Sports court construction and resurfacing requires a level of flatness and surface consistency that goes beyond standard pavement work. A tennis court surface with even one millimetre of ponding water becomes unplayable. A basketball court with undulation causes inconsistent ball bounce. We understand the standards that apply and build to them.
We construct and resurface asphalt base courts for tennis, basketball, netball, and multi-sport applications. The asphalt base provides a stable, durable foundation that, when constructed correctly, accepts the colour coat surface application required by the court sport. We work alongside surface coating contractors or can coordinate the full package.
Court resurfacing is a common requirement for community facilities, school grounds and strata complexes on the Central Coast. Where the existing base is still structurally sound, resurfacing the asphalt base layer and applying a new colour coat extends the court life at a fraction of full reconstruction cost. Schools and clubs off the Coast get the same offer. We have already rebuilt a court at Warners Bay on Lake Macquarie, and we will quote one at Newcastle, Maitland or Hornsby.
Flatness Standards
Courts constructed to tight flatness tolerances. Ponding water tested and eliminated before handover.
Asphalt Base
Durable hot-mix asphalt base prepared to accept colour coat or direct play surfaces.
Multi-sport Layouts
Basketball, netball, tennis and multi-sport court layouts in one asphalt base surface.
Court Resurfacing
Existing court base assessed and resurfaced where structurally sound, at lower cost than reconstruction.
Drainage Grading
Courts graded to shed water to perimeter drainage without affecting play surface flatness.
Anatomy of a sports court surface
The colour coat is a few millimetres of acrylic. Everything it does, good or bad, comes from the asphalt underneath. Here is the full build-up, coats exaggerated so you can see them.
- Compacted base and asphalt pavement 3mm under 3m
Crushed rock compacted to a true plane, then dense hot-mix asphalt finished to no more than 3mm variation under a 3m straightedge. This is the layer we test for ponding before anyone paints it.
- Smoothness decides playability
The coats follow the asphalt exactly. A dip you can barely see holds a millimetre of water, and one millimetre of ponding makes a tennis court unplayable. The court still needs fall to drain, just never more than 1:100, in a single true plane.
- Acrylic coating system
A filler and resurfacer coat tightens the asphalt texture, then two colour coats build the playing surface. Applied by specialist coating contractors over a base we hand over tested and signed off.
- Line marking goes on last
Lines are painted over the finished colour coats, never under them. If everything below is flat and true, the lines stay crisp and the bounce stays honest.
Courts do not fail at the paint. They fail at the asphalt under it, and the asphalt is the part we build.

The Process
Every job follows the same standard. No steps skipped, no quality shortcuts.
Sub-base Assessment
Existing or proposed sub-base assessed for suitability, drainage and level adequacy.
Base Construction
Compacted sub-base and asphalt base course constructed to specified tolerances and drainage grade.
Flatness Testing
Finished asphalt base tested for flatness and ponding before surface handover.
Surface Handover
Base handed over to colour coat contractor, or direct line marking applied for asphalt-finish courts.
Frequently Asked
Questions specific to Sports Courts on the Central Coast.
Ask Us Anything →Getting other quotes too? Smart. Take our questions sheet (PDF).
What flatness standard do you build sports courts to?
We build to the Australian Tennis Court Builders Association specification and equivalent standards for other court sports. The standard requires no more than three millimetres variation under a three-metre straight edge on the finished playing surface.
Do you supply the colour coat surface, or just the asphalt base?
We specialise in the asphalt base construction. We work alongside specialist colour coat contractors, or can coordinate the full package through our network. The asphalt base needs to be correct for the colour coat to perform as intended.
Can a cracked or uneven existing court be resurfaced?
It depends on the nature of the problem. Surface cracking and minor unevenness can often be addressed with overlay and preparation work before a new colour coat. Significant base settlement or drainage failure requires more substantial intervention. We assess the existing court during quoting.
- Asphalt base not tested for ponding before the colour coat contractor arrives
- Flatness tolerance not checked, leaving inconsistent ball bounce on day one
- Drainage grade calculated wrong, leaving a low point at the centre of court
- Sub-base not trimmed to the tolerances sports court specs demand
- Base contractor and colour coat contractor never coordinated on levels
- Court delivered, used once, puddles reported at the back of the baseline
Ponding water. Inconsistent bounce. Colour coat peels because the base was wrong.
Glenn and his team were terrific. Such a difficult job made to look easy.
