PROBLEM TO BE SOLVED: To provide a weather resistance protecting method for securing the long-term durability of a protected waterproof layer of a concrete structure such as a bridge, even when exposed directly to sunlight, with easy construction, and to provide the structure withstanding against long-term use, on which people can walk. SOLUTION: The weather resistance protecting method for the waterproof layer comprises pasting a multilayer sheet consisting of, at least, a weather resistant film layer (A) and a heat resistant and highly strong film layer (B), to the outer surface of the waterproof layer (D) formed on the surface of a concrete via an adhesive layer (C) or with a specified adhesive. It is desirable that the (A) layer is a vinylidene fluoride resin film and the (B) layer is an extensible film of polycarbonate or, etc. COPYRIGHT: (C)2003,JPO |
