Abstract (en)
A method of constructing a playing surface for sports such as soccer, cricket and tennis comprises the steps of laying at least one flexible water-permeable envelope (4) containing an unbonded base material (5) rising sand, on a drained or water-permeable surface (1), and placing a sheet (9) of a resilient material on to the envelope. In a preferred embodiment, a second sheet (20) of resilient material having different bounce characteristics from the first is placed on the first sheet, and an artificial turf material (10) is laid on top.
