Application

Suitable for use on sites with radon, carbon dioxide and methane ground gas. Protects against the ingress of hydrocarbon vapours where it is separated from the ground, e.g. above a block and beam floor.

Description

A flexible, loose-laid gas barrier.


The barrier incorporates a two-layer low density polyethylene membrane with a polypropylene reinforcement grid and an aluminium foil core. Extremely flexible for ease of installation and robust to cope with site conditions.


Features and benefits:

  • Gas-proof against radon, carbon dioxide, methane and other contaminants.
  • Protects against damp, acting as a damp-proof membrane (DPM).
  • Can be laid on sand blinding, Delta Protech Geotextile Protection fleece or a smooth concrete finish.
  • Can be patch-repaired.
  • Laps can be joined together either by using a 50 mm Delta Gas Barrier butyl tape or welding by on-site contractors.
  • CE-marked and BBA-certified.
