ABSTRACT:
A water-bearing structure, such as a sewer, water line or aqueduct, is sealed to prevent or minimize the leakage of water into or from said structure by placing at the locus of said leakage a fluid sealing composition comprising a water-miscible mixture of isocyanate-terminated polyoxyethylene urethane prepolymers in a compatible, water-miscible solvent, and curing said prepolymer by reaction thereof with water to form a seal at said locus.
