ABSTRACT:
A compound water-sealing sealant comprising a non-water-swelling thermoplastic resin (A), preferably a vinyl chloride resin, and a water-swelling resin (C) obtained by kneading together 10 to 97% by weight of the non-water-swelling thermoplastic resin (A) and 3 to 90% by weight of a water-swelling material (B). The compound water-sealing sealant is molded by the conjoint extrusion molding of the non-water-swelling thermoplastic resin (A) and the water-swelling resin (C). The water-swelling material (B) is a water-swelling urethane resin which is a prepolymer having isocyanate groups in which the content of terminal NCO groups amounts to 1 to 12%, preferably 2 to 7%, obtained by the reaction of polyisocyanate with at least one polyether polyol of the formula
