Every year your clay court material goes through a migration pattern due to the weather. A standard clay court sits with 40 tonnes of material creating a complete playing surface depth of 1 inch. Over 12 months a standard court will experience 4-5 tonnes of material migrating to the lowest area of the court and eventually washing off. This is completely normal. In order for the court to maintain its quality in playing condition a court needs to be redressed and new material applied. Whether you have a residential clay court or a country club, we can take care of you.
