CLAY (AND SHALE)
A clay court is constructed using natural stone that is crushed to different levels. The finest level –a
powder – is used for the uppermost layer (top dressing) and loosely bound together with water.
The most common forms are red clay (terre battue) made from brick and grey clay (basalt),
although the coarser-grained shale and soil-like anthill are also used.
Performance
Clay courts are normally among the slowest court surfaces, often producing the longer rallies, and
are responsive to spin.
Use
Outdoor clay courts are not normally used in areas with high rainfall, as they take a relatively long
time to dry, hence reducing the time available for play. Clay courts cannot be used during frosty
weather.
Advantages
The mobile top dressing allows controlled sliding, which can make it more comfortable to play.
Repairs are generally inexpensive.
Materials are readily available in many places.
Disadvantages
The surface takes time to dry following rain.
Daily maintenance is required to keep a clay court in top condition. Lines require regular painting,
sweeping and levelling.
