Application

Suitable for wrapping attenuation tanks and other VOC geomembrane applications such as lagoons, canals, artificial lakes and contaminated cut-off trenches.

Description

A multi-layer thermoplastic geomembrane suitable for attenuation tanks and permeable paving systems where hydrocarbons and volatile organic compounds (VOCs) exist and a VOC decay resistant membrane is required.

When used as part of a Type C porous paving system, the membrane adds extra security as it will not suffer from erosion from the passage of hydrocarbon or VOCs from the surface above the product. In normal backfilling applications no additional protection is required, however in demanding applications, Visqueen TreadGUARD 300 should be used. Pipe penetrations should be over sealed with the Visqueen 300 mm detailing strip.

The membrane is grey in colour, 1 mm thick and supplied in 2.44 x 41 m rolls.

Features and benefits:

  • Conforms to Appendix C of CIRIA C697, C753 and C748.
  • Protects against hydrocarbon and VOC liquids and vapours.
  • Excellent welding characteristics.
  • Excellent tear and puncture resistance under high compressive loads.
  • Suitable for radon applications.
  • Can be used in SuUDS Type C porous paving infiltration systems and attenuation systems.
  • Available in eEasy to handle roll format.
  • CE Marked to EN 14909.

Applications:

Suitable for wrapping attenuation tanks and other VOC geomembrane applications such as lagoons, canals, artificial lakes and contaminated cut-off trenches.
