The water-bound mineral tennis court surface leveling beam is hollow. It is made of aluminum alloy with a steel reinforcement strip (A) in a D-section front portion. There is a square- section groove (B) behind the front portion for collecting excess material and moving it to fill depressions and potholes. The hollow rear portion is slightly tapered, with three parallel ridges (C).
