Basement Waterproofing Contractors in Camden County, NJ
Camden County is one of the South Jersey counties where a basement's trouble is often clay, not sand. NJGS mapping of the Camden and Philadelphia quadrangles describes glauconite clay in the Merchantville Formation, up to 50 feet thick, and clay in the Woodbury Formation.
Four boroughs above the radon line
NJDEP's 2015 report placed Lawnside (about 42% of 69 tested homes at or above 4 pCi/L), Runnemede (31%), Magnolia (30%) and Somerdale (26%) in Tier 1. Cherry Hill, with 10,319 homes tested, was Tier 2 at about 19%.
Those Camden County boroughs are a reason to put an airtight lid on any new sump and to retest after crack work.
Cloudbursts in 2026
On July 6, 2026, nearly four inches of rain fell on the City of Camden in about an hour, according to city officials, flooding basements in several neighborhoods. On August 3, residents of a Pennsauken street reported at least six flooded basements, which they believed came from sewer backup.
By September, an Inquirer analysis counted Camden County among the top 25 of over 2,200 counties nationally for flash flood warnings in 2026.
Sewers and sump discharge
Camden County's municipalities collect sewage that the Camden County Municipal Utilities Authority then treats, and the CCMUA requires its own permit before a sewer connection is made. A waterproofing job in Camden County should send sump water outdoors, not into that system.
Housing age
More than 30% of Camden County homes date from 1960 to 1979, according to DVRPC's county housing profile built on 2022 Census survey data, which puts many basements well past the age when coatings and drains start to fail.
