Prodex Under Concrete Insulation will make the basement floor warmer. Prodex is an effective barrier against the upward migration of radon through joints, cracks and other openings in the building foundation into your living space. Radon is radioactive gas found in soils, rock and groundwater. It is formed by natural decay of radium and uranium isotopes. Radon levels vary depending on the geologic makeup of your location. Radon is naturally emitted from the ground where it is diluted to an insignificant level by the atmosphere. Inside a sealed and insulated building, radon can concentrate into high and potentially dangerous levels.
