Ceramic ground-covering elements comprise anti-frost ground tiles (1) which are bonded by means of a special mortar (2) on a support layer (3) made of closed-cell rigid foam. The thickness of the special-mortar layer is adapted to the thickness of the ceramic ground tiles and to the loads which are to be expected. The thickness of the support layer can be altered according to requirements. The support layer (3) is provided on the underside with a coated glass-fibre cloth (4) which is embedded in a special-mortar layer (5). The outer dimensions of the support layer can be larger by up to half a joint, on all four sides, than the actual tile format. A joint which can later be filled is thus predetermined. The processing method for laying the elements is as follows: the ceramic covering elements are laid, so as to be level in terms of height, by means of a viscoplastic bedding mortar (6) on so-called substructure plates (7) which comprise closed-cell rigid foam. The substructure plates must be laid so as to be centred under the joint intersections, with the result that all four ceramic covering elements in the region of the joint intersection have a uniform bearing surface. The ceramic ground-covering elements can be laid so as either to be jointed or not. If the elements are not jointed, the format of the support layer can only be as large as that of the tile. If the elements are to be jointed, then the format of the support layer must be larger than the format of the ceramic ... Original abstract incomplete. <IMAGE>
