A substrate for sports and recreation fields, a backing for an artificial lawn provided with such a substrate, an artificial lawn provided with such a substrate and a composition for such a substrate

摘要

The invention relates to a substrate for sports and recreation fields, in particular artificial grass sports fields that contain granular infill material, which comprises at least one component that can leach out upon contact with water and which further comprises a binder material for binding the leached-out component. The invention also relates to a backing and to an artificial lawn provided with such a substrate. The object of the invention is to provide an improved substrate for a sports/recreation field as described in the introduction, and in order to accomplish that object the binder material is provided on or in the substrate. This makes it possible in the case of saturation to simply collect and carry off the substrate with the binder material and the leached-out component that is bound thereto or held therein.
