  • Excellent flexibility in cold weather conditions
  • Wide temperature welding range
  • High puncture and tear resistance
  • Easy to handle roll size
  • Manufactured in the UK

Typical applications

Visqueen High Performance UDG is suitable for a range of applications including underground attenuation tank encapsulations, permeable paving systems, porous sub-base installations, containment and cut-off trenches.

Visqueen High Performance UDG is a chemically inert membrane that exhibits superior welding properties, making it ideal for on-site welding of joints. In certain applications the sealing of laps can be achieved using the Visqueen UDG Jointing Tape System. In these instances Visqueen UDG Double Sided Jointing Tape is applied approximately 50mm from the edge of the membrane. The next width of Visqueen High Performance UDG should then be overlapped. For effective jointing all laps should be a minimum of 150mm. The lap should be secured with Visqueen GR Single Sided Lap Tape.

When ambient temperatures drop below 10°C, the components of the Visqueen Jointing Tape System should be kept in a warm, dry place until needed. Membrane installation using this technique is not recommended below 5°C. Always ensure that the membrane lap area is clean, dry and free from dust or contamination at the time of jointing.

Visqueen High Performance UDG should be installed on a blinded or smooth surface, free from sharp protrusions. Avoid areas of unsupported membrane. Adequate protection, such as Visqueen TreadGUARD1500 or 300, should be applied over the membrane to prevent damageafter installation.
