NEW Radon Protection Requirements – Update -July ‘23 Guidance

Following the recently published BRE BR 211 2023 edition titled ‘Radon – Guidance on protective measures for new buildings’, its guidance should now be followed as it supports Building Regulations for all UK nations, and it has prompted the NHBC to release NHBC Technical Guidance 4.1/01 (July 2023) (Third issue) – Radon barriers.

The outline requirements for radon gas protection measures now advise the use a membrane of 400 µm or above according to construction conditions identified by the design. The NHBC Technical Guidance will be subject to a transitional period until entry in the 2024 standards Chapter 4.1 where gas barrier membranes <400µm will not be accepted when NHBC Buildmark Warranties are required.
