Re: cupping hardwood floors
There's a moisture issue that needs to be corrected. Doesn't mean there's a water issue but could be from temperature differential between the slab and room temperature creating excessive condensation. I'll bet if the some flooring is removed there are signs of moisture on top of the vapour barrier covering the concrete.
The floor boards are toast ---- trying to repair them doesn't sound like a reasonable approach.
