Why Monmouth County basements get wet

Monmouth County is really two water problems in one. Along the ocean and the bay — Long Branch, Sea Bright, Neptune, and the Bayshore towns of Aberdeen and Keansburg — homes sit on sandy coastal soil with a high water table, and many were built as slab or crawl-space houses rather than full basements. When a nor’easter or the remnants of a storm push the groundwater up, water rises through the slab and floods low crawl spaces. The legacy of Superstorm Sandy is still visible here: raised homes, retrofitted crawl spaces, and sump systems that have to work harder than anywhere inland.

Move west toward Freehold, Manalapan, and Marlboro and the ground changes to heavy clay that holds water against foundation walls long after the rain stops, while the Swimming River and Navesink River lowlands keep the water table high. Put it together and Monmouth basements and crawl spaces get wet four main ways: hydrostatic pressure pushing groundwater up through the floor, foundation cracks in poured walls, seepage through block and crawl-space ground, and surface water from downspouts and grading. On the shore especially, a reliable pump with battery backup isn’t optional — it’s the difference between a dry home and a flooded one when the power goes out mid-storm.
