I am currently removing an old wood floor from an old house and putting it in my new house. I have two concerns with how to install the new floor. My house is a slab on grade and I’m assuming there isn’t a vapor barrier below the slab. This makes me a little leary of installing the wood right on the slab cause I’ve seen what can happen in that case and I don’t want cupped floors. The other concern is that I’ve broken some of the tongues a little bit and I’m wondering if there is a way to still install these without always worrying if it’s going to move. I was thinking about just placing a vapor barrier or sound deadener on top of the slab and just glueing the wood together but I would like to know if there’s a better option out there.
Thanks to anyone who can help.
