    Abstract: A stress-free embossed, ornamented surface covering, suitable for use as a floor or wall tile, is made by: providing a decorated resinous film on a release carrier, with the decorated surface of the film facing away from the carrier; providing on a release carrier a pre-formed, low-density, reinforced, porous thermoplastic base material, which may include hollow, non-thermoplastic particles; interfacing the decorated surface of the film with the top surface of the base material; perforating the film, after removal of the release carriers; and, subjecting the structure to high frequency electrical energy and pressure in a flatbed press having a cooled embossing plate and a cooled back-up plate, to emboss the structure, fuse the resins and render the film substantially impermeable.
