Sandhyaflex India Private Limited - PVC Hand Rail

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. Then, the other half is embedded that leaves the centre bulb free for expansion and contraction movements. Applications Of PVC Water Stoppers Public Utilities: For bridges, road embankments, tunnels, water tanks, water filtration systems, swimming pools, sewage plants, clarifiers, dams, canals, reservoirs, aqueducts and irrigation projects cooling towers.   Buildings: For basements, foundations slabs, masonry joints, retaining walls, terraces, overhead & underground water tanks and   Industries: For fertilizer steel, chemical plants, waste treatment plants, atomic reactors, thermal & hydro power stations and shipyard & docks. Precautions to take while water stopper installation They are vulnerable to damage during the construction process   The concrete compaction around the water stopper should be taken care of. If not, it can dislocate and lead to a risk of honeycomb formation. This might result in leakage through concrete instead of the joint. Methods for joining PVC water stoppers with heater blade Water stoppers can be joined on the site using a simple electrical heater blade.   Water bars having the same width and design should be sharply levelled with a knife at the   Turn on the Electric Heater Blade. Wait till it becomes hot   Place the water stopper on both sides of heater blade. Press it until it melts but without burning   Remove the heater blade upward   Join the molten ends quickly. Hold them together firmly for approximately 20 to 30 seconds.

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
