List of featured suppliers of DAMPCOURSES Radon Resistant on Building Products Index
A dampcourse or damp proof course is a barrier that is placed in a building's walls or floors to prevent moisture from penetrating the structure. It is usually made from materials such as bitumen, plastic, or lead, and is installed at the base of walls or above ground level to prevent rising damp. Radon resistant dampcourses are installed in areas with high levels of radon gas to prevent it from entering the building. These dampcourses are made from materials that are resistant to radon gas and are installed in a similar way to standard dampcourses.
