Applications

• P.V.C WATERSTOP is produced in different shapes and sizes and is used in concrete construction to prevent the passage of water through expansion or construction joints.
• Swimming pools and reservoirs
• Foundations
• Water tower dams, Tunnels, canals
• Water and sewage treatment plants

Advantages

• High flexibility at low temperatures
• Exceptional resistance to water, UV-Rays, seawater, alkali and chlorine
• High tensile strength
• Many different types and sizes

Waterstop Selection

• The waterstop is selected according to the Type of joint, thickness of concrete, the movement of joint and water pressure.
• Generally the thickness of the concrete should be greater than or equal to the width of the waterstop profile. In addition the width of the waterstop be at least 6 times greater than the largest size of the aggregates.

Types of Waterstop

Preparation and Placing

• The surface of the waterstop must be clean and oil free to have Maximum bonding to concrete
• Use hog rings crimped between the last two ribs and wire tie the waterstop to the reinforcing steel.
• Install in the center of the joint, with half of the width embedded in the concrete on each side of the joint.
• In expansion joint, take care during the concrete placement to keep the center bulb unembedded and in the center of the joint.
• It is made of thermoplastic P.V.C therefore can be welded by use of welding blade, the waterstop can be heated (200°c- 250°c) until the material gets plastic, and then pressed together
