1. An artificial turf system, comprising:
a used artificial turf, comprising a plurality of used artificial turf fibres and a used artificial turf backing layer configured to carry the plurality of used artificial turf fibres;
an unused artificial turf comprising a plurality of artificial turf fibres and an artificial turf backing layer, said artificial turf backing layer comprising a carrier structure configured to carry the plurality of artificial turf fibres; and
a geogrid positioned between the used artificial turf and the backing layer of the unused artificial turf, the geogrid including two or more grid layers, wherein one or more of the two or more grid layers each includes parallel strands having non-uniform cross sections as measured along lengths of the parallel stands, each of the two or more grid layers having a top surface, wherein the non-uniform cross sections as measured along the lengths of the parallel strands of each of the one or more of the two or more grid layers result in the top surface of each of the one or more of the two or more grid layers being tilted with respect to a horizontal plane.
