Bentonite Waterstop and Tube
 
 

Our factory research and produce all kinds of types and specifications water-swellable band made from bentonite and rubber through using natural sodium bentonite advantage. The products are made of excellent natural sodium bentonite-based materials, and through physical and chemical modification, it has both the function of water swelling, but also has a general elastic body flexibility. In the constraint conditions the product can completely seal the leakage and get the excellent results. Convenient construction, excellent inexpensive price, and the product performance comply with national, industry standards, issued by the State GB50108-2001 <<Underground Projects Waterproof Technical Specifications>>. The quality has reached international advanced level. A number of major projects have been adopted by the State. To ensure its plasticity and improve installation strength, it is suit for the installation of the vertical interface especially.

         

 

一.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.

二.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.

六.Installation and Notes

1. To clear the debris, dross and dust, etc before installing the waterstop and keep the base dry;
2. The waterstop must be fixed with nails or adhesive on the surface of the central position, make sure not fall off;
3. The overlap joints of the waterstop must be parallel connection and form a closed, not leaving the breakpoint;
4. The storage and transport of the waterstop avoid moisture, extrusion, deformation;
5. The package box cantains detailed installation instructions, the construction must follow the instruct
