WATERPROOF SHEET, AND WATERPROOF CONSTRUCTION METHOD FOR CONCRETE SURFACE USING IT

摘要

PROBLEM TO BE SOLVED: To provide a waterproof sheet for ensuring adhesion to a construction object, achieving designated bonding strength and dispensing with releasing paper.;SOLUTION: This waterproof sheet 1 has a water-soluble adhesive layer 3 on the back of a base material layer 2 containing modified asphalt or thermoplastic elastomer, and the water-soluble adhesive layer 3 is brought into contact with the surface of concrete before curing, thereby ensuring adhesion of the waterproof sheet 1 to the concrete c. The water-soluble adhesive layer 3 protects the back of the base material layer 2, and contributes to prevention of blocking so that releasing paper is not needed.;COPYRIGHT: (C)2004,JPO
