SANDHYAFLEX PVC WATER STOPPER

A PVC water stopper is a device used in construction and civil engineering projects to prevent the passage of water through joints or gaps in concrete structures, such as expansion joints, construction joints, or pipe penetrations. It is typically made from high-quality polyvinyl chloride (PVC) material, which is known for its durability, flexibility, and resistance to water and chemicals.

PVC water stoppers come in various shapes and sizes to suit different applications. They are usually designed as continuous strips or profiles that are installed in the joints or gaps of concrete structures. The most common types of PVC water stoppers include:

1. Straight PVC Water Stopper: This type is a simple, straight strip that is used in construction joints or expansion joints to provide a watertight seal.

2. Bulb Type PVC Water Stopper: It features a bulb-shaped design on one side, which helps to create a better seal against water pressure. The bulb is placed facing towards the water side, and the rest of the strip is embedded in the concrete.

3. Dumbbell Type PVC Water Stopper: This water stopper has a dumbbell-shaped cross-section, with two bulbs on each end and a thinner middle section. It provides enhanced flexibility and is suitable for joints that undergo significant movement.

4. Ribbed PVC Water Stopper: It has ribs or corrugations on the surface, which increase the bonding strength with the concrete and improve the overall sealing performance.

PVC water stoppers are installed during the construction process by embedding them in the concrete at the desired joint locations. The ends of the water stopper are properly spliced or welded to ensure a continuous and secure seal. The flexibility of PVC allows the water stopper to accommodate movements and vibrations in the structure without compromising its effectiveness.

Overall, PVC water stoppers are an important component in waterproofing concrete structures, providing a reliable barrier against the ingress or egress of water and helping to maintain the integrity and durability of the construction.
