Storage and Handling

Store in a dry and clean environment in its current packaging. The waterstop adhesive has a maximum 9 months shelf life from production date in its original unopened cartridge.

Preparation

Cast in a channel 20mm wide x 12.5mm deep. Ensure that the cast channel is free from loose friable material and free from contamination such as dust or sand. Ensure the surface and working area is not water logged.

Installation

For both vertical and horizontal applications and to ensure the integrity of the system we recommend using Visqueen Waterstop Adhesive. Apply the adhesive using a sealant/caulking gun along the channel. Optimal fixation is achieved when the full contact area of the waterstop is covered with adhesive. 1 Cartridge covers approximately 8 linear metres.

After application of the adhesive, the waterstop needs to be pressed down, to ensure full contact with the paste underneath and to achieve optimal adhesion.

To ensure a continuous section of the sealing waterstop, an overlap of 50mm to 10mm is applied and the bar ends are firmly pressed together. A minimum concrete coverage of 70mm - 80mm on each side is required.

Once applied, pour concrete over the exposed Visqueen VX25 Waterstop within 2 days.

Usable Temperature Range

It is recommended that Visqueen VX25 Waterstop and other system components should be installed between 5°C to 25°C.

Additional Information

The product must NOT be used in expansion joints.

Do not install during heavy rainfall, as it may result in swelling before the concrete has been poured on the sealing bar. Avoid all contact with water before concrete casting.

Any vertical applications above 1200mm please contact Visqueen technical team.
