Text Application scope of back-stick rubber waterstop
Text
Text Externally-stick (back-stick) rubber waterstop, as an auxiliary material for waterproofing boards, can be widely used in basements , waterproofing of subway tunnels, highways and railway tunnels, and waterproofing and anti-seepage of the outside of the concrete structure floor or wall panels (the facing surface of the structure) of dams, artificial lakes, pools, sewage treatment plants, landfills and other projects.

Text The principle of production
Text
Text In practical applications, it is mainly used in deformation joints, expansion joints, settlement joints, etc. with small water pressure and deformation. It has It has the characteristics of tight anchorage to concrete, water-proof sealing and adaptability to the tensile deformation of expansion joints. The back-attached waterstop of the structure can also be used as an ordinary waterstop, which is applied to deformation joints, construction joints and concrete during cast-in-place concrete. In foundation projects where the structure is integrated, back-mounted waterstops are mainly suitable for use on the outside of the base plate or wall panels of concrete structures (concrete facing surface) to solve the problem of water leakage at gaps. It has the characteristics of tight anchorage with concrete, water-proof sealing and elastic tensile deformation. The external waterstop is the first waterproof layer behind the waterproof board and is crucial to preventing tunnel water seepage.

Text
Text method: Equip a thick wooden template on the back of the waterstop. The width and length of the template should meet the requirements for the installation of the waterstop. The formwork should be integrated with the overall formwork of the exterior wall to prevent the wooden formwork from shifting, leaking grout, and losing its water-stopping effect when pouring concrete. At the same time, use double-cap nails to fix the externally attached rubber waterstop to the wooden template. Nail the double-cap nails to the outermost edges of both sides of the waterstop, nailing one double-cap nail every other. The installed waterstop should be flat and without sagging. After pouring concrete, the formwork can be removed only when the strength reaches the design strength.
Text method: Build a thick brick wall on the back of the waterstop as an external formwork. The width and length of the brick wall should meet the requirements for the installation of the waterstop. The brick wall should be consistent with the overall formwork of the exterior wall (steel formwork, bamboo formwork etc.) are connected into one body to avoid grout leakage during pouring and loss of water-stopping effect. Paste a thick EPDM rubber waterproofing membrane or neoprene sheet on the inside of the brick wall in advance (pasted on the plaster layer on the inside of the brick wall and must be firm), and then stick the rubber waterstop firmly with waterproof glue.
