Hardwood installed directly on slab

Moved into our house last year and have been having issues with curling and buckling with the oak hardwood installed on our ground floor. Wood is installed directly to the slab with construction adhesive so it's no wonder we have issues. Ideally I would want the flooring installed on sleepers with a vapor barrier between the two and am willing to do this but what happens with my (4) exterior doors whose thresholds are installed on the slab also? Would I need to remove each one and modify each opening up 3/4" to adjust for the new subfloor/sleepers? All exterior doors are metal so I don't have a trimming option. Can I apply a vapor/moisture barrier directly to the slab and put new floors down and keep the doors where they are? Anyone ever come across this?

Hardwood can be installed on slab if there is no moisture issues.Did they check for moisture before floor was installed? Doors will be a large problem to move.

You will need a hardwood adhesive that is also a moisture barrier... costs extra but it can be used on concrete floors.

Construction adhesive is the wrong choice.

You obviously have moisture problems, so think hard about wanting to put hardwood down again. If you choose that hardwood route, choose a floating floor that has a vapor/moisture barrier underneath it. Run the moisture barrier up the wall several inches and bury it behind the baseboard. This way you create a inverted pool to keep moisture from getting to the wood, but allows an avenue for escape.

Take a look at vinyl strip flooring.
Looks like wood, easy to install, 100% waterproof.
The stuff I have in my bathroom and kitchen was sort of like a snap Lock.
Only tools I needed was a hand floor roller and big metal snips to cut it to length.
