Visqueen Radon R400 Membrane is manufactured from an enhanced blend of polymer films that is suitable for use in the protection of buildings from the ingress of radon gas and vapour.

Visqueen Radon Membrane is also a gas, vapour and damp-proof membrane but is not intended for use where there is the risk of hydrostatic pressure.

Visqueen Radon Barrier Membrane and ancillary components must be used in accordance with the recommendations in the most recent edition of the Building Research Establishment Report BR 211:2015.

Radon Membrane can be used in most common floor constructions. It is installed in a similar way to a damp proof membrane, but with much greater attention paid to workmanship and detailing in order to achieve effective sealing at all locations.

Apply the Visqueen Radon Barrier Membrane

Visqueen Radon R400 should be installed on a smooth continuous surface e.g., grouted beam and block floor, a compacted blinding layer e.g., 50mm thick sand blinding, or smooth concrete blinding. The substrate should be free from irregularities such as voids or protrusions. The membrane can be cut with a sharp retractable safety knife or robust scissors.

  1. Ensure the substrate is clean and dry.
  2. Lay the Visqueen Radon R400 on the substrate.
  3. Joints should be overlapped by at least 150mm.
  4. Airtight seals should be formed around all service entry points.
  5. Cover the membrane as soon as possible with a 50m screed after installation to prevent damage. Care should be taken to ensure that the membrane is not punctured, stretched or displaced when applying a screed or final floor covering.
  6. Where there is a high risk of potential damage, the membrane should be covered with Visqueen TreadGUARD protection, screed, or other approved protection material before positioning the reinforcement.
