1. Natural Stone Foundation Older homes are often built on a foundation made out of natural stones like granite, limestone and other quarry rocks. These stones are formed together using concrete or other materials. Radon gas is created when certain rocks begin to decompose and erode. One such stone that has trace amounts of uranium is granite.
