Hard court surfaces

Hard surfaces, especially unenriched, so gravel and crushed stone, made for the purposes of games, they have very similar external properties to ground surfaces. They outperform them with easier intake and discharge of excess rainwater. The surface layer of these pavements should not be made of sharp aggregates, such as crushed stone and wedges, causing cuts, in falls. Therefore, natural aggregates are better for this purpose, as gravel and sands sorted. Dusting materials should also be avoided, like clay sands and aggregates of easily wearable stones. Granulated aggregates made of clinker bricks are used to build the top layer of tennis courts, which give the characteristic color.

Concrete paving slabs can be used for some amusement games. The boards should be of good quality with a flat and smooth surface and carefully arranged in one plane without protruding or lowering edges.
