Description of rubber water stop Rubber waterstop, made of quality SBR (styrene butadiene rubber),neoprene rubber or natural rubber, is one of the widest types for concrete structure to prevent liquid leaking in or out. Generally,designed to be cast in the concrete, rubber water stops are ideal for applications where high physical properties of rubber are required. For example, reservoirs, dams and other water retaining or excluding applications with high movements or water pressure.

Rubber waterstop, made of quality SBR (styrene butadiene rubber), neoprene rubber or natural rubber, is one of the widest types for concrete structure to prevent liquid leaking in or out. Generally, designed to be cast in the concrete, rubber waterstops are ideal for applications where high physical properties of rubber are required. For example, reservoirs, dams and other water retaining or excluding applications with high movements or water pressure. Features & benefits: High elasticity. High elongation. Excellent high movement accommodation. Capable to withstand high hydrostatic head. Adjust for subsidence and seismic movements. Hot vulcanized site joints. Applications: Ideal for high movements joints. Water containments. Water excluding. Tunnels and civil engineering structures. Water and waste treatments. Dams, reservoirs, and spillway. Chemical areas. Irrigation canals, sea walls and culverts. Main types: Dumbbell type Dumbbell type water stops, with flat web section, are ideal for construction and partial contraction joints with little or no movements. Center bulb type Center bulb type waterstop, as its name implies, features its center bulb which makes it ideal for contraction and expansion joints including high lateral, transverse and shear movements. Meanwhile, it is perfect for withstanding the subsidence of the joints. Installation: All the rubber waterstops are designed to cast in the concrete as an integral joint sealing system. Pre-fabricated waterstops are also supplied to reduce site jointing.
Butyl rubber waterstop is a type of hydrophilic water sealing product to prevent any passage of water through non-moving construction joints. Composed of quality butyl rubber and mastic or expansible clay, when exposed to water, the waterstop swells and forms a permanent compression seal in non-moving concrete construction joints. Features: Preserve its integrity with self-control ability. Easy and fast to install owing to its high self-adhesive properties to dry surface. Form a permanently flexible watertight joints. Anti-aging without shrinkage, hardening and oxidization. Withstand harsh temperatures ranging from -30°F to 200°F. Non-toxic. No need of special handling. Application: Concrete construction joints. Non-moving joints. Portable water tank, box culverts and tunnels. Water containments. Pipe penetrations. Manholes. Slab and walls below grade. Cast in place applications. Foundations and basements. Utility and burial vaults. Precast concrete wall panel system. Wet wells. Note: Before installation, do not forget to clean and dry the surface of the concrete. Butyl waterstops should be stored in cool, dark and dry environment, away from moistures. Not appropriate for expansion and moving joints. Please make sure a minimum 2 inches of concrete coverage is left before installation to reduce spalling and cracking of surrounding concrete caused by expansion pressure of the waterstop. When it comes to lightweight, low strength and insufficient concrete with low compressive strength less than 3500 psi, please increase the coverage. Before the second pour of concrete, check the waterstop for premature swell, discontinuity and debris contamination. If so, immediately replace it with a new one. Concrete nails are acceptable to fix the butyl waterstop if necessary.
Waterstop is " A section of flexible waterproofing material placed at any joint in concrete to prevent passage of water ". Joints in concrete structures, one side is subject to hydrostatic load, are provided with waterstops bridging the joints and embedded in concrete on either side. In concrete joints where expansion and contraction cause the joints to close and open, waterstop then are designed to accommodate itself to such movements. Flexijoint Natural Rubber Waterstops are superior in performance than metal or pvc withstanding shear movements resisting hydrostatic pressure. Flexijoint Natural Rubber Waterstop have greater ultimate elongation of minimum 400% greater than PVC and will continue returning to near original shape after repeated movement. They have lower compression set and perform well at low temperatures. Flexijoint Natural Rubber ( NR ) series Waterstop is moulded from high grade valcanised natural rubber compound and free from reclaimed rubber or vulcanized waste.Flexijoint NR Waterstop widely applied in construction industry. Flexijoint Natural Rubber ( NR ) Waterstop " Dumbell Plain Web " Series.Size 150mm and 230mm width suitable for construction, kicker and partial contraction joints where no shear movement is possible. Flexijoint NR Waterstop Application: Dams, Canals, Culverts, Spillways, Tunnels, Water Towers, Swimming Pools, Reservoirs, Sewerage Tanks, Basements Substructures & Underground Car Parks, Subways, Roof Decks and Podium Areas.

Ω type inserted rubber waterstop, also called © type inserted rubber sealing, is a kind of flexible rubber waterstop. Its middle is semi-circular structure and both sides are flats structure. The middle of the semicircle structure is to have better stretch and compression in the deformation process of expansion joints. It is not poured into concrete. It is installed on the concrete surface through slotted after the concrete construction is completed. © type inserted rubber waterstop can be used as a kind of waterproof measure as a late remedy. If the expansion joints leaking, we can add a layer of © type inserted rubber waterstop later. If the © type inserted rubber waterstop is also destroyed, you can remove the original and then re-install a layer. In addition, our waterstop product with high elasticity and corrosion resistance is not easy to be damaged. It has a long service life. Specification Material: natural rubber, neoprene rubber, EPDM etc. Width: 200 400 mm. Other specifications also can be customized. Length: We can customize any length according to your request. Temperature range: -45 °C to +60°C. Feature High elasticity and compressive deformability. Corrosion resistance, wear resistance. Removable, easy to install and replace. Aging and tear resistance, long service life. Good adapt to deformation ability. Excellent waterproof performance. Installation tips Embedded bolt construction. Embedded bolts must be fixed on the steel plate in advance, and then pour the concrete. The concrete that under the embedded steel plate should be shocked and mashed. The corners of the deformation seam should be made circular arc or 45° angle. Arc radius should be based on the length of embedded bolts to determine. The distance between two adjacent bolt heads can not affect the installation of the waterstop. Embedded steel plate and plywood also should be made into the same shape. When embedding the bolt, we should use PVC tube to protect bolt after coated with butter. The fix of Ω type inserted rubber waterstop.We should use belt punching to fix the waterstop according to the actual position of the bolt. During the entire installation process, must not be hard to pull the waterstop. The space between waterstop and embedded steel plate should use asbestos cardboard or soft metal sheet to make it tighter. Application Underground construction. Dam. Storage tank. Water reservoirs. Swimming pool. Bridge. Tunnel. Water and waste water treatment facilities.
