Gravel French Drain Installation in Savannah GA. Done Right

French drains work by creating an easy path for water—gravel provides void space for water to enter, and perforated pipe carries it away. But the wrong gravel clogs, the wrong pipe collapses, and improper installation leads to failure. We use only commercial-grade washed gravel and heavy-duty perforated pipe. Every French drain we install is graded correctly, wrapped in filter fabric, and routed to proper outlets. The result is a French drain that actually works—and keeps working for years.

When You Need Gravel French Drain Installation

Choose a gravel French drain when you need to intercept groundwater or manage subsurface moisture. They work around foundations, in wet yards, and along slopes where water collects underground. If your crawl space gets wet from below (not surface water), a French drain can help. French drains are also used behind retaining walls to relieve hydrostatic pressure. They're the standard solution for moving water through soil.

Our Gravel French Drain Installation Process

We dig a trench sloped toward the outlet—typically 6-12 inches wide and 18-24 inches deep depending on conditions. Landscape fabric lines the trench to prevent soil infiltration. We add a base layer of washed drainage gravel, lay 4-inch perforated pipe with holes facing down, and fill around the pipe with more gravel. Fabric folds over the top before backfilling. The system drains to daylight, a drywell, or the stormwater system.
