Taking over my mother's house this summer. In '72, urea-formaldehyde foam was injected into the crawl space through drilled holes in the floorboards, and this has shrunk, crumbled, etc., making the floors against the outer wall cold.
It's incredibly cramped in the crawl space, so doing anything from that direction seems out of the question unless I hire seven small dwarfs. The options are either to tear up the tongue-and-groove floor from the late 1800s (according to my mom, it's been flipped once in the past) and redo the entire crawl space, or possibly use the cork-filled drill holes to inject polyurethane foam. The floor needs to be sanded anyway.
Any tips, ideas, or thoughts?

Haha I don't know what it looks like but could external insulation in connection with drainage be something? Or is it a nice brick foundation? Otherwise, there are probably only two options, either to send in the 7 little dwarfs with a vacuum truck or to continue with a half-working concept and use the old holes? Vacuum truck is expensive as f#% cost us 80,000 for 57 sqm with 3 different companies and a workweek and a bunch of gray hairs
