I was a comercial applicater of both Urathane and Eurea- Formaldahyde Foam back in the late 70's. I believe the EPA took Eurea-formaldahyde off rhe market. The Urathane was done mostly on roof applications and then a plastic sealant was sprayed on top as a sealant against moisture. You mighrt try some commercial roofing contracters to see if there is somebody still useing this process.We did build some walls with it to make our warehouse larger. I believe the cost of the application was somewhere around $2.50 Sq. Ft. back then.
