PROBLEM TO BE SOLVED: To provide a waterproof laminate for the corners or drainageway parts of a bridge floor panel capable of preventing the corrosion or crack of a reinforcing rod, generating no leakage of water with high adhesiveness or strength, being executed at the normal temperature, being applied to concrete even if the surface of concrete is in a wet state, and being enhanced in weatherability or execution properties. SOLUTION: The waterproof laminate is constituted by laminating a spraying waterproof material, a sheetlike waterproof material and, if necessary, a weatherable coating material. As the spraying waterproof material, a normal temperature vulcanizable rubber emulsion is preferable and, as the sheetlike waterproof material, a rubber asphalt type sheet is preferable. After the spraying waterproof material 1 and the sheetlike waterproof materials 2 and 2' are applied to the corners 3, floor panel 4 and drainageway parts of a bridge, if necessary, the weatherable coating material is executed to perform waterproof construction.
