Local conditions
Why Gloucester County basements get wet
Gloucester County runs from the Delaware River inland, and its soil is a patchwork of sand and clay that keeps basements damp in different ways. Along the river — West Deptford, Woodbury, and the Mantua and Woodbury Creek lowlands — the water table sits high and older homes on block foundations seep through the wall after heavy rain. The creeks that thread through Mantua, Deptford, and Woodbury keep the surrounding ground saturated well after a storm passes.
In the post-war and newer suburbs — Washington Township, Glassboro, Monroe — the soil holds more clay in spots, trapping water against foundation walls and driving it up through the slab under hydrostatic pressure. Across Gloucester County, basements take on water four main ways: hydrostatic pressure through the floor, foundation cracks in poured walls, seepage through porous block, and surface water from downspouts and grading. The fix has to match the cause — which is exactly what RDC’s free inspection is for.
