ABSTRACT A surface covering for games arenas such as tennis courts comprising a slab formed of a plurality of regular polygon shaped regions, e.g. squares. The polygon shaped regions are delimited by ribs which depend from the upper load bearing surface of the slab and which abut the surface to be covered, and are delimited by grooves in the upper surface. Further ribs which depend from the upper surface are arranged to abut the surface to be covered, and radiate from the centre of each region, specifically along at least a part of each diagonal and each perpendicular bisector of each region when the regions are rectangular in shape. The grooves and ribs allow small expansions or contractions of regions due to temperature differentials to be absorbed by the individual regions and allow larger changes to take place substantially in the plane of the covering, thus avoiding ridges and cavities which occur with known coverings.
