Can new properties be protected from radon?
Barriers (membranes) which are impermeable to radon can be laid across the footprint of a building during construction. It is important that these are installed by trained specialists, and not general groundworkers, as any gaps or splits in the material will allow the gas to pass through and can render the membrane useless. The current Building Regulations require newbuilds in certain parts of the country to incorporate radon protection.
