Radon Gas is a naturally occurring radioactive gas that comes from radium deposits in the earth’s crust. If present in the soil under your home, it can get sucked into your house via the basement or crawl space.
DON’T PANIC! It’s fairly common and easy to get rid of.
Some people that know “a little”, think that basement waterproofing systems and radon mitigation systems are incompatible. While it is true that gaps, cracks and hols in the basement floor and walls need to be sealed as part of the strategy to get rid of Radon, this can be done without compromising the waterproofing system.
