Abstract: A waterproof sheet which is for application to a site to be waterproofed in order to prevent rainwater infiltration thereinto and retard deteriorations which proceed with time, the waterproof sheet comprising: a base layer that comprises a silicone rubber composition reinforced with reinforcing fibers and that has physical properties including high strength; and a pressure-sensitive silicone adhesive layer that has been formed on one surface of the base layer and that has a low hardness and is highly tacky. The waterproof sheet provided by the present invention less breaks than conventional waterproof sheets because of the reinforcement layer, and can conform to cracks or dislocations occurring in the surfaces to which the waterproof sheet has been applied, due to the pressure-sensitive adhesive layer formed on one surface.

Abstract: A waterproof sheet which comprises a base layer constituted of a silicone rubber and a pressure-sensitive adhesive layer superposed thereon and which is for use in preventing the infiltration of rainwater, etc., characterized in that the pressure-sensitive adhesive layer is constituted of a cured object of an addition reaction type curable silicone composition in which the theoretical amount of crosslinks is 0.005-0.01 mol/g and the ratio of the amount of SiH groups to the amount of alkenyl groups, SiH/alkenyl, is 0.5-1.1 by mole and which, when cured, has a hardness as measured with a CSR-2 type hardness meter of 3-20. This waterproof sheet can be used over a long period without decreasing in physical property, and has waterproofing properties over a long period. In particular, by delimiting the hardness and adhesive force of the pressure-sensitive adhesive layer, the waterproof sheet can be made to withstand long-term use.

Abstract: Provided is a waterproof sheet such that an adhesive layer is formed on a substrate rubber layer and characterized by the substrate rubber layer comprising a silicone rubber having a JIS-A hardness of 15-90, a tensile strength of at least 3 MPa, an elongation of 100-800%, and a crescent tear strength of at least 3 kN/m. The waterproof sheet can be used without a long-term decrease in material properties, and is waterproof in the long-term. In particular, the present invention can be a waterproof sheet able to withstand long-term use by means of stipulating the material properties of the substrate rubber. By means of a method for applying waterproofing to an outdoor tank, it is possible to reliably waterproof the bottom side of the outdoor tank by means of a simple application method.

Abstract: When a bridge pier is reinforced or repaired by wrapping a reinforcement around the pier, a waterproof sheet having a sufficient flexibility to attach to and cover the interface between the pier and the reinforcement in a liquid-tight manner is useful. The waterproof sheet is attached to the interface between the pier and the reinforcement to prevent water from penetrating into the interface for thereby preventing the reinforcement from deterioration.
