For Newtown Square and Main Line homeowners dealing with basement moisture, the most effective long-term solution is exterior — intercepting groundwater before it reaches the foundation wall.
Target the Water Source
For Newtown Square and Main Line homeowners dealing with basement moisture, the most effective long-term solution is exterior: intercepting groundwater before it reaches the foundation wall. JHL Drainage Solutions installs exterior basement drainage systems throughout Delaware County from our Newtown Square office.
Older Delaware County properties — particularly Main Line homes built before modern drainage standards — frequently have foundations receiving water they were never designed to manage. Grade that has shifted toward the house, failed downspout systems, and absent perimeter drainage combine to create chronic moisture problems.
JHL's exterior approach targets the water source, not the symptom. A properly designed exterior system eliminates the hydrostatic pressure that causes seepage, efflorescence, and long-term structural damage.
