A **center-embedded water stop** is a type of water barrier or sealant used in construction to prevent water infiltration in joints, particularly in concrete structures like foundations, tunnels, reservoirs, and water treatment facilities. It is installed in the middle (center) of a concrete pour or between construction joints to block the passage of water through gaps or cracks.
1. Excellent Waterproof Sealing Performance
Made of highly elastic materials (such as PVC, rubber, or hydrophilic expansion materials), tightly embedded in concrete joints to effectively prevent water penetration.
Suitable for long-term water pressure environments (e.g., reservoirs, tunnels, basements), preventing leaks and structural damage.
2. High Durability and Anti-Aging Properties
Resistant to corrosion, acids, alkalis, and UV rays (suitable for exposed environments).
Long service life, synchronized with the concrete structure, reducing maintenance costs.
3. Strong Adaptability
Compatible with joints of varying widths (e.g., expansion joints, construction joints, settlement joints).
Some products (e.g., hydrophilic water stops) expand upon contact with water, automatically filling gaps to enhance sealing.
4. Easy Installation and Reliable Construction
Pre-embedded design, fixed during concrete pouring to integrate with the structure and prevent displacement.
Multiple connection methods available (heat welding, adhesive bonding, overlapping) to ensure no weak points at joints.
5. Environmentally Friendly and Safe
Complies with eco-friendly standards for waterproof construction materials; non-toxic and safe for potable water projects (e.g., water tanks, sewage treatment plants).
6. Cost-Effective
One-time pre-installation reduces post-construction leakage repair costs.
Enhances overall waterproofing performance and extends the structure’s lifespan.
Application Scenario | Recommended Type | Key Advantage |
---|---|---|
Basements/Underground Works | PVC or Rubber Water Stop | High elasticity, resistant to soil pressure and groundwater erosion |
Tunnels/Subways | Hydrophilic Expansion Water Stop | Self-expands upon water contact, filling fine cracks |
Dams/Reservoirs | Metal Water Stop (Copper/Stainless Steel) | High-pressure resistance, impact-resistant, long lifespan |
Sewage Treatment Plants | Chemical-Resistant Rubber Water Stop | Resists chemical corrosion, prevents leakage |
