A profiled web for arrangement between the underside of floor tiles and an upper surface of a support plate. The profiled web is based on a rigid plastic film formed to have a parallel series of successive channels, each of the channels being defined by first and second edge portions and a trough portion therebetween. The series of channels are open alternately to the upper surface of the support plate as a first group of channels and to the underside of the floor tiles when in an installed position as a second group of channels. First trough portions of the channels open to the support plate are parallel, and form an upper surface of the web; second trough portions of the channels open to the tiles are parallel and form a lower surface of the web. The web is provided with a plurality of through-openings which produce a liquid- and gas-permeable connection between successive channels. A liquid- and gas-permeable textile mesh is adhesively laminated to the upper surface of the web and extends across successive channels in the form of a plane. In an alternate embodiment, a supporting profile strip is located in transverse orientation to the channels, at the longitudinal ends of the channels.
