Airtightness of Concrete Basement Slabs
Radon is a radioactive gas known to be a major cause of lung cancer. It enters houses from the surrounding soil, primarily through cracks in basement floors and walls, as well as pipe penetrations. To reduce the level of radon in a house, two approaches can be taken. One is to depressurize the sub-slab volume, with a sub-slab suction system. Alternatively, the floor can be made more airtight, which requires more than simply caulking and sealing the basement floor from the inside. A project was undertaken to evaluate the effectiveness and economy of using polyethylene film to make concrete basement slabs more airtight.
