Abstract:
The invention relates to a method for laying a playable surface (11; 21; 41; 51), comprising the steps of forming a relatively hard substrate (12; 22; 42; 52), arranging on the relatively hard substrate (12; 22; 42; 52) at least one layer of a resilient and/or damping material (13; 23; 43; 53), and arranging a top layer (14; 24; 44; 54) on the layer of resilient and/or damping material (13; 23; 43; 53). In one embodiment air chambers (27) are formed in the layer of resilient and/or damping material (23) during arranging thereof by including granules (31) having dimensions amounting to more than half the thickness of the layer (23). In another embodiment air chambers (17) are formed in the layer of resilient and/or damping material (13) by removing material therefrom at different locations after the arranging thereof. The invention further relates to a playable surface that is laid by applying this method.
