hose cracks in your tennis court are getting completely out of hand. So what’s the best course of action?Quite simply, it depends on the reasons for the cracking, and the type of cracking.
According to Tennis Courts: A Construction and Maintenance Manual, published by the USTA and the American Sports Builders Association,
Cracking of asphalt is caused, at least in part, by the natural tendency of asphalt to shrink as it weathers and ages. In addition, asphalt loses its flexibility over time, making it more brittle.
Premature or extensive cracking may be caused by poor asphalt mix design, by poor site conditions including expansive soils or excessive organic matter in soils resulting in sub-base movement, or by poor construction including inadequate drainage.
Because asphalt is a material that shrinks and becomes more brittle as it ages, almost all courts made of asphalt will suffer from some type of cracking — either major or minor — at one time or another. Additionally, a court may show more than one type of cracking. A tennis court contractor is the best judge of the type of crack, the seriousness, and the cause. Once those factors have been identified, a treatment can be recommended.
Treatments can be simple — requiring only an afternoon’s work — or they may be extremely complex — involving total reconstruction — or they may fall anywhere in between. A qualified court contractor can help you find the solution to your problem.
Crack repair is — as the term suggests — simply addressing the problem at hand by filling the crack. Contractors find that some cracks, such as those that are simply the result of freeze-thaw cycles and not of any serious underlying condition, can be treated with a crack-filling compound. (A very deep crack may require a full-depth repair, and the contractor should evaluate such a crack to see if it indicates an underlying problem with the court as a whole).
