Radon Membrane 400mu 1600 Gauge - 4m x 20m

Radon Barrier Membrane (Red)

This high quality 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 from virgin polymer to ensure consistency and quality, these radon barrier membranes are extremely durable, highly-puncture resistant, and have superior elongation properties compared to reinforced products. They are highly effective at preventing harmful gases from seeping into properties. 

At Permagard, we supply 4m x 20m multi-folded rolls that are easy to install, while reducing the use of tape and sealants required for jointing.

Applications

Radon Membranes are designed for concrete ground floors and can be installed 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

Note: These radon membranes are suitable for both basic radon protection and as part of a full radon protection system.

Installation of Radon Membranes

The radon membrane should extend the whole of the floor and walls. Make sure it is laid on a smooth surface or one that has been sand blinded to prevent any punctures. The membrane can be cut to size with a sharp retractable knife or a pair of high quality scissors.

Jointing

It is vitally important that all joints are sealed including under walls and to gas DPCs. Two sections of membrane will require PermaSEAL Double Sided Tape between the joint and PermaSEAL Single Sided Tape Grey (Radon) over the joint.  An overlap of at least 150mm is required for all joints. You have the option to heat weld lap joints with less overlap.

You should 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 by immediately laying a floor screed.

Complete Traceability

All rolls of this radon gas membrane are uniquely labelled and registered for complete traceability. This means that they can be installed safe in the knowledge that the product has been independently tested, certified and carries ISO9001 approval.
