Browse Forums Flooring & Floor Covering 1 Jul 14, 2023 6:42 pm Hi Everyone, Ripped up the carpet and the surface below has come loose and you can see the slab below. The material breaking away looks and feels like crumbling cement. Any idea what it is? Do I need to repair the surface or could I pull it all up and lay carpet on the slab below?
