Application

  • Used with below ground reinforced concrete structures such as basements, retaining walls, lift pits and car parks.
  • The barrier also prevents the ingress of harmful levels of volatile organic compounds and hazardous ground gases. 

Description

A pre-applied membrane, manufactured using Visqueen’s advanced barrier technology and designed to comply with current guidance on waterproofing, and protection against Volatile Organic Compounds (VOCs) and ground gases. The product is textured on one side to aid adhesion to cast in-situ concrete and available in a large roll format to minimize jointing and for quick installation.


Features and benefits:

  • Conforms in full to BS 8102:2022, CIRIA C748 and BS 8485. CE marked (EN 13967).
  • Unique pre-applied and gas resistant membrane.
  • Excellent VOC and methane barrier resistance.
  • Suitable for both tanking and DPM applications.
  • Exceptional puncture resistance, no protection required.
  • Welding and Visqueen Gas Resistant tape system options.
