Patent ID: 8684277

Claim:
A multi-layer build-up system for floor coverings, comprising: a plate-shaped component having accommodation spaces for pipelines of a floor heating system; an uncoupling mat disposed on an upper surface of the plate-shaped component, said uncoupling mat comprising an uncoupling layer and at least one anchoring layer; said uncoupling layer being formed of a nonwoven textile and connected with a surface of the plate shaped component by a flexible adhesive; a tile adhesive that is plastic during processing and hardened afterwards; said anchoring layer being disposed on top of the uncoupling layer, said anchoring layer comprising accommodation spaces for receiving plastic tile adhesive; and a reinforcement layer disposed on top of the anchoring layer, at least in sections, said reinforcement layer comprising openings for receiving plastic tile adhesive; wherein hardened tile adhesive, the reinforcement layer, and the at least one anchoring layer form a unitary composite body that is resistant to bending after the tile adhesive in a plastic state has been applied through the openings in the reinforcement layer and accommodation spaces of the anchoring layers and the tile adhesive has hardened, so that a floor covering applied on top of the build-up system is unaffected by changes in a substrate and/or the plate-shaped component that occur underneath the floor covering and guides heat undisturbed from the pipelines to the floor covering.
