We are working on the application of expandable foam in a ten foot section of 3' diameter duct that is located underground from the 232-Z building at PFP. The rest of the duct will be filled with grout but we want the last ten feet that will press against a plastic cover to be less weight. We are concerned that the expandable foam will collapse if it's not exposed to air and return to the liquid chemicals. Do you have any advise?
