| ■ Product description |
Waterstop strips is a hydrophilic swelling bentonite waterstop. The based material is bentonite clay with polymer rubber. The product swell when contact with water create more than 300% expansion. The release benonite fill void between the two portion of concrete joint.
| ■ Area of uses |
◇ Construction joints. ◇ Water tank, waste water tank. ◇ Tunnels. ◇ Basements. ◇ Elevator pits. ◇ Retaining walls. ◇ Pipe penetration. ◇ King post. ◇ Sheet pile joint. ◇ Precast concrete structure. ◇ Block out. ◇ Pile cap.
| ■ Advantages |
◇ Withstand hydrostatic pressure. ◇ Can use in portable water tanks. ◇ Fast and easy installation. ◇ Fast track project. ◇ Easy to joining. ◇ Durability. ◇ Economical. ◇ Easy to transport.
| ■ Applications |
1. Vertical and horizontal concrete construction joints;
2. Junction of old and new buildings;
3. Around wall pipe (including pipe and cable ducts);
4. Can be constructed in irregular surface;
5. Sealing the gap of all kinds of buildings, tunnels, underground projects and water engineering.
| ■ Main Advantages |
1. Construction simple, rapid, individual could be independent construct;
2. Easy to install and cut, no weld seams and other installation accessories;
3. Active sealing performance and permanent stability;
4. Comprehensive cost-effective;
5. Can be construct in both cold and hot weather, and can be used in the irregular surface;
6. Domestic and international practice proved to be the best construction joint waterproofing products.
