Newark, NJ sits on clay and coastal plain soils and has a humid climate with about 44–48" of precipitation a year. The local water table is higher near the coast and in low-lying areas, with moderate winter freeze–thaw cycling, and full basements are common in the north. In practical terms, high rainfall, coastal storms and seasonal high water tables drive basement seepage — which is exactly why basement waterproofing is a common need here.
