The invention relates to a support and/or drainage plate made of a foil-like plastic material, for use with a plate-lined floor structure or a wall so as to create a space between the ground and the surface lining to be applied onto the foil-like plate. The structure of the plate is such that cavities are created by means of, on the one side, projections extending substantially in one direction and, on the other side, raised areas at the same level between which chambers are embodied for receiving a hardening contact medium, such as mortar or adhesive, which forms a contact layer with the surface lining to be applied. According to the invention the structure consists of projections (N1, N2) or (S1, S2) which extend in at least two directions and intersect. The resulting chambers (M1) are delimited in their circumference by the projections (S1, S2), which are open towards the other side of the plate.

1. In combination with a base of a floor, ceiling or wall structure and with an adhesive contact layer and a surface facing adhered on said adhesive contact layer, a support plate comprising:a foil made of a synthetic sheet material, having spaced apart inner and outer sides, and formed with a plurality of raised web regions disposed at said outer side and extending in longitudinal and transverse directions of said outer side so as to intersect one another and a plurality of base web regions disposed at said inner side offset from and between said raised web regions so as to be spaced from one another by said raised web regions, said raised and base web regions being interconnected together by connection web regions extending between said inner and outer sides of said foil so as to define inwardly open grooves and outwardly open chambers therebetween in a pattern in which said inwardly open grooves intersect one another and are located behind said raised web regions of said foil and said outwardly open chambers are spaced from one another and located in front of said base web regions of said film so as to receive in said outwardly open chambers portions of said adhesive contact layer protruding within said outwardly open chambers to said base web regions of said foil, said raised web regions including edge portions which overhang said outwardly open chambers so as to define undercut portions thereof that retain said portions of said adhesive contact layer therein; and a webbing attached to said inner side of said foil and to said base such that said foil is thereby attached to said base via said webbing and said foil also is attached to said surface facing via said adhesive contact layer so as to permit installation of said surface facing via said foil to said base of floor, ceiling or wall structure while at the same time neither said base nor said adhesive contact layer are not attached to one another because said foil is disposed therebetween and thereby provides a decoupling of differing stresses between said surface facing and said base.
