Surfaces covered in green clay, also referred to as “American clay” are by far the favourite surface for most tennis players. This clay is manufactured from a stone call “metabasalt”, which is broken down into fine angled particles giving it hardness once it has been rolled (compacted) and watered. This surface is particularly sensitive to effects, gives excellent ball rebounds, while absorbing shocks, reducing the effect of impact on body joints. It enables the player to move rapidly because of it’s skid texture. Clay surfaces are an excellent choice for our Quebec climate and the ground movements caused by freezing and unfreezing because any depressions that form can easily be repaired. The Family Circle Cup has always been played on clay courts. Recent studies made by the FFT have qualified clay surfaces as “the comfort surface”.
