摘要： The invention relates to a sport-technical layer for use in an artificial lawn system in particular intended for sports fields, which artificial lawn system is built up at least of a substrate to which artificial grass fibres are attached as well as the sport-technical layer extending under said substrate, which sport-technical layer comprises at least one damping sublayer made of a synthetic foam, which damping sublayer made of a synthetic foam is built up of an essentially rigid flat plate, which plate is provided with flatness-enhancing means. The invention further relates to an artificial lawn system provided with such a sport-technical layer. According to the invention, the sport-technical layer is to that end characterised in that said flatness-enhancing means comprise at least one first slot assembly of at least two closely spaced slots formed in a respective upper surface or bottom surface of the plate, which slots extend in a first direction of the plate. As a result, the sport-technical layer is constructionally guaranteed to be a flat layer not exhibiting any warped or overlapping portions. On the one hand this leads to improved functional characteristics of the artificial lawn system to be ultimately constructed, but in addition this prevents the unnecessary work and expenses involved in repairing a non-level sport-technical layer, which currently takes place with the artificial lawn system according to the prior art.
