Health experts are now concerned that crawl spaces may, in fact, be harmful to human health.
One problem is that crawl spaces can allow radon emitted from the soil beneath our homes to enter through our foundations. Radon is a naturally occurring gas that has no notable odor and comes out of the soil when deposits of uranium begin to decay, which happens all over the earth all the time. When radon gets trapped inside our homes and the concentration of it begins to build, this is cause for concern.
There are lots of different methods for moisture control in crawl spaces, such as ventilation with outside air and crawl space encapsulation.
