A PVC water stopper is a type of material commonly used in construction, particularly in concrete joints, to prevent the passage of water. It’s typically made of flexible PVC (polyvinyl chloride) and is designed to be placed in expansion joints, construction joints, or around the edges of concrete structures to form a seal that prevents water infiltration.
Here are a few key points about PVC water stoppers:
Waterproofing: The primary function is to block water from seeping through joints and cracks in concrete structures, like basements, tunnels, reservoirs, and water treatment plants.
Flexible: PVC water stoppers are highly flexible, allowing them to expand and contract with the concrete, maintaining a tight seal throughout the life of the structure.
Durability: They are resistant to chemicals, weather, and physical wear, which makes them suitable for both indoor and outdoor applications in various environmental conditions.
Installation: PVC water stoppers are typically embedded into the concrete during the pouring process. The material is placed into the formwork, and once the concrete hardens, the water stopper creates a barrier at the joint.
Types: There are different profiles of PVC water stoppers, like the flat, ribbed, and U-shaped designs, depending on the specific requirements of the project.
