Radon Gas Membrane
This high quality Radbar radon membrane offers protection against cancer-causing radon gas. It also acts as a damp proof membrane in situations where there is no hydrostatic pressure.
Manufactured using only top grade virgin polymerto ensure consistency and quality, these radon gas membranes are used widely across the UK and Europe. They protect homes by preventing harmful gases from seeping into properties. They are extremely durable, highly-puncture resistant, and have superior elongation properties compared to reinforced products.
Permagard supply 4M x 25M rolls that are designed to be easy to install, while reducing the use of tape and sealants required for jointing.
Installation of Radon Membranes
Radon gas membranes need be installed by professionals in accordance with BRE 211:2007. They are designed for concrete ground floors and can be installed either above or below the slab. They are suited to the following applications:
• reinforced concrete floors that have been cast in-situ
• suspended beam-and-block concrete floors
• precast concrete slabs
The radon gas membrane should extend the whole of the floor and walls. Make sure that it is laid on a smooth surface or one that has been sand blinded to prevent any punctures. It is vitally important that all joints are sealed including under walls and to gas DPCs. Two sections of membrane will require Radbar Double Sided Tape between the joint and Radbar Single Sided Tape Grey (Radon) over the joint.
You should also take measures to protect the radon membrane once it is laid. You can either cover the entire area with some form of temporary boarding or through the immediate laying of a floor screed.
