Chicago and the surrounding suburbs have some of the highest radon levels in the country. A concrete floor in the crawlspace will mitigate the problem in your home. The American Lung Assocation and The E.P.A (Environmental Protection Agency) recommend a concrete floor and proper drainage be installed in all existing crawlspaces.

How radon gets in to your home: 1. Unfinished crawlspace 2. Construction joints 3. Cracks in walls 4. Gaps in suspended floors 5. Gaps around service pipes 6. Cavities inside walls 7. Cracks in solid floors
