Backing with rubber water stop, also known as external paste-type water stop or external water stop, a sealing structure to construct an underground concrete deformation joint, settlement joint outer wall (positive side) is provided, with Sealing elastic material and structure to adapt to deformation of concrete stretching from material selection to distinguish can be divided into outer rubber water-stop, externally bonded plastic water stop, rubber water stop posted outside and the buried water swelling water stop, etc. From a structural form 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. Backing with rubber water-water stop is made from PVC, EVA resin filled with a variety of additives, sealing materials have been made in the production process. EVA water stop use of an elastomeric material having elastic deformation characteristics play in leakproof joints in building construction, seepage effect, EVA waterstops are resistant to corrosion, durability and good. Applications: EVA backing with water stop as a water board DPM can be widely used in the basement, underground tunnels, water works road and rail tunnels, dams, artificial lakes, ponds, sewage treatment plants, landfills and other projects waterproof and impermeable. Also EVA backing with water stop is also available as a separate water stop use, when applied to concrete cast Deformation, construction joints and concrete structure has become one of the foundation work, water leakage problem of the gap at the decision. Our company can produce different technological phenomenon mouth, different sizes. Different sections of the backing with water stop, water stop different materials have different standards. 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 and so on.
