Waterproof structure, waterproof sheet and waterproofing method
The waterproof structure, particularly for use on a roof, comprises a waterproof sheet 10 which is laid on a flat part of a target region 42 and a waterproof coating film 20 formed on at least a part of a peripheral region 44 of the target region on which the waterproof sheet is not laid. The waterproof sheet has a resin sheet 1 containing a poly(vinyl chloride)-based resin and an adhesive layer 3 which is provided on a partial region on one side of the resin sheet and bonded to the foundation. The coating film contains a polyurethane-based resin and is provided so that it is in contact with at least a surface of the rim 11 of the waterproof sheet. Preferably at least the surface of the resin sheet in contact with the coating film is provided with a reactive material that has or generates a functional group capable of reacting with a component of the polyurethane-based resin. Also claimed is a waterproof sheet and a waterproofing method.
