I used it on my field stone foundation. I believe, mine was the Foamo Foam with flame retardant http://www.fomofoam.com/
I think, it worked real good to reduce cold and dampness associated with the field stone. I didn't apply it as heavy toward the bottom, as it was claimed, the old foundations depended somewhat on heat getting out to prevent frost from pushing the foundation. You can see some of my foundation insulation on the links below of the "coal bin" or the "return air".
