Charlotte’s clay-heavy soil does not compact or drain the way gravel does, so the builder will excavate the court footprint and replace the native soil with a compacted gravel sub-base before any concrete is poured. That base layer is what keeps the slab from shifting as the ground moves through wet and dry cycles across the Carolinas’ seasons.
The concrete slab is poured at 4 to 6 inches thick with rebar reinforcement throughout. Control joints are cut at planned intervals so any expansion or contraction happens at the joint rather than as a random crack across the playing surface. Slab thickness and joint placement are set based on the court size and expected load.
Once the slab has cured fully, the builder installs the playing surface, either a painted acrylic coating or interlocking modular tiles, and sets up the basketball hoop with a ground sleeve anchor. A half-court layout works for most residential spaces and keeps the footprint manageable without sacrificing a regulation key and three-point arc.

From first enquiry to finished court in three steps
How much does it cost to install a basketball court in my backyard?
Most backyard basketball court installations come in at $15,000-$35,000, depending on court size, surface type, and base work required. Site conditions like slope, drainage, and soil type also move the number. An on-site evaluation produces an itemised written estimate so you know exactly what you are paying for before any work starts.
What affects the cost of a basketball court installation?
Court size, surface material, and base preparation are the three biggest cost drivers. A full concrete pour costs more than modular tile over an existing slab. Sloped or poorly draining yards need more grading work, which adds to the base prep line. Fencing, lighting, and custom line striping each add to the total.
Do you handle site prep and base work, or is that separate?
Site prep and base work are included in the project scope, not treated as a separate contract. Every job starts with an on-site evaluation covering drainage and ground conditions. The written estimate then itemises base preparation, surfacing, and any fencing or lighting, so nothing is hidden or handed off to another contractor.
How much space do I need for a half court or full court?
An NBA full court is 94 by 50 feet, but a recreational full court typically runs 84 by 50 feet. A standard half court is 47 by 50 feet. Add at least 3 feet of buffer on each side for safe play. Smaller lots can still fit a 30 by 30 foot shooting area if a regulation half court is not possible.
Can a basketball court be built on grass?
No. Grass cannot support a stable playing surface. The ground beneath it shifts with moisture and foot traffic, which causes cracking and uneven bounce. The grass and topsoil must be removed, the subgrade graded and compacted, and a proper base installed before any surface goes down.
Should I use concrete, modular tile, or another surface for my court?
Concrete is the most durable long-term base and gives the truest ball bounce, but it requires proper thickness and curing. Modular polypropylene tile installs faster, drains through the surface itself, and is easier to repair section by section. Asphalt is a lower-cost alternative but softens in high heat and needs resurfacing sooner. The right choice depends on your budget, soil, and how often the court will be used.
How thick does the concrete slab need to be for a basketball court?
A residential basketball court slab is typically 4 inches thick with a compacted aggregate base beneath it. Heavier-use or commercial courts often call for 5 to 6 inches. The subgrade must be properly graded and compacted first, otherwise even a correctly poured slab will settle and crack over time.
Will my court drain well and hold up in wet weather?
Good drainage starts at the base prep stage. The court is graded with a slight slope, typically 1 percent, so water runs off rather than pooling. Modular tile surfaces drain through the joints. Concrete and acrylic surfaces rely on that slope. An on-site drainage evaluation before installation identifies any problem areas specific to your yard.
