PVC Water Stopper

PVC Water Stopper :

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.

Application in construction industry

  • PVC water stoppers effectively seal and concrete joints, preventing water seepage.
  • They can withstand expansion and contraction movements at the joints without compromising their sealing capabilities.
  • PVC water stoppers accommodate displacement and deflection caused by temperature variations, differential settlement of foundations, and seismic forces.
  • The watertight seal eliminates the risk of cracks and ensures the structural integrity of the construction joints.

Selection of appropriate PVC water stopper

  • Ribbed Type – It is specially designed as a multi-purpose water stopper, which is used for the expected differential settlement of poured concrete and ensures a firm grip with the surrounding concrete, providing stability and preventing displacement of the water stopper.
  • Dumbbell Type – Dumbbell-type water stoppers are recommended for situations with a significant variation in temperature, leading to expansion and contraction of joints. These water stoppers are designed to accommodate these movements effectively, ensuring a reliable seal and preventing water seepage.
  • Kicker (Surface Type) – In cases where embedded water stoppers are not feasible due to the interference of steel reinforcement, kicker or surface-type water stoppers are utilized. These water stoppers are placed externally on the surface of the structure to provide a barrier against water seepage, overcoming the limitations posed by the presence of steel reinforcement within the concrete.

Installation procedure:

The water stoppers are secured to the steel structure during installation using tiny wires that are threaded through the eyelets. Additionally, metal clamps are used to hold the water stop seal firmly in place. Usually, the installation requires a step-by-step process.

The water stopper is first partially inserted into the concrete, extending the other half. This initial positioning guarantees a solid connection with the concrete building. Movement and flexibility are possible because of the expanded half.

After that, the other half of the water stopper is inserted into the concrete, being sure to leave space around the centre bulb for expansion and contraction motions. With this arrangement, the water stopper may adapt to structural changes and temperature-related changes without losing its ability to block water effectively.

Applications of PVC Water Stoppers

  • Public Utilities: For bridges, canals, aqueducts, water filtrations systems, water tanks, tunnels, road embankments, swimming pools, sewage plants, reservoirs, clarifiers, dams, and irrigation projects cooling towers.
  • Buildings: Basements, retaining walls, foundations slabs, terraces, masonry joints, overhead & underground water tanks.
  • Industries: For fertilizer steel, waste treatment plants, chemical plants, shipyard & docks atomic reactors, and thermal & hydropower stations.

Precautions to take while water stopper installation

  • They are susceptible to damage during the construction process.
  • Proper compaction of concrete around the water stopper is crucial to prevent dislocation.
  • Inadequate reduction can lead to the formation of honeycombs, creating porous areas in the concrete.
  • Honeycombing increases the risk of water leakage through the concrete instead of the intended joint.
  • Careful handling and correct compaction techniques are essential to maintain the effectiveness of water stoppers and prevent water seepage through joints.

Methods for joining PVC water stoppers with heater blade

  • Make sure the water bars that will be connected are the same width and style. To level them, use a knife sharply.
  • Once it reaches the proper temperature, turn on the electric heater blade.
  • Place the water stopper so that it melts but doesn't cause burning on either side of the heater blade.
  • In an upward motion, carefully remove the heating blade.
  • Make sure the water stopper's melted ends are properly aligned before quickly joining them together. For 20 to 30 seconds, tightly clasp them together.
