Detailed introduction
The swellable waterstop is a new rubber product that based on the raw rubber materials, with a polymer material,throughing chemical modification. It has the characteristics of rubber and swellable to proof water.
It be divided into bentonite waterstop and production waterstop.
The swellable waterstop have the excellent flexibility, expansion ability, plasticity when water intrude, it is widely used in tnnels, subway, sewage plant, the municipal pipe network,Culvert, dam, bridge construction, water conservance, hydropower projects, building underground,Structure construction joints, expansion joints and waterproofing of concrete work required.
The main technical performance indicators:
| Item | Indicators | |||

| 2 | High-temperature flow of (80℃x5H) | No flowing | No flowing | No flowing |
| 3 | Low-temperature test(-20℃x5H) | No embrittlement | No embrittlement | No embrittlement |
Product specifications:
10×10mm、10×30mm、15×20mm、20×10mm、20×25mm、20×30mm、20×50mm、30×50mm、50×50mm etc.
Also we can produce the slow-expanding type, to strengthen the network type, such as various type of water swelling waterstop article.
Introduction:
◆ The based material is bentonite clay with polymer rubber.
◆ The product swell when contact with water create more than 300% expansion.
◆ The release bentonite fill void between the two portions of concrete joint.
Size and Packaging:
◆ 25mm x 20mm x 5meter (30 Meter/box)
◆ 20mm x 15mm x 6meter (36 Meter/box)
