Application

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.

Ribbed type water stop:

Used in construction joints where little or no movement is expected and the ribs provide better watertight sealing

O24

O30

Ribbed type with center bulb:

It is used in expansion, contra ion and construction joints, particularly where a large amount of movement is expected. The ribs provide better watertight sealing

EF30

Surface sealing strip for construction joints:

It is embedded with its external surface flush with the surface of the concrete element

OF30

Surface sealing strip for expansion joints

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
