Had a post last month asking if anyone has used a product called Radonseal. Had a response telling me to do a search for radon on this forum, but could not find anyone saying anything about Radonseal. Would like to know if it was worth doing? And if anyone has used it. They say that its a Waterproofing,
Damp-proofing, Radon mitigation, Concrete preservation, that you spray on walls and floor that are below grade. Click on link below to see web page talking about the product.
