It happens to thousands of homeowners each year - the sale of their home falls through because of high radon in their basement. They have to hustle to get a radon mitigation system installed and hope that the buyer will not walk away. But for many years after, they may wonder about the long-term effects of the radioactive gas on their children.
The leading penetrating concrete sealer for the preservation and protection of concrete blocks, commercial and residential concrete since its inception in the late 1990s.
