Basement Waterproofing Contractors in Burlington County, NJ
Burlington County lies wholly on New Jersey's Coastal Plain, and in townships such as Evesham the surface is sandy ground over the Kirkwood-Cohansey aquifer. Sand drains fast at the surface, but where the water table rises close to it in wet seasons, a basement can sit in groundwater for weeks.
What Evesham's soil survey shows
Evesham Township's environmental resource inventory, prepared with DVRPC, describes its most common soil, Lakehurst, as having a seasonal high water table 18 to 42 inches down, and rates Lakehurst fine sand as no problem for a house without a basement but very limited for one with a basement.
Atsion soils there are poorly drained, with the seasonal high water table 6 to 12 inches below the surface, and are rated very limited either way. Evesboro soils, by contrast, are excessively drained, with the water table deeper than 6 feet.
Inner and Outer Coastal Plain in Burlington County
The same Evesham report notes that the township straddles the Inner and Outer Coastal Plains, drained by branches of Pennsauken Creek and, mostly, the Southwest Branch of Rancocas Creek. It describes the Kirkwood-Cohansey aquifer beneath its sandy soils as one of the world's largest.
Burlington County's 2026 storms
An Inquirer analysis in September 2026 found Burlington County among the top 25 of more than 2,200 U.S. counties for flash flood warnings that year, alongside Camden and Gloucester. A sump that runs dry most of the year can be overwhelmed by a summer like that.
