French Drain Installation
Perforated pipe and gravel systems that intercept and redirect subsurface groundwater away from your foundation and yard.
French drains are the most effective solution for subsurface water problems in Chester County and Delaware County. JHL Drainage Solutions designs and installs French drain systems that intercept groundwater and redirect it to a safe discharge point — a daylight outlet, dry well, or storm drainage connection — before it can cause foundation damage, basement moisture, or yard saturation.
Our installations consist of a gravel-filled trench with perforated pipe engineered to use natural grade for gravity-fed drainage. We size pipe diameter, trench depth, and discharge routing for each site — there’s no standard formula for Chester County’s variable terrain and clay-heavy soils.
JHL Drainage Solutions has resolved French drain failures and new installations throughout West Chester, Newtown Square, and all of Chester County and Delaware County. We provide a free site assessment and written estimate before any work begins. Call the office nearest you.
