Waterproof Cork can be installed on top of most hard surfaces such as resilient floor coverings and ceramic tiles which are sufficiently fixed, completely leveled and have no loose areas. The maximum grout line (joint) should not be wider than 2mm (0.08�), and 1mm (0.04�) depth. If this is not the case, or if there is any kind of embossing, then you should skim coat the grout lines with a floor leveler. Concrete and ceramic tile subfloors must be even, dry, and deflection (dips or bumps) should not exceed .20 inches in 6.6 feet (5mm in 2m). Installations below grade or at grade on concrete or tile require a waterproof barrier in the form of 6ml polyethylene plastic (perm rating of .1). Installing above grade, however, does not require a vapor barrier. Entire installation document can be found here : https://772072.app.netsuite.com/core/media/media.nl?id=1740812&c=772072&h=27678
