Sub Base Types — Family-owned, 4.9★ rated, 15-year warranty
Building a sport court in Lilburn means thinking seriously about your sub-base—and honestly, that's where most installations either shine or fail. The clay-heavy soil around Gwinnett County doesn't drain like you'd hope, especially in those mature neighborhoods near Lilburn City Park and up toward Killian Hill. We've seen plenty of homeowners install turf over inadequate base layers, only to watch their court become a muddy mess after heavy rain or during Georgia's humid summers. The right foundation transforms a backyard basketball or tennis court into something that actually performs year-round. Your sub-base handles drainage, load distribution, and long-term stability—it's not glamorous, but it's absolutely critical in an area where the water table and clay composition can work against you. Whether you're working with a smaller lot in the city park neighborhoods or have more room to work with, the ground preparation determines whether your sport court lasts 10 years or turns into a nightmare in 3. We've been installing systems throughout the Atlanta metro for years, and Lilburn's specific soil profile demands respect and the right approach from day one.
Lilburn sits on Gwinnett clay, which is dense, compacts heavily, and doesn't naturally shed water the way sandy or loamy soils do. That clay is actually beneficial for base stability—it won't shift or settle unpredictably—but it means drainage planning isn't optional. If you're in one of the older suburban neighborhoods near Lilburn City Park or Killian Hill, your yard's topography and existing grading matter just as much as the soil type itself. Many of these mature properties have trees, varying sun exposure, and sometimes existing drainage patterns that were designed before anyone thought about a sport court. We typically recommend a compacted stone base (4–6 inches depending on your court type) with proper slope to divert water away from the play surface. Lilburn's humidity and occasional heavy downpours mean sub-base moisture management is genuinely important—your court sits directly on that base, so if water pools or percolates unevenly, your turf surface can develop soft spots or compress unevenly. Lot sizes in this area vary; some homes have plenty of room for a full court with good clearance, while others require creative placement or terracing. A proper sub-base assessment during the site visit catches these issues before installation begins.
Gwinnett clay is dense and doesn't drain naturally—it holds moisture, which can undermine your sport court over time. We compact it carefully and add engineered stone layers to create positive drainage away from the turf. Without this step in Lilburn, you risk surface pooling and premature wear. The clay does provide excellent load-bearing stability once it's prepped correctly, but skipping proper base construction here is asking for trouble.
Absolutely—we actually prefer slight slopes because they help with drainage. Steeper slopes need terracing or significant grading work, which adds cost and complexity. We assess your yard's natural grade during the consultation and design the sub-base to work with the terrain rather than fight it. Most Lilburn properties have workable slopes that support a great sport court with smart engineering.
Site prep typically takes 2–4 days depending on existing conditions, soil compaction, and drainage installation. Lilburn's clay sometimes requires extra compaction passes to achieve proper density. We don't rush this phase—a solid foundation in week one means your sport court performs for years. Once the base is locked in, turf installation moves quickly.
An engineered system with drainage layers, geotextile, and proper stone grading runs 30–50% more than a basic base. In Lilburn's clay environment, that investment protects your court. We've seen cheap bases fail within 3–4 years; engineered systems last 10+ with minimal issues. It's worth the upfront cost when you're building something meant to last.
