Abstract: A decoupling assembly for positioning between an underlying surface and a flooring material, the decoupling assembly including a decoupling membrane having a base panel having opposing upper and lower surfaces and a plurality of projections extending from the lower surface for contacting an underlying surface and supporting the base panel above the underlying surface. Each projection includes a bottom surface. The assembly further includes a plurality of adhesive fasteners, each adhesive fastener having an inner surface fixed to the bottom surface of a respective one of the plurality of projections, and an adhesive outer surface opposite the inner surface. The assembly further includes a plurality of release members, each release member covering the outer surface of one respective adhesive fastener, each release member being removable to expose the outer surface of the respective adhesive fastener for adhering the decoupling membrane to the underlying surface.
