A PVC water stopper is a specialized product used in construction to prevent the passage of water through joints or cracks in structures like concrete walls, floors, or foundations. Made from durable polyvinyl chloride (PVC), it is commonly used in projects such as basements, tunnels, reservoirs, and dams to create a watertight seal.
Key Characteristics:
- Waterproofing: It is primarily designed to stop water from seeping through concrete joints.
- Durability: PVC is resistant to chemicals, corrosion, and physical wear, ensuring long-lasting protection.
- Flexibility: Many PVC water stoppers are designed to be flexible enough to handle joint movement caused by settling or thermal expansion of concrete.
- Easy Installation: They are typically installed during the construction phase by embedding them into the concrete formwork at the joint locations.
Types of PVC Water Stoppers:
- Flat Type: A simple flat design, placed along the joint for basic water resistance.
- Profile Type: Features a more complex, ribbed or molded design for better sealing and enhanced durability.
- Flange Type: Comes with flanges for better bonding to the concrete and more effective sealing.
Applications:
- Water Treatment Plants
- Dams
- Underground Parking
- Tunnels
- Swimming Pools
- Reservoirs
PVC water stoppers are essential in any construction project where water leakage could be a problem, helping ensure that structures remain dry and intact over time.
