About Court Pace Classification

Notes:
All surfaces may be porous or non-porous, with the exception of "Clay" and "Grass", which are always porous.
Acrylic Normally forms only the uppermost few millimetres of a court.
Artificial Clay, Artificial Grass "Appearance" relates only to the form of the surface material and not other characteristics (e.g. colour).
Asphalt, Concrete Used only when the material itself forms the playing surface. When used as a base for other surfaces (e.g. acrylic), reference will be made only to the playing surface.
Clay This term denotes a type of surface that is constructed from naturally-derived materials, and includes an unbound fine gritty material as the uppermost (playing) layer, e.g. fast-dry. The integrity of the surface shall not be reliant on the addition of a carpet or membrane layer to the structure.
