I'm just looking for the pro's advice on this one. So your input would be appreciated. Would it be possible to blow closed cell foam on a foundation below grade for waterproofing and insulation value? I suppose we could use block for the example. I could just build an ICF foundation and be done with it but I'm exploring my options.
Truthfully, it depends on a host of items - but in this case I would go with ICF & a waterproofing applied to the outside of it
Better costs, less chance of issues or mistakes, etc...
