I have a 12" wide concrete foundation over 30 years old and cracked after 10 years.I am concerned about radon, will this seal air tight? Flexable?


I did call the manufacturer directly and they could not answer any more than what was on the label. So much for customer service use!!

Hello. In regards to this question, please contact the DuPont Contact Center at 866-583-2583 for further assistance. GREAT STUFF(TM) Insulating Foam Sealant is an air barrier, however, we would like more information on the application before giving further instruction.
