Abstract:
1. Method for laying a playable surface, in particular a playing field, comprising the steps of: forming a relatively hard substrate with a horizontal, fiat top surface, arranging on the relatively hard substrate at least one layer of a resilient and/or damping material, and arranging a top layer on the at least one layer of resilient and/or damping material, wherein the at least one layer of resilient and/or damping material extends under the entire surface of the top layer, and wherein during or after arranging of the layer of resilient and/or damping material, permanent air chambers are formed therein, the permanent air chambers being embedded only in the at least one layer of resilient and/or damping material, the permanent air chambers not extending below the top surface of the relatively hard substrate, wherein the permanent air chambers are formed in the at least one layer of resilient and/or damping material by creating recesses therein from the top side after it is arranged, wherein the recesses are created by moving a machine provided with protruding parts over the at least one layer of resilient and/or damping material.
