<p>The disclosure relates to a built-up playing court structure having a stable moisture content controlled surface layer. The playing court structure comprises a built-up court surface layer (12), a barrier surface (14) which is substantially impervious to moisture, a containment wall (16), a subsurface bed of aggregate (18), and pipes (20) for controlling the moisture content of the court surface. The surface preferably includes a layer of fine aggregate, such as granite, limestone, quartzite, and marble. This fine aggregate is disposed above an underlying subsurface layer of coarse aggregate, a mortar material, or mixture thereof. An adhesive elastomeric layer (32) may be disposed between the layers to permit free percolation of fluid between the layers.</p> |
