Hello everyone, I'm about to set my forms today and the guy pouring my floor suggested I use "foundation foam" that is 16psi and cut out holes where my 4 post lift will go to act as footers, the foam is what they use under residential basement floors and is half the price of C-300 pink but I'm uneasy about this idea. I feel like I should just spend the money on 2" FOAMULAR C-300 @ 30 PSI and keep it continuous with no voids for footers since I live in the north. Is there a third product I'm not considering?
