Radbar® 300 µm Radon Gas Barrier
BBA Agrément Certificate
Certificate type
A passive gas control system manufactured blown polythene, mono layer film produced from virgin polymer.
Radbar 300 μm Radon Gas Barrier is a safe solution to prevent the ingress of radon gas when used in the construction of buildings and dwellings. Radon barriers provide significant protection and are relatively cheap to install in new buildings, being in effect an enhanced gas tight dpm. They are also much cheaper and less intrusive than radon remedial measures used for existing buildings. It is therefore prudent to provide them where there is any reasonable indication that a site has enhanced radon potential. In addition, someone purchasing a new property will expect their new building to be protected against radon if it is in an area at risk. Providing protection in borderline cases reduces the need to explain why measures have been omitted. The Building Regulations (E&W) require that proper precautions be taken to prevent danger to health and safety when building on gas contaminated land. When installed in accordance with the BRE report 211 'Guidance on protective measures for new buildings' which supports Building Regulation Approved Document C2 (2004) and Approved Document L (2007), Radbar is an effective solution to the problem and can be laid with confidence.
The Radbar Radon System consists of a membrane extending the whole of the floor and walls. The system should incorporate an underfloor ventilated sump or sumps, which can be subsequently converted to an active system by use of suitable ventilation fans. Radbar radon resisting membrane when installed in accordance with the BRE and NHBC recommendations, will also act as a damp proof membrane to protect the building against the ingress of moisture from the ground.
