Courts for basketball, tennis and other sports need to be free of cracking. At the same time, they are large expanses of concrete and concrete tends to crack. The solution is to do a post tension concrete court. A well designed post tension sport court will resist cracking and provide a smooth level surface.
There is a misconception that doing a post tension court means that it has to be completely flat, but in many cases, like this one at the University of Denver, we have created a subtly sloped surface to promote drainage. Its also important to tie the surface to grade so there is run off space surrounding the court.
