Application

  • Radon contaminated areas in accordance with Irish Agrément Board (IAB) certificate no. 05/0214.
  • Resistance to moisture in accordance with Technical Guidance Document C.
  • Above or below concrete floors in accordance with manufacturer's design specification.

Description

High performance, weldable co-polymer thermoplastic radon barrier. Manufactured as a flexible barrier membrane suitable for extreme conditions. The system provides complete protection, from sealing floors to walls, and complex detailing such as service pipe penetrations and corners.

Supplied in a large, single wound roll format, covering 50 m², to minimize jointing and installation times.

Features and benefits:

  • Formulated for ease of welding.
  • High flexibility and puncture resistance.
  • Enhanced toughness at sub-zero temperatures.
  • Greater impact strength than traditional reinforced radon membranes.

Applications:

  • Radon contaminated areas in accordance with Irish Agrément Board (IAB) certificate no. 05/0214.
  • Resistance to moisture in accordance with Technical Guidance Document C.
  • Above or below concrete floors in accordance with manufacturer's design specification.

Welding:

In general radon membranes that are less than 0.5 mm-thick, especially reinforced plastic, welding is difficult as the hot air devices used to bond the laps can burn through thinner materials. Welded joints when installed correctly are more robust and provide increased integrity and strength. It is recommended that specialist installers are used with the correct equipment such as manual and automatic hot air welders. Contact manufacturer for further information.

Approvals:

  • Irish Agrément Board (IAB) Certificate No.05/0214 – Radon Barrier System.
  • CE marked to EN 13967.
