Abstract: The present invention relates to a substructure for an artificial lawn, comprising a top layer of artificial grass fibres and a number of underlying layers including a base layer, one or more intermediate layers and possibly other layers. The aforesaid substructure preferably comprises a water-permeable shock-absorbing layer, wherein said shock-absorbing layer is separated from said top layer of artificial grass fibres by one or more intermediate layers, wherein said one or more intermediate layers are selected from the group consisting of crushed stone, lava and sand, or a combination thereof.

Abstract: A substructure (1) for an artificial lawn, comprising a top layer (4) of artificial grass fibers (5) and a substratum (2), which substratum comprises a number of individual layers, including a base layer (2), an intermediate layer (7) positioned on top of said base layer an a sand layer (3) positioned on top of said intermediate layer, wherein said sand layer comprises at least two sublayers, wherein the first sublayer (11) comprises a sand fraction having a particle size which is larger than the particle size of the sand fraction of the second sublayer (13).
