In view of the low tensile strength of ordinary waterstop, a new waterproof sealing material is developed and produced.

In the vertical construction of some large-scale projects, the ordinary BW water stop is easy to break due to its gravity sag and insufficient tensile strength, which can not achieve the true waterproof purpose. The appearance of a new type of water swelling water stop bar with wire mesh has put an end to this phenomenon. A layer of steel wire mesh or nylon mesh is added to the BW water swelling water stop bar to improve the overall tensile strength of the water stop and ensure the engineering quality.

Product features: This product is a new product with fabric extrusion molding. According to the engineering needs, nylon mesh or steel mesh can be added to the waterstop to increase the tensile strength. The application scope and conditions of the new wire mesh water swelling water stop are basically the same as those of BW water swelling waterstop, and are more suitable for construction sites with large vertical or inclined tension surface.

1. The water blocking principle is that the water stop bar preset in the leakage water gap will expand, block, block and leak water source under the constraint conditions (i.e. under the state of being wrapped by concrete).

2. High expansion ratio and strong mobile supplement. The water stop bar placed in construction joint and post pouring joint has strong balance self-healing function, and can plug new micro cracks caused by settlement by itself.

3. For the completed project, if the joint leaks water, the sealing rod can be used to stop the leakage again.

4. The waterproof and impermeability effect is better than the traditional steel plate, rubber and plastic water stop belt, and the construction method is simple and easy, and saves labor and time.

5. The main material is inorganic mineral raw material, which has the characteristics of aging resistance, corrosion resistance and pollution-free.

Application scope and conditions:

The product is suitable for water stop and impermeability of concrete construction joint, post pouring joint, wall pipe, plate joint and wall joint, and the treatment of concrete crack leakage. It is widely used in highway, subway, basement and so on. BW - Ⅱ series water swelling waterstop is a new type of waterproof and dense material. It is suitable for waterproof and impermeability of concrete construction joint and post pouring joint.
