Multilayer structure for creating a floor or wall covering

Abstract

The invention relates to a multilayer structure for producing a tile or plank floor covering, the multilayer structure comprising a top wear layer bonded to a backing layer, said top wear layer defining a nominal surface, said top wear layer comprising a raised pattern extending to a maximum depth P1 from the nominal surface, said top wear layer having a groove opening onto an edge of the multilayer structure, the groove comprising at least two walls, including an edge wall and a bottom wall, the edge wall being inclined relative to the nominal surface (N) at an outward angle α1 of between 40° and 90° or a re-entrant angle α2 of between 90° and 100°, said portion of the edge wall extending to a depth P2 from the nominal surface, greater than or equal to the depth P1.
