Sub Base Types — Family-owned, 4.9★ rated, 15-year warranty
Sandy Springs North homeowners know the drill: that North Fulton clay soil drains like a sponge in reverse, and your natural grass putting green turns into a soggy mess half the year. We've been installing synthetic putting greens across the Dunwoody border and Abernathy corridor for years, and honestly, it's one of the smartest upgrades we see people make. The difference between a backyard that stays lush and playable year-round versus one that's patchy and waterlogged comes down to getting your sub-base right. That's where most installers cut corners, and that's where we don't. Whether you're near Morgan Falls or closer to North Springs MARTA, the installation process is the same: we assess your existing grade, handle drainage the way it needs to be handled in this clay-heavy area, and get you a putting surface that actually performs. No more excuses about the weather. No more watching your investment wash away after a heavy rain.
Sandy Springs North sits on some of the trickiest soil in the metro area—that North Fulton clay holds water like it's got a personal vendetta. Before we lay down any synthetic turf, we're looking at your lot's natural slope and how water moves across it. Most yards in the Abernathy corridor and near Dunwoody are suburban-sized, which gives us room to work with proper drainage solutions that bigger-lot installers sometimes skip. We typically excavate 4 to 6 inches, depending on what's underneath, and build a sub-base that actually lets water percolate instead of pooling. The clay means you can't just spread crushed stone and call it a day—we're using engineered drainage rock and sometimes adding a perforated underdrain if your grade is particularly flat. Sun exposure varies wildly depending on tree canopy coverage in these neighborhoods, so we'll walk your property and recommend the right infill and blade height to handle both full-sun and dappled-shade zones. Your HOA landscape guidelines matter too, and we factor those in from the start.
Clay is dense and compacted, so water doesn't drain naturally—it sits. A standard shallow sub-base fails fast here. We excavate deeper and use engineered drainage rock to create a base that actually moves water away from your turf. Without this step, your putting surface becomes a swamp every spring and after heavy rain, which is exactly what we see when homeowners try DIY installs in this area.
Most residential jobs in the Abernathy corridor and Dunwoody-border areas take 2 to 3 days, depending on how much excavation and base prep we need. If your yard has heavy clay or poor existing grade, we might need an extra day. We schedule you, show up, and get it done without dragging the project out. We're 28 minutes from your neighborhood, so we're local enough to respond quickly if adjustments are needed.
Yes, but only if the sub-base is built right. We remove the clay down to proper depth, install gravel and drainage rock in the correct sequence, and often add a perforated underdrain system if your lot is flat. The result is a surface that drains as well as a natural green in California—even though you're sitting on clay that would normally trap water.
Many neighborhoods in this area have landscape guidelines, and we're familiar with what the common restrictions are. We'll review your covenants before we start and make sure your putting green meets those standards. Most HOAs approve them once they understand the maintenance benefits and year-round appearance.
