Rubber Water Stop Seal Strip

I. Diverse Product Categories

Ordinary Rubber Waterstop Strips

Made from natural rubber or nitrile rubber as the base material, they are processed by extrusion molding, with a strip-shaped cross-section, and can be customized to different widths and thicknesses according to requirements.

They have basic elasticity and sealing properties, can meet static waterproofing needs in general environments, and maintain stable water-stopping performance in dry or slightly damp gaps.

Widely used in non-long-term water-immersed scenarios such as joints between door and window frames and walls, and splicing positions of precast concrete components. They are easy to install and cost-effective.

Water-swellable Rubber Waterstop Strips

Special swelling agents are incorporated into the rubber matrix. In the dry state, they maintain the shape of regular strips, and when in contact with water, they expand rapidly (the expansion ratio is usually 100%-300%) to tightly fill gaps.

The swelling process is gentle and controllable, will not exert excessive pressure on the surrounding structures, and after swelling, they can maintain volume stability for a long time, continuously blocking the water penetration path.

Particularly suitable for parts that may have dynamic water seepage such as underground engineering joints, tunnel circumferential joints, and pipeline interfaces. Even if the gaps have slight changes due to settlement, they can achieve sealing through secondary expansion.

Fabric-reinforced Rubber Waterstop Strips

High-strength fiber fabrics (such as polyester cloth, glass fiber cloth) are embedded inside to improve the tensile and tear resistance of the strips while retaining the elasticity of rubber.

They can withstand a certain degree of transverse tension and longitudinal compression, are not easy to break in scenarios with frequent vibration or displacement, and are suitable for auxiliary sealing of bridge expansion joints, connection joints between mechanical equipment and bases, etc.

The fabric layer is tightly combined with rubber, and its aging resistance is better than that of ordinary strips, with a service life extended by more than 30%.

High-temperature / Low-temperature Resistant Rubber Waterstop Strips

Made of EPDM rubber or silicone rubber, they can maintain elasticity and sealing properties in extreme temperature environments ranging from -50℃ to 150℃, resisting shrinkage or softening caused by sudden temperature changes.

Suitable for special working conditions such as thermal pipeline interfaces, cold storage wall joints, and sealing around industrial kilns, they can withstand the double test of medium temperature fluctuations and environmental temperature differences.

II. Core Performance Advantages

Precise Sealing Adaptability:

Rubber waterstop strips are soft in texture and can be bent and fitted arbitrarily according to the shape of the gap. Even for irregular special-shaped joints, they can achieve dead-angle-free filling, solving the problem that traditional rigid waterproof materials are difficult to cover tiny gaps.

Dynamic Tracking Performance:

Relying on the high elastic modulus of rubber materials, when the structure produces slight displacement due to vibration, settlement, or temperature changes, the strips can synchronously expand, contract, and deform, always maintaining close contact with the joint surface, avoiding the emergence of new leakage channels.

Weather Resistance and Durability:

After anti-ultraviolet and anti-ozone treatment, they can be exposed to the outdoor environment for a long time without cracking or hardening; in media with low acid and alkali concentrations (such as rainwater, groundwater), their service life can reach more than 10 years.

Environmental Protection and Safety Characteristics:

Adopting a solvent-free formula, they do not contain heavy metals and toxic volatile substances, meet the environmental protection standards for building materials, and can be used in drinking water projects, food processing workshops, and other scenarios with strict environmental protection requirements.

III. Wide Application Fields

Construction Engineering:

In parts such as prefabricated building floor splicing joints, curtain wall panel gaps, and elevator shaft side wall joints, they are used as auxiliary waterproof components, cooperating with sealants to improve the overall waterproof grade.

Municipal Facilities:

Used for compartment separation joints of urban underground comprehensive pipe corridors, joints of sedimentation tank walls in sewage treatment plants, and sealing of lap edges of anti-seepage membranes in landfills, resisting the penetration of corrosive liquids.

Water Conservancy and Hydropower:

Suitable for gaps between small sluice gates and gate slots, aqueduct expansion joints, and irrigation channel interfaces, maintaining stable water-stopping effects under long-term immersion and water flow impact.

Transportation Engineering:

In scenarios such as segment joints of metro interval tunnels, gaps between expressway guardrail bases and road surfaces, and sealing of railway culvert entrances and exits, they can adapt to joint changes caused by vehicle vibration and stratum settlement.

IV. Professional Service System

Personalized Customization Service:

Support customization of special specification strips according to the gap size and environmental parameters (temperature, medium type) provided by customers, and provide cross-sectional design suggestions and performance test reports to ensure that the products accurately match engineering needs.

Technical Solution Support:

The technical team can provide overall solutions for strip selection, installation processes (such as pasting, embedding, bolt fixing), and supporting materials (such as special adhesives) according to engineering drawings and on-site working conditions, reducing the risk of construction errors.

Sample Trial Service:

For major projects, free samples can be provided for on-site testing, and product performance can be verified through immersion expansion tests, temperature resistance tests, etc., to help customers make decisions.

After-sales Tracking Guarantee:

After product delivery, installation instruction videos and operation manuals are provided, regular return visits are made to check the usage, and if performance failure is caused by non-human factors, free replacement services can be provided.
