A flooring system with internal cavities includes a shaped intermediate flooringlayer which is positioned between an upper flooring layer and a lower flooring layer and includes pot-shaped depressions and flat, intervening portions surrounding the depressions. The depressions are filled with a sound dampening filler material. This preventsaccumulation of the cementous top layer material in the region of the depressions which significantly reduces the drying time of the cementous top layer and reliably prevents internal tension in the top layer. Filling the depressions with sound absorbing material significantly reduces the transmission of sound or footsteps from the top layer to the bottom layer.

Cette invention concerne un système de revêtement de sol à cavités internes qui comprend une couche intermédiaire placée entre une couche supérieure et une couche inférieure et comportant des creux en forme de cuvette séparés par des parties plates. Les creux étant remplis d'un matériau insonorisant, la chape de ciment ne s'y accumule pas, sèche beaucoup plus rapidement et demeure exempte de contraintes internes. En remplissant les creux de matériau insonorisant, on réduit sensiblement la transmission du bruit ambiant et de choc de la couche supérieure à la couche inférieure.
