  • Patent number: 5429453
    Abstract: An improved surface covering for use in tennis courts or other fields on which games are played and which require a hard surface. The surface covering includes layers of materials applied on an old existing covering which is inferior for one or more reasons. The new covering includes a drain rock layer beneath a flexible fabric panel which is beneath a new base rock layer. A layer of asphalt is applied to the base rock layer, following which a thin layer, such as of bitumen or the like, can be applied to the top of the asphalt layer. The new covering will "float" on top of the old covering to allow the old covering to expand or contract due to ground movement while also eliminating moisture problems.
