Abstract: An underlayment for a floor includes a dimpled substrate having a generally planar top side, an opposed bottom side, and a plurality of dimples formed therein. Each dimple is bounded by a dimple wall, and includes a dimple opening along the top side. A smoothing layer is bonded beneficial to the top side of the dimpled substrate and overlays and occludes the dimple openings.

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.

Abstract: A reinforced protective membrane comprises a water-resistant sheet and a reinforcing netting joined to the water-resistant sheet. The netting may be at least partially embedded in the water-resistant sheet. The reinforced protective membrane may also have a plurality of dimples formed therein. Each dimple may have a recess bounded by a dimple wall, and each dimple may have a dimple opening along a planar side of the water-resistant sheet that leads to the recess. The reinforcing netting may be joined to the water-resistant sheet such that the dimple opening is free from obstruction by the reinforcing netting.
