About New Sport Court Construction
A new tennis, basketball, netball or multi-sport court is a specialist build, not a driveway with lines painted on it — get the base wrong and the surface will crack, pond water or play unevenly within a season or two, no matter how good the final coating looks on handover day. Tarworks Construction builds new sport courts for homeowners, schools, sports clubs, estates, complexes and municipal clients across Germiston, the East Rand and Johannesburg, using the same in-house crew, plant and base-first process we use across every trade we run. Excavation, layerworks, drainage, surfacing, line marking and fencing are all handled by one team, not handed between subcontractors who each answer for their own piece. We build each court to suit the sport, the site and how it will actually be used, on a free, written, on-site quote before anything starts, with no payment upfront for materials.
What's Included
- Excavated to design depth, sub-grade tested for soft spots
- Fill compacted in layers, each checked before the next
- Precise fall set into base to shed rainwater
- Perimeter drainage channel built in where needed
- Surface specified per sport: tennis, basketball, netball
- Regulation dimensions and line marking set out accurately
- Net posts, hoops, backboards and goals footed into base
- Perimeter fencing and LED lighting planned into the build
Our Process
- 1
Excavate and Build the Base
Every court starts the same way: excavation to design depth, removal of topsoil and unsuitable material, and a check of the sub-grade for soft spots, which matters most on sites with expansive Highveld clay. We build up compacted layers of selected fill, checking each layer before the next goes on, and set the fall into the base at this stage so the finished court sheds water correctly.

Surface to Suit the Sport
We specify the base and surface build-up around the sport the court is for — tennis, basketball, netball or a genuine multi-sport layout — rather than a one-size-fits-all coating. Tennis and basketball are typically finished with an acrylic hard-court coating over an asphalt or stabilised base, or a synthetic surface where that suits the site better; netball uses a hard-court or cushioned system, and multi-sport courts are planned around every sport they need to serve from the start.

Mark Lines and Fit Posts
Courts are marked out to regulation size and layout — including the key, three-point arc and free-throw line for basketball, or the three-third layout for netball — with net posts, hoops, backboards and goal posts footed into the base at the correct height and position before the final coating goes down.

Fence, Light and Hand Over
Perimeter fencing to keep the ball on the court, and LED lighting where the court needs to be usable after dark, are planned into the build from the design stage rather than added once the surface has cured, so the finished court is ready to play on at handover.

New Sport Court Construction FAQ
How much does it cost to build a new sport court?
There is no fixed rate, because the cost depends on which sport the court is for, its size, the condition and slope of the ground, how much excavation and base preparation it needs, the surface specified, and whether fencing or lighting are included. A half-court costs less to build than a full-size tennis or netball court, and a site that needs significant earthworks before it is level costs more than one that is already close to flat. We do not publish a rate card for that reason, but we do give a free, written, on-site quote before any work starts, on the same basis whether you are a homeowner, a school or a municipal client.
What is the best surface for a tennis, basketball or netball court?
It depends on the sport, the budget and how the court will be used. Tennis and netball courts are commonly finished with an acrylic hard-court coating over an asphalt or stabilised base, which gives consistent ball bounce and grip and copes well with outdoor weather. Basketball courts use a similar approach outdoors, with different specifications for an indoor installation. Synthetic surfaces are an option where a softer, more forgiving playing surface matters more than cost. We recommend the surface based on the sport and the site, not a single default option for every court.
How long does it take to build a new sport court?
It depends on the court's size and how much site preparation the ground needs before construction can start. A court on a site that is already reasonably level and well-drained builds faster than one that needs significant earthworks, drainage or retaining before the base can go in. Because we run excavation, base construction, surfacing and line marking as one job with our own crew, we are not waiting on hired plant or other trades between stages, which keeps the programme tighter than a build split across several subcontractors. We give a realistic timeframe as part of the written quote once we have seen the site.
Do I need council or municipal approval to build a sport court on my property?
It depends on the size of the court, where it sits on the property, and the municipality. Larger installations, courts near a boundary, and anything involving significant earthworks or drainage that ties into public infrastructure are more likely to need approval, while a smaller court well within a residential property's boundary often does not, but this varies by area. We will flag it honestly if your project looks like it needs sign-off before we start, rather than leaving you to find out later.
What base is used under a tennis or basketball court, asphalt or concrete?
Most outdoor tennis and basketball courts we build use a compacted layerworks base with an asphalt sub-base, finished with an acrylic hard-court coating, which handles South African weather and ground movement well and is more cost-effective than a full concrete build. Concrete is used in some cases where the ground or the client's requirements call for it. What matters more than which material is chosen is that the base is compacted properly in layers before surfacing, since a poorly compacted base will fail under either material.
