Abstract: PROBLEM TO BE SOLVED: To solve a problem caused by moisture included inside concrete, by applying, to a concrete surface, resin mortar which is comprised of a resin being hardened by reaction even in presence of water, and aggregate, and mixing the resin at a ratio at which the mortar exhibits water permeability, and then sticking a sheet member thereon. SOLUTION: Resin mortar 2 is applied on concrete 1, which is a mixture of a resin such as a polysulfide modified epoxy resin and aggregate such as sand. Then, a wood filler 3 is thinly applied on the surface of the resin mortar layer 2, and a surface coating material 4 is applied on the wood filler 3, followed by hardening the material 4, to thereby obtain a material sheet. To discharge moisture from the resin mortar layer, an opening to be released to the air is formed in some portion of the resin mortar layer. Thus, a moisture passing layer is present below the surface material, and therefore surface material inflation due to moisture retention is prevented. As a result, the life of the surface material is drastically extended and the good appearance of the same is also maintained.
