Abstract
The invention relates to a method for laying a playable surface such as a playing field, comprising the steps of forming a hard substrate, arranging on the hard substrate a layer of resilient and/or damping material, and arranging a top layer on the resilient and/or damping layer, wherein during or after arranging of the hard substrate and/or the resilient and/or damping layer air chambers are formed therein. The behavior of the playing field becomes more natural due to these air chambers, and excessive resilience and energy restitution are avoided. The air chambers can be formed for instance by creating recesses in the relevant layer from the top, or by removing material from the layer at different locations after arranging thereof, for instance by melting or biological decomposition of inclusions. The invention also relates to a playing field obtain by application of this method.
