GreenSet
GreenSet is a brand of acrylic hardcourt surface used in many professional tennis events run by the International Tennis Federation (ITF) and on the ATP and WTA tours. It is made of layers of acrylic resin and silica on top of an asphalt or concrete base, for permanent facilities, or on top of a wooden platform, for venues with occasional use. The company is based in Barcelona, Spain. GreenSet surfaces are homologated by the ITF Court Pace Rating categories, classified in the Medium-Slow, Medium and Medium-Fast. GreenSet has been in use since 1970, when it was first  introduced in Europe. Since then, over 60,000 tennis courts around the world have been coated with GreenSet. The surface is currently in use at the following tournaments: Many Davis Cup and Billie Jean King Cup ties are also held on GreenSet courts. Tennis at the 2016 Olympics in Rio was played on GreenSet Grand Prix Cushion courts. The Olympic Tennis Centre, with over 18,000 square metres, was completely surfaced in early 2016, months ahead of the event. GreenSet also supplied the BMX surfaces for the Olympic BMX Centre in Rio.
