating and patching elastomer for concrete repairs, the method including the steps of dissolving the two component urethane system with the hindered amine. The mixture is applied as a film or patch to a concrete surface. The mixture is cured at ambient temperature for 48 to 72 hours to an elastomer having a hardness of over 50 on the Shore A scale.
