- Anyone preparing questions for a concrete contractor
What a concrete base contributes
Concrete provides a rigid, continuous base for many hard-court surfaces. Its stiffness can suit certain surfaces and sites, but it also means that movement and cracking, if they occur, are handled differently from a more flexible base. These are engineering considerations a designer will weigh.
Concrete and asphalt are different tools, and neither is universally better. The right base depends on the surface, the site, the climate and professional judgement, so treat the choice as one to be reviewed by qualified professionals.
- Rigid, continuous base suited to certain surfaces and sites
- Reinforcement and joints are engineering matters, not DIY choices
- Behaves differently from asphalt; neither is universally better
- Relies on a properly prepared sub-base beneath it
Sub-base, joints and drainage
A concrete base relies on a prepared sub-base and on engineered details such as joints and falls for drainage. These are not planning details to settle yourself; they are designed by qualified professionals based on the site and loads. Your role at planning stage is to ensure they are accounted for.
Because base, sub-base and drainage interact, it helps to review them together. A qualified engineer can advise how the concrete should be detailed and drained for your ground and climate.
Surface, cracking and review
Surfaces over concrete depend on the base staying sound. Concrete can crack for various reasons, and any cracking should be reviewed by professionals before resurfacing, because the cause matters. Planning for periodic condition review keeps the court in good shape.
Rather than assume a concrete base never moves, plan for professional review so issues are diagnosed and addressed appropriately over the court's life.
Climate, movement and long-term review
Concrete responds to its environment, and how a base is detailed reflects the climate and conditions, which is why design is site-specific. Over the court's life, periodic review helps catch any movement or cracking before it affects play.
Plan for ongoing condition review rather than assuming the base is fixed forever. Qualified professionals diagnose any issues and advise whether repair or resurfacing is appropriate.
Concrete base planning checklist
- 1Have you discussed concrete versus other base options with a designer?
- 2Have you confirmed the sub-base and ground conditions are understood?
- 3Have you left reinforcement and joint details to qualified engineers?
- 4Have you reviewed how drainage falls are handled in the base?
- 5Have you matched the base approach to your chosen surface?
- 6Have you considered climate and exposure on your site?
- 7Have you planned for periodic condition review of the base?
- 8Have you confirmed official dimensions and standards with a supplier or federation?
Common mistakes to avoid
- Assuming concrete is always better or worse than asphalt
- Treating reinforcement or joints as choices to settle without an engineer
- Neglecting the sub-base the concrete relies on
- Choosing the base without reference to the surface on top
- Expecting concrete never to crack or move
- Skipping confirmation of official dimensions with the supplier
When to involve a professional
- A qualified engineer or designer should compare concrete and other base options for your site.
- Reinforcement, joints, sub-base and drainage are specialist engineering tasks for qualified professionals.
- Official court dimensions and standards vary and should be confirmed with the relevant federation, supplier or designer.
- Cracking and resurfacing decisions should be diagnosed and handled by qualified professionals.
Frequently asked questions
Questions readers ask about this topic
Is concrete better than asphalt for a court base?
Neither is universally better. The right base depends on the surface, the site, the climate and professional judgement. A qualified engineer or designer can compare the options for your specific project.
Do I need to decide reinforcement and joints myself?
No. Reinforcement, joints and falls are engineering decisions for qualified professionals based on the site and loads. Your role at planning stage is to ensure they are accounted for in the design.
Why might a concrete base crack?
Concrete can crack for several reasons, and the cause matters for any repair. Cracking should be reviewed by qualified professionals, and a condition assessment can guide whether resurfacing is appropriate.
Does a concrete base need drainage?
Yes. Falls and drainage are designed into the base so water clears rather than pools. The specifics vary by site and should be engineered and built by qualified professionals.
