Protect your court from heat, rain and seasonal changes
Outdoor sports courts in South Africa face tough weather conditions throughout the year. Heat, UV exposure, heavy rain and sudden temperature swings slowly wear down the surface. If a court is not built or maintained properly, these forces eventually cause structural damage.
This guide explains how weather affects tennis, netball and basketball courts — and how to keep your facility in excellent condition for many years.
Main weather conditions that damage courts
1. Heat and strong UV sunlight
Asphalt expands during high temperatures
Acrylic colours fade when UV protection weakens
Thin surfaces soften in extreme heat
Tyre or scuff marks appear where players turn sharply
UV exposure is the main reason court colours fade over time.
2. Heavy rain and storms
Water settles in low areas
Rain seeps into cracks
The base softens
Cracks widen, leading to dips or potholes
Water damage almost always begins where slope and drainage were poorly designed.
3. Sudden temperature changes
Hot days and cool nights
Surface expands and contracts
Fine hairline cracks begin to form
These small cracks grow rapidly during the rainy season.
Signs of weather related damage
Slippery areas after rain
Puddles lasting more than ten minutes
Fading colour or dull texture
Cracks across the court
Uneven ball bounce
Moss or algae forming at the edges
Small warning signs usually indicate deeper base issues if ignored.
How to protect your court from weather damage
1. Acrylic coating maintenance
Recoat every four to six years to
✔ Renew surface grip
✔ Restore bright colour
✔ Protect asphalt from UV and heat
2. Crack sealing
Seal early to prevent water from reaching the base.
This simple step avoids major structural repairs later.
3. Drainage improvement
Fix low areas so water drains off the court properly.
Good drainage prevents soft spots, dips and future cracking.
4. Regular inspections
After storms, check for
Soft or spongy spots
New cracks
Slippery areas
Early intervention saves money and extends the lifespan of the court.
Why weather affects some courts more than others
Courts deteriorate faster when
✘ The base layer is too thin
✘ The slope or drainage was not designed correctly
✘ Cheap paint was used instead of acrylic coating
✘ Trees are too close and roots cause movement
✘ Heavy vehicles are driven over the surface
Strong construction protects the court against these risks.
Lifespan of a well maintained court
With proper coating and drainage, a sports court can last fifteen to twenty five years before major resurfacing is needed.
Without maintenance, severe cracking and structural failures can appear within three to five years.
Preventative care saves thousands in long term repair and rebuilding costs.
