I recently bought a house, and one of the rooms has a tile floor. The house is from the 50's. This tile is cracking and breaking up, and many tiles are missing.

I would like to put laminate flooring over the tile. Underneath the tile is the concrete foundation(the house is built on a slab, so no basement (it sucks)). I'm taking a wild stab at figuring out how to install this, but shouldn't I put down a vapor barrior to prevent moisture from entering from the concrete? I'd think that over time the moisture and humidity from the concrete slab will destroy and warp the flooring. Any help or ideas is helpful

thanks
