PVC Water Stopper

Selection of appropriate PVC water stopper Ribbed Type – It has a multi-purpose water stopper design to be used for the expected differential settlement of poured concrete and a firm concrete grip desired.   Dumbbell Type – With greater variation in temperature, expansion and contraction of joints happen. Dumbbell type water stoppers are the suggested ones for these cases.   Kicker (Surface Type) – Where the embedded types cannot be used owing to interference of steel reinforcement, these are placed externally. Installation procedure: During installation, using small wires, the water stoppers are tied to the steel framework through the eyelets. Also, certain metal clamps are used to grip the water stop seal and keep it in proper position. Initially, half of the water stopper is places in the concrete. It leaves the other half extended.

It is commonly used to provide a watertight seal and protect the structure from water damage. PVC water stoppers are typically made from high-quality polyvinyl chloride (PVC) material, which is durable, flexible, and resistant to water and chemicals. They come in various shapes and sizes to accommodate different types of joints and applications. The most common shapes include "dumbbell" or "center bulb" profiles, which provide effective sealing against water ingress. Installation of PVC water stoppers involves embedding them in the concrete joints before pouring the concrete. The water stopper is placed in the joint, and concrete is poured around it, ensuring a tight seal. The flexibility of the PVC allows it to accommodate slight movements or vibrations without compromising the water seal. PVC water stoppers are preferred over traditional alternatives like rubber or metal due to their excellent chemical resistance, cost-effectiveness, ease of installation, and long-term durability. They are also available in different grades to meet specific project requirements, such as resistance to hydrostatic pressure or chemical

It is designed to create a watertight seal and protect the integrity of the structure. Here are some key details and features related to PVC water stoppers: 1. Material: PVC water stoppers are made from high-quality polyvinyl chloride (PVC) material, which is known for its excellent durability, flexibility, and chemical resistance. PVC is resistant to water, chemicals, and environmental factors, making it suitable for use in various water containment applications. 2. Types: PVC water stoppers come in different types and profiles, depending on the specific application and requirements. Common types include straight PVC water stoppers, bulb-shaped water stoppers, ribbed water stoppers, and external water stoppers, among others. Each type has its unique design and features to cater to different sealing needs. 3. Design and Structure: PVC water stoppers are typically designed with a combination of rigid and flexible sections. The rigid sections provide stability and anchoring within the concrete structure, while the flexible sections allow for movement and accommodate joint e

A PVC water stopper, also known as a PVC water stop or simply a water stopper, is a specialized construction material used in civil engineering and building construction. It is designed to prevent the passage of water through joints or openings in concrete structures, such as expansion joints, construction joints, or penetrations, to ensure water-tightness and protect against water infiltration. PVC water stoppers are often used in applications where concrete structures are exposed to water, such as in dams, reservoirs, tunnels, swimming pools, basements, and underground construction. Here are some key features and uses of PVC water stoppers:

**Key Features:**

1. **Material:** PVC water stoppers are made from high-quality polyvinyl chloride (PVC) material. PVC is chosen for its durability, flexibility, resistance to chemicals and corrosion, and long service life.

2. **Design:** These water stoppers are typically designed as strips or profiles with varying shapes, such as "T," "I," or "X" shapes, to accommodate different types of joints and structural configurations.

3. **Flexibility:** PVC water stoppers are highly flexible and can adapt to the movement and expansion and contraction of concrete structures without compromising their effectiveness.

4. **Resistance:** They are resistant to water pressure, chemicals, and the corrosive effects of aggressive soils, making them suitable for a wide range of construction applications.

5. **Installation:** PVC water stoppers are installed within or along the joints of concrete structures, creating a physical barrier to prevent water infiltration. They are often embedded or cast into the concrete during construction.

**Uses:**

1. **Concrete Structures:** PVC water stoppers are commonly used in various concrete structures to maintain water-tightness, including dams, reservoirs, canals, bridges, tunnels, and underground parking structures.

2. **Swimming Pools:** In the construction of swimming pools and water tanks, PVC water stoppers are used to create water-tight seals around joints and connections.

3. **Basements:** When constructing basements or underground structures, water stoppers help prevent groundwater from seeping into the structure, ensuring a dry and moisture-free environment.

4. **Expansion Joints:** They are used in expansion joints to accommodate the movement and expansion of concrete structures while maintaining water-tightness.

5. **Retaining Walls:** PVC water stoppers are employed in retaining walls to prevent water from infiltrating behind the wall, which can cause erosion and damage.

6. **Underground Utilities:** These water stoppers can be used in underground utility tunnels or conduits to prevent water ingress and protect the integrity of utility lines.

7. **Tunnels and Culverts:** In tunnels and culverts, PVC water stoppers are crucial for sealing joints and preventing water from entering the structure.

Proper installation of PVC water stoppers is essential for their effectiveness. They should be selected based on the specific project requirements and construction conditions, including joint type, expected movement, and water pressure. Additionally, following industry standards and guidelines for installation and quality control is critical to ensure the long-term performance and water-tightness of the concrete structure.

Sandhya Enterprises are one of the leading manufacturers of PVC water stoppers. These water stoppers are flexible plastic stripes that act as a physical barrier to water. These barriers are commonly employed at concrete joints in basements, water-retaining structures such as structural foundations, water tanks and swimming pools, and other below-ground constructions.

A typical water stopper consists of two identical halves on either side of a central bulb. Increased path length made possible by this design effectively diverts any water that could try to enter past the water stopper's edge. Water stoppers increase their efficiency in preventing water penetration and preserving the integrity of the structures they are applied to by offering this extra extension. Sandhya Enterprises is dedicated to producing water stoppers of the highest calibre that adhere to industry requirements and provide dependable water barrier solutions.

Compounding of PVC Water Stopper

Our water stoppers are specially manufactured using an anti-ageing customized plastic compound. Additionally, it has PVC as a base polymer. These water stoppers offer several advantageous properties, such as high elasticity and tensile strength, immunity to corrosion, ensuring long-lasting durability even in harsh environments, and excellent weather resistance. They can withstand exposure to various chemicals, including acids, alkalis, metals, salts, and other corrosive substances. Other properties include lower water absorption, reducing the risk of water permeation through the joint. With their high hydrostatic pressure withstanding capacity, the water stoppers effectively resist water pressure, maintaining a watertight seal.

Moreover, the water stoppers are suitable for applications with dynamic loads or vibrations because they can endure strong turbine shocks. In times of earthquakes and flooding, they also show resilience, adding to the security. Sandhya Enterprises assures its water stoppers contain various qualities to suit the many demands of water barrier applications. It combines the anti-ageing customized plastic compound with PVC as the basic polymer.
