す欠点があった。(Prior Art) In refrigerated warehouses and the like, it is necessary to carry out moisture-proof work in order to prevent ingress of moisture from the outside. Conventionally, in this construction, asphalt roofing is laid on the base using hot asphalt, or as another method, a sheet in which an asphalt adhesive layer is laminated on a base material made of aluminum foil with high moisture permeability resistance does not use hot asphalt. It was laid directly on the ground. (Problems to be solved by the invention) However, in this moisture-proof sheet, the aluminum foil is very thin, 5 to 50 μm, and once it is cracked, tearing easily occurs, and the aluminum foil itself is easily scratched, Further, it has a drawback that it easily causes chemical deterioration to acids and alkaline substances.

Furthermore, the presence of the reinforcing material makes it difficult for the aluminum foil itself to be deformed, so that tearing does not easily occur. Moreover, since the split cloth is used as a reinforcing material, physical properties in the longitudinal and transverse directions (tensile strength, elongation, etc.)
Have almost the same characteristics and become a non-directional moisture-proof sheet to facilitate the laying work, and the adhesive layer penetrates into the opening to firmly bond with the upper layer of the reinforcing material.
