Yes. For uneven floor variances greater than 1/4″, we recommend first using a concrete self-patching compound or a similar liquid concrete patching product. For floor variances less than 1/4”, we recommend DRICORE® leveling shims.
To check for floor height variances, take a 4ft level or longer straight edge and place over the concrete surface where the installation is to take place. Raise the straight edge or level to the level line and measure the height difference between the concrete floor surface and straight edge with a measuring tape. Mark the spots on the concrete floor where liquid leveling is required and fill in as necessary.
