A composite structure for a floating floor system including at least one layer of force muting material and a layer of formwork, wherein the layer of formwork is located on the at least one layer of force muting material wherein the layer of formwork is a half closed folded honeycomb structure or a relaxed honeycomb structure.

A decoupling sheet (1) having a carrier plate (2) and a plurality of nubs (4) protruding from the carrier plate plane (3), wherein adjacent nubs (4) are arranged transversely to the lengthwise direction (5) and in the lengthwise direction (5) of the carrier plate (2). It is provided according to the invention that immediately adjacent nubs (4) transversely to the lengthwise direction (5) and in the lengthwise direction (5) of the carrier plate (2) have a nub base (10) of triaxial shape, especially with at least three leg sides (6b).

A floor underlayment includes a fiber pad and a vapor barrier layer. The fiber pad includes reinforcement fibers and thermoplastic binder fibers binding the reinforcement fibers together. The vapor barrier layer has a bottom surface attached to the fiber pad, a top surface opposite of the bottom surface, and a matrix of holes extending through the top and bottom surfaces thereof. The holes are configured to allow moisture to flow through the holes in a downward direction from the top surface of the vapor barrier layer to the bottom surface of the vapor barrier layer while inhibiting water flow through the holes in an upward direction opposite of the downward direction.

A covering for underlays of flooring includes: a membrane with a base from which studs extend which protrude upward with respect to the laying plane, a draining layer which is joined in an upper region to the membrane at the top of the studs, and a layer for anchoring to the underlay of the flooring, joined in a lower region to the membrane at least at the base.

An uncoupling mat (1) includes a flexible plastic layer (2) made of a film-like plastic with structuring that defines indentations (6) provided with undercuts (5) on the first side (4) and cavities (8) positioned between the indentations (6) on the opposite second side (7). A fleece or fabric (3) is securely connected to the second side (7) and covers the cavities (8). The plastic layer (2) is provided with a plurality of weakening zones (12) which extend continuously between opposing side edges of the plastic layer (2).

A decoupling sheet (1) having a carrier plate (2) and a plurality of nubs (4) protruding from the carrier plate plane (3), wherein adjacent nubs (4) are arranged transversely to the lengthwise direction (5) and in the lengthwise direction (5) of the carrier plate (2). It is provided according to the invention that immediately adjacent nubs (4) transversely to the lengthwise direction (5) and in the lengthwise direction (5) of the carrier plate (2) have a nub base (10) of triaxial shape, especially with at least three leg sides (6b).

A two part floor covering useful for entranceway is provided having a mat overlaying a base. A fastening system incorporating a mushroom-type fastener is provided, whereby the mat can be laid on the base and positioned as desired, without the fastening system engaging. When the mat is aligned with the base, downward pressure on the mat engages the fastening system and restricts the mat from slipping laterally or lifting vertically. Alignment and deployment of the textile component with the base component in an efficient manner is also described herein.

A floor construction on a subsurface has a screed with a reinforcement made of a 3D textile with a lower and an upper textile ply which are connected together by one or more pile threads, wherein the lower textile ply is arranged in the lower half of the screed and the upper textile ply is arranged in the upper half of the screed, wherein an insulation layer is preferably furthermore arranged between the subsurface and the screed. The reinforced screed of the floor construction allows thin screed layers with good load-bearing capacity. Good footfall sound insulation can be achieved with the floor construction containing an insulation layer.

The moisture vapor reduction system of the present invention comprises of as a first component the special mineral adhesive, being a hydraulic mineral adhesive, which comprises filling materials selected from the group of mineral fillers and/or plastic fillers and further comprises a binding material composition selected from the group consisting of Portland cement clinker, calcium-sulfo-aluminate and mixtures thereof, combined with an excess of a sulfate providing agent and further comprises as a second component a cover, e.g. a sheet or foil, made out of a waterproof and/or vapor-retarding material.
