EXTERNAL HEAT-INSULATION COMPOSITE WATERPROOF CONSTRUCTION METHOD AND STRUCTURE OBTAINED THEREBY

PROBLEM TO BE SOLVED: To provide an external heat-insulation composite waterproof construction method and a structure obtained thereby, securing a ventilation path by means of a simple composition, having excellent adaptability properties to the substrate and high strength, and shorten the term of work. SOLUTION: A thermal insulating material F is laid directly or through an appropriate layer on the surface of a substrate 1, a sheet type roofing material 2 is laid on the material F, and the material F and the roofing material 2 are mechanically fixed together by metal fitting 3. After that, an FRP layer 6 is formed on the roofing material 2 directly or through the layer of an adhesive butyl tape 4, etc., with a non-woven fabric.
