One of the most common complaints about tennis courts in Gauteng is cracking. Cracks not only look unsightly but can also affect play and safety. Understanding why cracking happens and how to prevent it is key to long-lasting courts.
At William Gift Civil, we specialize in durable tennis court construction and resurfacing designed to resist Gauteng’s unique climate and ground conditions.


Why Do Tennis Courts Crack?
•Poor Sub-base Preparation: If the ground beneath isn’t compacted correctly, it settles unevenly, causing surface cracks.
•Ground Movement: Gauteng soils often expand and contract due to rain and heat cycles, putting stress on rigid surfaces.
•Inadequate Drainage: Water pooling weakens the base and can cause freeze-thaw damage in cooler months.
•Wrong Surface Choice: Concrete courts without flexibility crack more easily than asphalt.
•Improper Jointing: Expansion joints help surfaces move safely; missing or badly placed joints cause random cracks.


How to Prevent Cracking
• Conduct professional soil testing and site analysis before construction.
• Use a well-compacted G5 or G6 sub-base to stabilize the ground.
• Design effective drainage systems to quickly remove water.
• Choose the right surface material (asphalt is more flexible).
• Install correctly spaced expansion joints to absorb stress.
Repairing Existing Cracks
• For minor cracks, use specialized sealants and fillers.
• For larger cracks or structural issues, resurfacing or partial rebuilding may be necessary.
• Regular maintenance prolongs court life and prevents cracks from worsening.
