Who this guide is for
- Owners who have noticed cracking on a court
- Facility managers documenting surface issues
- Club committees deciding how to respond to cracks
- Anyone preparing to brief a repair specialist
Documenting what you see
Good documentation helps a specialist diagnose accurately. Noting where cracks appear, their pattern, and whether they are changing over time gives useful context. Photographs and a simple record of when issues were first noticed turn vague concern into actionable information.
Documentation is something owners can do well; diagnosis is where specialist judgment takes over.
- Record where cracks appear and their pattern
- Note whether cracks are changing over time
- Photograph issues for context
- Record when problems were first noticed
Understanding that cracks have causes
Cracks can arise from base or sub-base movement, drainage problems, material aging or other factors. Because the cause shapes the right response, surface-only repair may not hold if the underlying issue remains. Recognizing this prevents repeated, ineffective fixes.
Identifying the actual cause requires specialist assessment and varies by court and site.
- Recognize cracks as possible symptoms
- Understand that causes vary and need diagnosis
- Avoid assuming a surface-only fix will hold
- Note any related drainage or movement signs
Why repair is specialist work
Crack repair involves judgment about cause, method and materials that varies by surface and situation. Inappropriate repair can mask problems or shorten surface life. This is firmly specialist territory, and the assessment and repair should be reviewed and performed by qualified professionals.
Avoid sources that promise a single universal repair method, as suitability depends on the specifics.
Planning your next steps
Once cracks are documented, the practical next step is engaging a qualified specialist to assess cause and advise on repair. Keeping your records to hand and noting any related drainage or movement signs helps that conversation be productive.
Official court dimensions and standards should be confirmed with the relevant federation, supplier or designer where repairs affect markings or play.

Frequently asked questions
Questions readers ask about this topic
Can I just fill a crack myself?
Crack repair requires judgment about cause, method and materials that varies by surface. Inappropriate repair can mask problems. Diagnosis and repair should be reviewed and performed by qualified professionals.
Why do cracks come back after repair?
Often because the underlying cause, such as base movement or drainage, was not addressed. Cracks can be symptoms, so a surface-only fix may not hold if the cause remains.
What should I document before calling a specialist?
Record where cracks appear, their pattern, whether they are changing, and when first noticed, with photographs. This context helps a specialist diagnose the cause more accurately.
How urgent is a crack?
It depends on the cause and whether it affects safety or play. We do not assess urgency remotely. Documenting and engaging a qualified specialist for assessment is the appropriate step.
