The tiles start peeling as the adhesive turns to a white powder. You buy a couple of energy-hungry dehumidifiers, but they draw in more moisture through the concrete making it more porous. People spend about 75 percent of their time at home. Pores in concrete also draw in moisture by capillary action. Your basement or slab is by far the single largest source of humidity in your home.
Humidity promotes molds and mildew, dust mites, bacteria and other biological contaminants.
Over a third of homes has mould or fungus growth. Radon gas is inert. When you inhale it, radon circulates through your body and organs, and you mostly exhale it again. Unfortunately, radon is radioactive and during its decay emits radiation, which causes cacer. Deep-seal the concrete against water and dampness.
