Comprehensive Runoff & Grading Solutions for Lowcountry Properties

Standing surface water is more than an inconvenience—it actively destroys turfgrass, compromises landscape designs, and creates breeding grounds for pests. In areas like Summerville and Charleston, land is frequently graded flat with little natural relief, causing massive volumes of rainwater to pool in low spots rather than running off into municipal storm lines.

At Palmetto Infrastructure Group, we look at your entire parcel topographically. We engineer custom surface drainage systems that catch storm runoff the moment it hits your property and channel it to designated municipal termination points or retention areas.

Our Core Surface Drainage Capabilities

No two pieces of land drain exactly the same way. We diagnose the exact hydraulic bottlenecks on your property and apply the proper mechanical fix:

  • Yard Grading & Swales: Re-contouring the soil to create a natural, grass-lined channel (swale) that guides water away from patios, driveways, and foundations via gravity alone.
  • Commercial-Grade Catch Basins: Installing heavy-duty surface grates in chronic low spots to immediately swallow pooling downpours and redirect them into hidden underground pipelines.
  • Downspout Redirection: Tying your gutter system directly into buried, smooth PVC lines so roof runoff is transported cleanly off your property without eroding your perimeter beds.
  • Channel Drains: Installing narrow, flush-mounted trench drains across concrete driveways, garage entry thresholds, and pool decks to stop sheet-flow water tracking toward doors.

Why Standard Landscaping Fixes Fail

Many local property owners try to fix pooling water by simply dumping topsoil or sand into the low spots. This does not solve the problem—it merely shifts the water to another area of your lawn or pushes it against your home's crawl space wall. True water mitigation requires correct elevation shots, a verified slope calculation, and heavy-duty, smooth-walled conduits that won't collapse under soil weight over time.
