ABSTRACT:
A flooring, preferentially designed to be used for laying running tracks, includes a treading layer constituted by an elastomer mass and a supporting layer also constituted by an elastomer mass. The supporting layer has, on the side opposite to the treading layer, an array of cavities delimited by ribbings constituting a mesh of uniform ribbings. The cavities are cavities having an elongated shape in the direction of running on the flooring. The cavities occupy a volume equal to at least 28%, and preferentially at least 30%, of the volume of the supporting layer.
