PROBLEM TO BE SOLVED: To provide a floor-slab waterproof structure constituted so as to be able to easily improve adhesive properties between a waterproof layer and a coating layer, displaying waterproof performance to a floor slab sufficiently and a method for executing the floor-slab waterproof structure. SOLUTION: The floor-slab waterproof structure 11 has the concrete floor slab 12, a primer layer 13, a lower waterproof layer 14 composed of a high- temperature resin, an upper waterproof layer 15 consisting of the high- temperature resin and a heat-resistant nonwoven fabric 18, a lower coating layer 16 composed of the nonwoven fabric 18 and a tack coating agent and an upper coating layer 17 consisting of asphalt. In the floor-slab waterproof structure 11, the nonwoven fabric 18 is laid immediately after the top face of the primer layer 13 is coated with a molten resin, the resin is cured under the state in which the resin is permeated to the lower side of the nonwoven fabric 18, the upper section of the nonwoven fabric 18 is coated sufficiently with the tack coating agent and the tack coating agent is cured under the state in which the upper side of the nonwoven fabric 18 is impregnated, and the upper coating layer 17 is formed by covering with asphalt. |
