Sub Base Types — Family-owned, 4.9★ rated, 15-year warranty
Building a sport court in Snellville means thinking bigger than just aesthetics. Your yard—whether it's in the Snellville Towne Center area or out toward South Gwinnett—needs a foundation that handles Georgia's weather and supports serious play. That's where sub-base preparation becomes the real conversation. Most Snellville homeowners don't realize that clay-heavy soil, which dominates Gwinnett County, shifts seasonally and can wreak havoc on an unprepared court surface. We've installed dozens of courts across this area, and the ones that last—the ones where kids are still shooting hoops or playing volleyball five years later—those all start with a proper base layer. We're talking about engineered crushed stone, compaction specs, and drainage routes that account for how water moves through established residential lots here. The difference between a court that's smooth and fast versus one that settles unevenly or pools water after rain? It's almost entirely sub-base work. That's not exciting talk, but it's the work that matters. Let's walk through what your Snellville lot actually needs.
Gwinnett County clay is both a blessing and a problem for sport courts. It's stable when dry, but it holds moisture longer than sandy soils, and it expands and contracts with seasonal changes. Most Snellville properties—especially in established neighborhoods around Briscoe Park and The Towne Green—sit on lots that have been graded and compacted over decades. That sounds solid, but it often means old fill material, inconsistent compaction, and unpredictable drainage patterns underneath. Before we lay any turf, we excavate and assess what's actually there. Typically, sport courts in this area need 4 to 6 inches of crushed stone base—sometimes more if the existing soil is particularly clay-heavy or if your lot drains toward a low spot. Sun exposure varies enough in Snellville that we consider tree coverage and afternoon heat when recommending infill materials. HOA communities here tend to have landscape guidelines, so we coordinate on material choices and edge treatments before work begins. The clay also means we're extra careful about compaction procedures—we're not just dumping stone and spreading it; we're using proper equipment to achieve the density that prevents settling over time. Your court's longevity in Snellville comes down to respecting what's underneath.
Gwinnett County's clay soil behaves differently than sandy or loamy soils. It swells when wet and shrinks when dry, which creates movement under the turf. If your sub-base isn't compacted and stable, that movement translates to uneven court surfaces, divots, and standing water. Proper sub-base engineering locks everything in place and drains water away from your court.
Most residential courts here need 4 to 6 inches of engineered crushed stone, depending on existing soil conditions and drainage. We test your lot first—if clay is dense or drainage is poor, we may go deeper. Compaction is just as important as depth. We specify compaction methods and verify density to ensure your court stays level.
We slope the sub-base slightly—typically 1 to 2 percent—to move water away from the court and toward natural drainage paths or designated runoff areas. In clay-heavy properties, we sometimes install perforated drain tile under the stone base. The goal is zero standing water after rain, which keeps the court playable and prevents damage.
Some Snellville communities have landscape or construction guidelines. We work with your HOA before breaking ground—coordinating on colors, edging, and any setback requirements. Most HOAs in the area approve sport courts because they're residential amenities, but checking first saves headaches and delays.
