Hard Courts (Concrete)
Concrete tennis courts are a viable option when space or site considerations make it difficult of impossible to build an asphalt tennis court. Examples include roof decks, parking decks and private homes without access for paving equipment. Concrete tennis courts have the same playing characteristics as asphalt tennis courts. Court owners can also customize the color, speed and cushioning of the court to suit their individual preferences. Many private homeowners utilize their concrete tennis courts for other activities, including basketball.
Standard Concrete Court
Concrete tennis courts consist of four inches of concrete with a medium broom finish poured over a properly graded sub-base. It is important that a vapor barrier, usually a 6 mil plastic liner, is installed over the sub-base before the concrete is poured. This barrier will prevent moisture from being drawn into the concrete and getting trapped between the concrete and the acrylic coating system.
Once the concrete has cured, a concrete primer coat is applied to ensure that the acrylic resurfacing product will adhere to the concrete surface. The court is then flooded to reveal any low areas in the concrete surface. A patch binder mix is then applied to fill in the low areas. Two coats of acrylic resurfacing product are next applied to repair any minor imperfections in the concrete surface. Two coats of acrylic court paint are then applied, followed by the playing lines. The pace of ball bounce can be somewhat controlled by adding more or less sand to the acrylic resurfacing product and acrylic court paint. Most new courts will require a four coat color system (two coats of resurfacing product, two coats of color product). You as the court owner can choose from a variety of different colors to match your tastes. The blue and green combination used at the U.S. Open in New York is increasingly popular with our clients.

Cushioned Concrete Court
One of the disadvantages of a standard concrete tennis court is that they can be hard on the body and joints. Several rubberized cushioning systems have been developed to ease the pain of playing on a concrete court. The cushioning system is applied between the acrylic resurfacing product and the acrylic court paint. Once the acrylic resurfacing product is applied (see above), 5 to 9 coats of rubberized cushioning surface are applied to the court. This generally includes 2 to 3 coats of heavy grade rubber granules followed by 3 to 6 coats of fine grade rubber granules. Cushioned concrete tennis courts are significantly more expensive than standard concrete tennis courts.
The most popular cushioning system in the world is DecoTurf. DecoTurf is used at the USTA National Tennis Center in New York City, home of the U.S. Open. Fast-Dry Courts, Inc. is very experienced with the DecoTurf product. In fact, we recently completed a DecoTurf resurfacing project for Serena and Venus Williams at their home in Florida .
