PVC Water stopper

About PVC Water stopper

PVC water stoppers are flexible, durable sealing elements used in concrete structures to prevent water leakage and ingress at construction joints, expansion joints, and movement joints. They are commonly made from polyvinyl chloride (PVC), which provides excellent resistance to water, chemicals, and aging.

Types of PVC Water Stoppers:

1. Center Bulb: Designed for expansion joints where movement is expected. The center bulb allows flexibility.
2. Dumbbell Shape: Used in construction joints to provide basic sealing.
3. Ribbed with Center Bulb: Combines ribbed structure for better anchoring with flexibility provided by the center bulb.
4. Kicker Type: Designed for specific applications like retaining walls and slabs.
5. External and Internal Profiles:
   • External: Installed outside the joint, mainly for water containment structures.
   • Internal: Embedded in the concrete to seal the joint effectively.

Features:

• High tensile strength and elongation properties.
• Resistant to chemicals and weathering.
• Flexibility to accommodate joint movement.
• Easy to weld or join during installation.

Applications:

• Water tanks and reservoirs.
• Dams and canals.
• Underground structures like basements and tunnels.
• Bridges and flyovers.
• Retaining walls and swimming pools.

Installation Tips:

• Ensure proper alignment during installation to maintain an effective seal.
• Use appropriate welding techniques for joining PVC water stoppers.
• Protect from damage during concreting and handle with care to avoid deformation.
