Basement Exterior Drainage
Exterior perimeter drainage systems that intercept groundwater before it reaches your basement walls.
Basement moisture and water intrusion are most effectively addressed from the exterior — intercepting groundwater before it reaches the foundation wall. JHL Drainage Solutions installs exterior perimeter drainage systems that protect your basement from the outside, addressing the root cause rather than managing symptoms inside.
We install French drain systems at the base of foundation walls, integrated with proper downspout routing and grade correction, to create a complete exterior moisture management system. This approach is more durable than interior drainage systems and prevents long-term foundation damage.
Exterior basement drainage is a significant investment, but it solves the problem where it originates — outside the foundation. JHL Drainage Solutions provides thorough site assessments and detailed estimates for West Chester, Newtown Square, and all of Chester County and Delaware County.

Common Questions
Generally yes. Exterior drainage intercepts water before it contacts the foundation wall, preventing both moisture intrusion and long-term structural damage. Interior systems manage water that has already entered.
We excavate along the foundation perimeter, install a perforated pipe French drain at footing level, backfill with clean gravel, and route discharge to a daylight outlet or dry well. Grade correction and downspout rerouting are often included.
Excavation near a foundation may require a permit depending on the municipality. We review permit requirements as part of every site assessment and handle the process where required.
