A 300mm PVC Water Stopper is a crucial construction material used for sealing construction joints and expansion joints in concrete structures to prevent water leakage or seepage. Here's a breakdown for you:
Its a flexible PVC (Polyvinyl Chloride) strip, embedded in concrete joints to form a watertight seal. A 300mm wide variant is typically used in large structures like:
Water tanks
Dams
Basements
Retaining walls
Tunnels
Swimming pools

Application : Sandhya Enterprises are one of the top manufacturers in India. Water Stoppers are the flexible plastic strips that are used to provide a physical barrier to water. The barriers can be at concrete joints in basements, waterretaining structures like water tanks, swimming pools, structural foundations and other constructions of below ground level. Water stoppers are also known as water bars and seal construction joints. In a typical water stopper, there are two identical halves on both sides of the central bulb. They serve as an additional extension aiming to increase the path length for water entering behind the edge of water stopper. Compounding of PVC Water Stopper Antiageing customized plastic compound is used for manufacturing the water stoppers. Alongside, it has PVC as a base polymer. Moreover, the properties it exhibit are high elasticity and tensile strength, immunity to corrosion, excellent weather resistance, unaffected by acids, alkalis, metals, salts and other chemicals. Other properties include lower water absorption, high hydrostatic pressure withstanding capacity, heavy turbine shock bearing alongside earthquakes and floods. Application in construction industry The PVC water stopper acts as a sealant at RCC Masonry concrete joints alongside preventing any water seepage through the joints.
