Posted outside the water stop, also known as backing with water stop or external water stop, a sealing structure to construct an underground concrete deformation joint, settlement joint outer wall (positive side) settings, having Sealing of elastic material and structure to accommodate the deformation of concrete scalability, from material selection to distinguish can be divided into outer rubber water-stop, externally bonded plastic water stop, posted outside the rubber water stop, etc. The external paste-type water stop or backing with water stop, back paste-type water stop is mainly applied to the floor or wall outside of the concrete structure (concrete positive side). Mainly used in practical applications triggered seam structure, complete contraction joints, incomplete contraction joints and other parts. Having a concrete anchor close, seal and elastic stretch and deformation characteristics, water-stop system using an elastic material, and mixed with various adjuvants, after mixing, curing and made. Depending on the product selection of materials can be divided into natural rubber water stop, chloroprene rubber water stop, nitrile rubber water stop, EPDM rubber water-like. Posted outside the water stop, also known as backing with water stop or external water stop, a sealing structure to construct an underground concrete deformation joint, settlement joint outer wall (positive side) settings, having Sealing of elastic material and structure to accommodate the deformation of concrete scalability, from material selection to distinguish can be divided into outer rubber water-stop, externally bonded plastic water stop, posted outside the rubber water stop, etc. From a structural form it can be divided into EB type water stop and EP-type water stop two kinds. It is worth noting that due to the water stop disposed posted outside welcoming the concrete, in the construction process often requires waterproof plate welded seal, so in this case should be chosen with the same material waterproof board posted outside sealing band (as EVA waterproof board choose EVA posted outside the water stop), while posted outside the water stop after use, in the outer concrete wall backfill should pay attention to the protection of the external paste-type water stop. Our company according to the actual needs of the domestic construction now, in the past, producing a variety of externally bonded rubber water-stop, externally bonded PVC water stop on the basis of the formula, the introduction of advanced equipment and technology, development and production of a series of externally bonded plastic stop, EVA posted outside the main water stop, ECB posted outside the water stop, PE posted outside the water stop, HDPE posted outside the water stop, complete specifications, quality and stability. Customers are welcome to come to negotiate business.
