Abstract
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.
Claims13
A substrate with a floor structure thereon, the floor structure comprising a screed with a reinforcement system made of a 3D textile with a lower and an upper textile ply bonded to one another by one or more pile filaments, wherein the upper and the lower textile ply are embedded within the screed, and the lower textile ply is at the bottom of the screed and the upper textile ply is arranged in the upper half of the screed, wherein secured by tack or adhesion under the lower textile ply there is a sheet material,
- wherein the substrate with the floor structure thereon is obtained by a process, comprising the following steps:
- a) laying of the 3D textile with the sheet material secured under the lower textile ply of the 3D textile on top of the substrate or on a layer located above the substrate, and then
- b) filling of the 3D textile having been laid on the substrate or on the layer located above the substrate with a fresh screed material, and hardening to form the reinforced screed.
