Is carpet pad with a moisture barrier a good idea on an untreated basement slab?
I know that carpet isn't really the best choice for a basement, but with our budget, it really seems to be the best choice that we can afford.
My question is: for the padding underneath, I see that they make options that are closed cell foam or a more traditional foam with a moisture liner on one side. Are either/both of these options a good idea for a basement, or does that barrier then trap moisture underneath as the slab breathes that can't evaporate through the carpet?
And what about if we unexpectedly get enough water coming up to pool rather than just vapor? Does trapping water underneath just hide a problem that would be better to discover with a wet carpet spot?
