ECA PVC Waterstops are made by high-grade Polyvinyl Chloride (PVC) resin extrusion compound that are plasticised and stabilized to offer long life, performance, existence to abrasion and attack by ozone, oxidation, alkalis, hydrocarbons, corrosions, waterborne chemicals and aging. The cross section configuration features a multi rib design for an effective anchor to the concrete a flexible, and a hollow center bulb to accommodate moderate expansion and contraction. ECA PVC Waterstops is flexible, resilient, chemically inert, is not affected by weathering, low temperatures, or constant immersion in water, unaffected by concrete additives and most water solutions of organic chemicals. It has abilities to accept joint movements and the same time prevents water passage through the joints. ECA PVC Waterstops are manufactured to meet the most stringent performance specifications. This is achieved by offering excellent inherent technical characteristics within the product.
ECA PVC Waterstops are designed to provide an integrated sealing system for construction and expansion joints and differs from actual sealants in that it is already installed in its pre-planned position when the concrete is poured, taking up its function as flexible watertight as soon as the concrete has hardened. ECA PVC Waterstops are specially designed to provide an integral sealing system for water retaining and water excluding concrete structures such as:
Water Retaining Structures:
• Sewage Tanks
• Drainage Canals
• Water Reservoirs
• Swimming Pools
• Water Reservoirs
• Swimming Pools
• Dams, Canals, Culverts
• Water Treatment Plants
Water Excluding Structures:
• Foundations, Basements
• Roof Decks
• Tunnels
• Pumping Stations
• Underground Chamber/Car Parking
• Subways
• Bridges
• Retaining Walls
• It is totally free of defects in material handling and workmanship and also it will not brittle or crack due to normal exposure.
• Normal water control applications in shore A-hardness will not effect to its characteristic.
• This will resists normal abrasion and tear failures.
• It will not fail under normal expansion and contraction in joints if it is installed in a professional way as mentioned in application method. Multi-rib design for an effective grip and also provides totally effective water barrier.
• Reinforced edge flange with brass eylets allows easy wiring to the reinforcement.
