Spalling foundation and rigid foam application
My old home has an old poured concrete foundation in part of it and a fieldstone foundation in another part. The plan was to CC SPF the entire thing until I got the estimate….holy inflation Batman! A conditioned basement is the goal.
The concrete portion has a spalling effect, where chips and dust fall off the walls. The basement is very dry otherwise. Would it be ok to use rigid foam on the concrete walls even though are spalling? This could save a bunch of money over CC. I would use CC SPF on the fieldstone anyway.
I am planning some kind of Delta FL type flooring treatment with vinyl plank flooring, if that matters.
What do you guys think?
