Concrete Basketball Court Installer in Shelby, NC

A concrete basketball court is a heavier build than most homeowners expect. The slab has to shrug off a bouncing ball landing repeatedly on the same footprint, absorb the point-load of a heavy-duty in-ground hoop base, and stay flat for a decade under North Carolina sun and freeze-thaw cycles. Courts that fail early almost always trace back to a slab that was too thin, a hoop footing that was not detailed as a separate pour, or a base that never got compacted properly. The regulation NBA half court is 50 feet by 47 feet and a full court is 50 by 94, but real backyard courts sit at three common sizes: a 30×30 hoop pad, a 30×50 half court with painted key, and a 50×60 half court with proper three-point arc — each with its own slab spec and hoop-mount detail.

Local Concrete Contractor scopes basketball court pours across North Carolina starting with a site walk covering pad orientation (rim under a north-south sight line to keep sun out of shooters' eyes when it matters), grade and drainage, subgrade type, hoop location, tree canopy interference, and the surfacing plan — acrylic modular tile, poured acrylic coating, or a broom-finish concrete court all sit on the same slab spec but change the finish handoff. We deliver a written spec covering pad dimensions, slope, base build, thickness, reinforcement, joint pattern, hoop-footing detail, and finish before dirt moves. No deposit up front, no vague scope on the invoice.

Basketball Court Slab Sizes and Specs We Pour

Court size is a mix of what you want to play and what actually fits in the yard. Getting the slab spec right for the size and use pattern makes the difference between a court that plays like a real court and one that spider-cracks by year three.

• Hoop pad — 30×30 (900 SF), room for a hoop plus a solid free-throw shooting area and enough space to move for one-on-one
• Backyard half court — 30×50 (1,500 SF), enough for a painted key, three-point line, and adult-scale play
• Regulation-style half court — 50×47 (2,350 SF), full NBA half-court dimensions with three-point arc, key, and full baseline run
• Small full court — 50×74 (3,700 SF), high-school-style shortened full court
• Regulation full court — 50×94 (4,700 SF), NBA/college full dimensions, typically HOA or club scope
• Driveway-conversion court — existing driveway extended or repoured to hit court dimensions
• Multi-sport pad — basketball plus pickleball line overlay on 30×60 or 34×64

Every slab we pour hits the same core spec: 5-inch minimum thickness (6 inches on courts with in-ground hoop bases embedded through the slab), 4,000 psi mix, #4 rebar on 16-inch centers, sawcut control joints on a 12×12 grid, 1% slope in one direction for drainage (side-to-side is standard, never toward the hoop-side sideline), broom or steel-trowel-then-broom finish depending on the surfacing plan, and cast-in-place hoop footings poured before or with the slab pour.

Base Prep, Drainage, and Why Most Courts Crack Early

The single biggest reason a basketball court fails early is the base underneath the slab. A pad poured directly on unimproved subgrade or on 2 inches of loose stone will telegraph settlement cracks within a year, and the point-load of a heavy in-ground hoop base makes the failure worse — the slab sinks unevenly under the hoop before it does anywhere else.

Our base spec: strip 8-10 inches of topsoil, compact the subgrade to 95% Proctor, install and grade 4-6 inches of #57 washed stone as a drainage layer, compact again in 2-inch lifts, then pour on top. Under the hoop location specifically we go deeper on the stone base (6-8 inches) because a full-size in-ground hoop with a 4×4×48-inch anchor footing puts serious localized load on that spot every time the rim gets used.

Drainage direction matters. The slab must fall 1% (about 1 inch of drop over 8 feet) in one direction so water sheds off the pad. Sloping toward the hoop creates a puddle right where you shoot free throws every time it rains, and a dead-flat court holds water at the low spots and shortens surface life. Perimeter drainage — a French drain along the low side, or at minimum a graded swale directing water 10 feet clear of the pad — keeps the base dry season after season.
