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 behaviour 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.

Abstract: The invention relates to an artificial turf with a backing and a large number of artificial grass blades which are fixed thereto, protrude substantially transversely thereof and are manufactured from plastic, and a fibrous, inherently damping material arranged between the artificial grass blades and connected to the backing or the blades. The fibrous, inherently damping material can herein be arranged in the form of a large number of blades which are connected to the backing and which likewise extend transversely of the backing, but less far than the artificial grass blades. The fibrous, inherently damping material can also take the form of a knit through which the artificial grass blades protrude and which can be formed integrally with the backing.

Abstract: The invention relates to a base layer for a combined synthetic and natural turf comprising a fabric of which at least a part of the weft and/or warp threads is manufactured from a biodegradable material and/or is wholly absent so that the fabric contains apertures, and synthetic turf fibers which are least partially cowoven with the fabric and of which one or both ends form synthetic grass blades. These ends only protrude from the fabric at those locations where the non-degradable warp and weft threads intersect. The base layer is used in combined synthetic and natural turfs comprising a foundation, optionally a first layer of growth substrate and a base layer according to the invention which is provided with a second layer of growth substrate in which grass plants grow. The invention further relates to a method for laying a combined turf using the base layer of the invention.
