Product Description

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 is widly used in construction concrete joints.

Steel Side Rubber Water Stop/Waterproofing Waterstop From China Supplier
Steel side waterstops is scalable rubber and galvanized steel composite. Steel depends mainly on the edge of the water stop rubber section in the middle between the concrete deformation joint compression or stretch, and play the role of the seal sealing. Generally speaking, the poor adhesion of concrete and rubber, because rubber is a soft elastomer in conventional construction, the concrete pouring difficult to dig real, so the expansion of concrete joints, pulled away from the will to reverse the often rubber water-stop loose and fell off, resulting in high head pressure leakage. For deformation joint large joints, always more prominent. Galvanized steel modular rubber water stop, and basically be able to overcome these deficiencies of the pure rubber bridge water stop. And this combined water stop also has a dual function: on the one hand may be extended way, slow seepage speed, on the other hand, galvanized steel and concrete have a good adhesion, water stop can withstand greater tension and torsion, thus ensuring the effective deformation range of rubber water-stop concrete does not produce loose and fell off the phenomenon to improve the sealing effect.

Waterstop types:

According to different raw materials, waterstops can be classified into:

--rubber waterstop (natural rubber waterstop, neoprene / chloroprene waterstop, synthetic rubber waterstop, bentonite / expanding waterstop, EPDM waterstop)

--pvc waterstop

--steel waterstop

--rubber waterstop with steel edge

length:usually 20m or 25m per roll.
width: 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm etc.
thickness: 3mm-20mm.
costomized demensions are available

Features of Rubber Water Stop:

--high tensile strength and good elasticity

--corrosion and weather resistant

--can withstand high hydrostatic pressure

--can bear shocks of heavy turbines, earthquacks and floods etc.

--easy and quick operation

--waterproofing, good sealability

--low cost, comparing with steel waterstop

Application of Rubber Water Stop:
Widely used in concrete joint and deform crack, joint reinforce or preventive waterproofing project, such as underground construction, tunnel, dam, culvert, pond, metro etc.

Choices of Rubber Water Stop:

  1. According to the grade of the importance of buildings, deformation and water pressure, the working condition of the waterstops' application and economic factors.
  2. According to the following provision:
    • Choose natural rubber waterstop in normal situation
    • Choose neoprene waterstop when it comes to weak acid and alkaline corrosive medium
    • Choose butyronitrile rubber waterstop when it comes to oils medium
    • When waterstop might be eroded by mould, take its mildew resistance into consideration, and its level should reach Grade 2 and above.
    • Choose neoprene waterstop when the operating temperature is between -25ºC~60ºC, choose natural rubber waterstop when the operating temperature is between -35ºC~60ºC while at -40ºC~60ºC EPDM rubber waterstop should be chosen.
    • Choose synthetic resin waterstop (EVA,PE,ECB,HDPE,PVC) with the same molecular when welded with waterproof board or other matetrials.

    3. Other factors

             a. Deformation volume of the deformation joint in horizontal and vertical direction

             b. Water pressure

             c. Size of structure section


  • Physical and mechanical properties : The rubber waterstop produced in our company is complied with National Standard GB18173.2-2000. The technical requirements of size and tolerance is implemented by National Standard. But if there are special requirements ,we can produce according to customers' requirements.
  • Product should avoid sunlight during transportation and storage. Do not contact with heat source, oil, harmful solvent and the materials that can affect the quality of rubber. It should be laid vertically. Storage places are better to keep the temperature between -10ºC~+30ºC and the relative humidity between 40%--80%, which should be kept clean.

20m-25m in a roll ,in plastic bags or with plastic film, in bulk or wooden pallets.
