Subsequently, drainage ducts (10) which are in connection with the adhesive-free sub-regions (9) and lead to at least one block end are produced in the region of the chipped-away area (6), on the adhesive layer (8), and a compensation mortar layer (12) is then applied, which mortar layer is covered, for its part, by a wear layer (13).
