Abstract: The membrane is for use with a planar surface and includes a generally planar member and a plurality of resilient tabs. The generally planar member, in use, is disposed in parallel relation to and adjacent the planar surface and, at least in use, defines a plurality of troughs, the troughs being interconnected to define a planar network of troughs that is disposed parallel to the surface, each trough presenting away from the surface in use and terminating in a common plane that is parallel to and spaced from the surface. The tabs are provided for each of one or more of the troughs, the tab lying in the common plane and spanning at least in part across said each trough.

Abstract: The present invention provides an improved uncoupling membrane for use between a top coat of mortar in which a tile layer is set and a base coat of mortar applied to a substrate surface. The membrane being of the type including a dimpled plastic layer, the dimples defining, on one side of the membrane, a number of depressions into which the top coat extends in use and, on the other side of the membrane, a number of protuberances. The improvement may include a polymeric coating overlaying the plastic layer and to which the top coat of mortar adheres in use.
