A waterproof structure is provided to prevent breakage, exfoliation and crack of structure when it is expanded and meved. A waterproof structure as follows. A polyester non-woven fabric(12) is welded by the heat sealing in the synthetic resin system upper surface of seat of the thickness 0.8 ~ 1.2mm. A penetration hole(11) is manifoldly formed in the end part of the sheet according to circumference into the constant interval. In the upper side of the bottom concrete(1), in order to two sheets be brought into contact of 5~10mm, it has crevice it is fixed to the lower part point wearing film ash(20) and upper part point wearing film ash(21). The waterproof structure comprises a synthetic resin sheet(10) in which the upper part point wearing film ash is integrated in each other and which is fixed it is brought into contact, a thermoplastic urethane film(40) adhered on the upper part point wearing film ash, a semirigid urethane film layer(30) in which the urethane type film ash is coated onto the thermoplastic urethane top of film with uniformly and which is formed, silica layer(50) which uniformly spreads the silica 5~6 th in the coating of the urethane type film ash and is formed, a top coating layer(60) in which the topcoat material is coated onto the silica layer upper side and which is formed for the yellowing cut off. |
