Abstract
The invention relates to a surfacing for sports areas, more particularly tennis courts in which a bearing layer (2,2a) is applied to a surface (1) , fragments are then secured by means of the said bearing layer (2,2a) and arranged to leave voids and a top covering (4) of fine grains is applied. A process for preparing the surfacing may comprise a curable liquid resin that is cast as the bearing layer up to a thickness of about three to four millimeters on the surface and raked off. Fragments are about two-thirds embedded in the bearing layer and after curing a covering layer of fine grains is applied.
