Among the most typical problems seen with concrete tennis courts and asphalt is surface cracking. There’s a lot of causes for pavement cracks from improper construction to oxidation and ground movement. Once pavement begins to crack, it develops into a maintenance issue. Permanent crack repair hasn’t been perfected yet, but there a few great strategies and products to keep them and slow down the degradation.
Why should you seal the cracks?
When cracks appear in the court surface, water can drain into the crack and loosen the base materials. This may accelerate the progress of the crack or even result in more substantial problems. Also, excessive water that penetrates the surface cracking can freeze and expand to create more cracking.
Hard tennis court surfaces are acrylic based. When filling the cracks, be sure to always use an acrylic crack sealant that’s appropriate for the surfacing materials. Asphalt based, also called “rubberized” crack fillers, should not be used with acrylic tennis court coatings. While asphalt based crack fillers may be good at sealing the crack, acrylic coatings won’t adhere to them for very long. The beautiful court surface will have black lines all over the location where the color coatings release.
If your court is located in an area that has expansive soils or freezing temperatures, you might want to look for an elastomeric tennis court crack filler. These products are flexible and can stretch with the contracting and expanding cracks or even joints. Several manufacturers also make acrylic crack fillers in common colors or neutral, tintable formulas. By doing this you don’t have to resurface all areas of the court to hide the crack repair if it is not needed.

Some minor tennis court repairs can be performed by do-it-yourselfers. Nonetheless, extensive damage or cracks with heaving should be repaired by a professional sport surfacing contractor. If you would like assistance locating a qualified applicator near you, contact a manufacturer of sport surfaces for contractor referrals.
