The invention relates to a method for producing a panel (1) for floor coverings and wall and ceiling linings, preferably for wet rooms, comprising the following steps: an upper longitudinal groove (6) is milled into a base panel, starting from the useful side (5) thereof; the longitudinal groove (6) is filled with an elastic, water-repellent plastic or sealing compound (9); and after the compound (9) has hardened, a lower longitudinal groove (11) is milled, starting from the rear side (10), the depth of which longitudinal groove extends as far as the compound (9) or into the compound, and an elastic expansion joint (12) is thus formed. A further method comprises the following steps: in the region close to the longitudinal sides (7), a respective edge groove (8) is milled into the base panel, starting from the useful side (5) thereof; the edge grooves (8) are filled with an elastic, water-repellent plastic or sealing compound (9); and after the compound (9) has hardened, a groove (13) and a tongue (14) for a tongue-and-groove joint are milled, with the respective outer lateral flank (15) of the compound (9) being milled in the process.

L'invention concerne un procédé pour fabriquer un panneau (1) pour revêtements de sol, de paroi et de plafond, de préférence pour des locaux humides, ce procédé comprenant les opérations suivantes : sur la face utile (5) du panneau de base est fraisée une gorge (6) longitudinale supérieure, qui est ensuite remplie d'une matière plastique ou d'étanchéité (9) élastique hydrofuge ; cette matière (9) ayant durci, au dos (10) du panneau est alors fraisée une gorge longitudinale inférieure (11) dont la profondeur s'étend jusqu'à ladite matière (9) ou y pénètre, pour former un joint élastique (12). La présente invention porte également sur un autre procédé consistant à fraiser une gorge de bordure (8) dans les zones proches des côtés longitudinaux (7) sur la face utile (5) du panneau de base, à remplir ces gorges de bordure (8) d'une matière plastique ou d'étanchéité (9) élastique hydrofuge et, cette matière (9) ayant durci, à fraiser une gorge (13) et une languette (14) pour créer un assemblage par rainure et languette, le flanc (15) latéral extérieur de la matière (9) étant entamé lors du fraisage.
