PVC Water Stopper

About PVC Water Stopper

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, water-retaining 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

Anti-ageing 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.
• A PVC water stopper is a type of construction material used to prevent the passage of water through joints or gaps in structures such as concrete walls, floors, or basements. It is commonly used in applications where water leakage needs to be controlled or prevented, such as in swimming pools, water tanks, tunnels, or underground structures.
  
  
  PVC water stoppers are made from polyvinyl chloride (PVC), a durable and flexible plastic material. They are designed in various shapes and sizes to accommodate different joint configurations and construction requirements. The most common types of PVC water stoppers include:
  
  
  1. Straight Water Stopper: This type of water stopper is used in straight joints or construction joints where two concrete sections meet. It provides a barrier against water infiltration.
  
  
  2. Internal and External Corners: These water stoppers are specifically designed to fit into the internal and external corners of joints, ensuring a watertight seal at these critical areas.
  
  
  3. Bulb-Type Water Stopper: This water stopper features a bulbous shape that provides additional flexibility and sealing capacity. It is suitable for applications where joints are subject to movement or expansion.
  
  
  4. Ribbed Water Stopper: Ribbed water stoppers have a ribbed surface that enhances the grip and bonding with concrete. This type of water stopper offers excellent sealing capabilities and is commonly used in high-pressure water applications.
  
  
  PVC water stoppers are typically installed during the concrete pouring process. They are embedded within the joints, ensuring a secure and watertight seal. The flexibility of PVC allows the water stopper to accommodate movement or settling of the surrounding structures without compromising its sealing properties.
  
  
  It is important to follow the manufacturer's guidelines and consult with a qualified engineer or contractor for the appropriate selection and installation of PVC water stoppers based on the specific project requirements.
