Rubber Waterstop

◆◆ The advantages of rubber waterstops mainly include:

1. Waterproof Performance: Rubber waterstops can effectively prevent water leakage, flow, and diffusion, ensuring the waterproof effect of buildings.

2. Deformation Adaptability: Rubber has high elasticity, enabling it to adapt to the deformation of structures, provide a good water-stopping effect, and possess resilience, making water stopping safer and more reliable.

3. Chemical Resistance: Rubber waterstops have excellent resistance to chemical media, allowing them to be used for a long time in various environments without being affected.

4. Environmental Friendliness: Water-swellable rubber waterstops do not contain harmful substances, will not pollute the environment, and meet the requirements of green buildings.

5. Ease of Construction: The installation of rubber waterstops is relatively simple, and can be adjusted and fixed according to different construction conditions, reducing construction difficulty and costs.

6. Economy: Although the initial investment is relatively high, rubber waterstops have a long service life and low maintenance costs, and are generally more economical.

7. Seismic Performance: The high elasticity of rubber also endows the waterstop with certain seismic performance, which can reduce the impact of earthquakes on buildings.

1. Classification of Rubber Waterstops：Rubber waterstops can be classified according to different standards. In terms of usage scenarios, they are mainly divided into embedded rubber waterstops and back - pasted rubber waterstops. According to the appearance form, they can be specifically divided into the following categories:

CB type waterstop: It is an embedded waterstop with a hole in the middle.

CP type waterstop: It is an embedded waterstop without a hole in the middle.

EP type waterstop: Also known as external pasted waterstop or back - pasted waterstop, it is an external pasted waterstop without a hole in the middle.

EB type waterstop: That is, an external pasted waterstop with a hole in the middle, which is also called external pasted waterstop or back - pasted waterstop.

2. Specifications of Rubber Waterstops： the commonly used specifications of rubber waterstops include 300×6mm, 300×8mm, 300×10mm, 350×8mm, 400×10mm, etc. Among them, the embedded 651 type is a commonly used model.

3.Application Scope of Rubber Waterstops：Rubber waterstops have a wide range of applications and can be used in waterproofing projects for deformation joints of underground structures, dams, water storage tanks, swimming pools, roofs, as well as buildings and structures.

◆◆ Usage Method of Rubber Waterstop

1. Key Points for Foundation Treatment

Before the start of construction, the foundation must be meticulously treated. The surface of the foundation should be smooth, free of impurities, and meet the specified roughness standards. If there are impurities such as gravel or oil stains on the foundation surface, a steel wire brush must be used for cleaning. Subsequent construction procedures can only proceed after the impurities are completely removed.

2. Length Measurement

When measuring the required length of the rubber waterstop, accurate measurement should be carried out in combination with actual working conditions and design requirements. During operation, in addition to calculating the actual length required for laying the waterstop, an additional redundant length that meets the overlapping specifications must be reserved to ensure installation adaptability and water-stopping efficiency.

3. Length Cutting

Cut the rubber waterstop according to the measured required length. During the cutting process, special cutting tools must be used to ensure that the cutting length is accurate, the cut is neat and free of burrs, and meets the requirements of construction and installation.

4. Waterstop Treatment

After cutting, the rubber waterstop should undergo fusion treatment. It is softened by flame heating, followed by pressure application and kneading operations in sequence. Under the premise of ensuring environmental compliance, the surface of the waterstop should achieve a complete and strong effect.

5. Gluing

For non-cement material parts in buildings, such as wood and brick walls, special glue adhesives must be used for bonding. The thickness of the glue application must be strictly controlled: excessive glue thickness will weaken the bonding stability; insufficient glue thickness will result in poor fixing ability. The glue thickness must be controlled according to standards, as changes in glue dosage directly affect the viscosity and fluidity of the glue, which in turn affects the final bonding effect.

6. Installation

Fit the pre-treated rubber waterstop to the inclined surface; alternatively, use pliers to clamp the waterstop and the board together and fix them on the wall. Simultaneously, reinforce the cut waterstop again to ensure stability and safety after installation. After installation, fasten the ends of the waterstop with buckles to improve the tightness of the waterstop installation.
