Excellent Sealing and Waterproofing Performance
PVC waterstop
It is made from polyvinyl chloride resin and many kinds of chemical additives. It has excellent elasticity and sealing performance. It is resistant to corrosion and it has high tensile strength. PVC waterstops are widely used for dams, bridges, tunnels, culverts, canals, water reservoirs, swimming pools, waste water treatment plants, retaining walls, basements and foundations.
EVA waterstop
It is made from polyvinyl chloride, EVA resin and many kinds of additives. It is widely used for various concrete structures for liquid leakage and permeation prevention, such as basements, retaining walls, dams, bridges, tunnels, culverts, storage tanks, swimming pools, water reservoirs and waste water treatment plants.
Rubber waterstop
It has good elasticity and it is highly resistant to abrasion, corrosion, chemicals, aging and tearing. It is suitable for the temperature range of -45 °C to +60 °C. It can be manufactured from many kinds of materials, such as natural rubber, neoprene, nitrile rubber and EPDM. Rubber waterstops are widely used for dams, bridges, tunnels, basements, foundations, storage tanks, waste water treatment plants and water reservoirs.
Steel-side waterstop
It is the modification of rubber waterstop and it can adhere to concrete firmly thanks to the galvanized plates. So it can bear strong water pressure without displacement. It is composed of two parts: strength part and waterproofing part. Strength part is made from galvanized plates, making waterstop adhere to concrete firmly. Waterproofing part is made from rubber, such as natural rubber, neoprene, nitrile rubber and EPDM, making waterstop have excellent elasticity. Steel-side waterstops are mainly used for dams, culverts, bridges, tunnels, basements, retaining walls, water reservoirs, swimming pools, storage tanks and waste water treatment plants.
Swelling waterstop
It is made from rubber waterstop and swelling waterstop bars, which can enhance the tightness between waterstop and concrete surface. So it has better waterproofing performance than other waterstops. They are mainly used for dams, bridges, tunnels, culverts, canals, basements, retaining walls, swimming pools, water reservoirs and waste water treatment plants.
