Floating floor system

A composite structure for a floating floor system comprising 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 and wherein the layer of formwork is a half closed folded honeycomb structure or a relaxed honeycomb structure, said honeycomb structure being produced from a continuous film, which can be composed of a thermoplastic polymer or thermoplastic elastomeric polymer, by plastic deformation perpendicular to the plane of the film such that three-dimensional structures and connection areas are formed, so that half-hexagonal cell walls and small connections areas are formed, and subsequently, the three-dimensional-structures are folded towards each other, so that the half hexagonal cell walls are at an angle α to each other or adjoin one another in the form of a honeycomb cell, the structure being water impermeable and the void volumes on one side of the layer of formwork not being connected to void volumes on the other side of the layer of formwork.
