what is waterstop?
General Characteristics
- Material Characteristics
The waterstop has good elasticity and sealing, and can adapt to the deformation and displacement of the concrete structure.
- Structural Form
The waterstop is generally a strip structure, which can be cut into different lengths and shapes according to the needs. Its surface is often convex or grooved to increase the friction with the concrete.
- Installation Position
Waterstop is installed in the center of concrete joints or expansion joints to fill the gaps through extrusion and deformation to achieve waterproof effect.The waterstop is generally a strip structure, which can be cut into different lengths and shapes according to the needs. Its surface is often convex or grooved to increase the friction with the concrete.
- Material Price
The price of waterstop is also affected by the material, specifications and manufacturers and other factors, the price of rubber waterstop is relatively low, the common market price of rubber waterstop in a few dollars per meter to a few dozen dollars, some special materials or high-performance waterstop price is higher.
Specification Selection
Rubber water stops have various specifications and models, common types include buried type, external paste type, steel edge type and so on. Width can range from 200mm to 400mm, thickness can range from 0.6cm to 1.0cm. Specific specifications such as type 651, 652, 654, etc., each type has its specific size and application scenarios.
- Type Selection
According to the project parts and construction conditions to choose the appropriate type of waterstop, such as buried waterstop for concrete internal joints, external waterstop for concrete external joints.
- Size Selection
According to the width and depth of the joints to choose the appropriate size of the waterstop, the width should be able to completely cover the joints, the thickness should meet the waterproof requirements.
- Material Selection
Select the rubber waterstop material which is qualified by the national measurement certification inspection department to ensure the water stopping effect and service life.

Scope of Application
Waterstop has good elasticity, abrasion resistance, aging resistance and tear resistance, strong ability to adapt to deformation, and good waterproof performance. Its price, performance, construction difficulty between the water stop and water stop steel plate, wide range of application, especially for large deformation of the settlement deformation requirements of the parts, the selection of comprehensive consideration.
- Importance level of structures
For structures with high importance level, the use of waterstop should be prioritized to ensure the waterproof effect.
- Deformation amount and water pressure of deformation joints
In the case of large deformation of deformation joints or large water pressure, the waterstop can play a better waterproof effect.
- Construction conditions
When constructing the waterstop, it is necessary to pay attention to the positioning method and pouring pressure so as not to be punctured or torn to affect the waterstopping effect, and at the same time, it should be ensured that the waterstop is correctly positioned and reliably fixed in the concrete.
