Local conditions
Why Somerset County basements get wet
Somerset County knows river flooding better than almost any place in New Jersey. The Raritan River and its Millstone and North Branch tributaries cut right through the middle of the county, and the low ground around Bound Brook, Manville, and Raritan Borough has been hit by catastrophic flooding — Tropical Storm Floyd in 1999 and Hurricane Ida in 2021 both put those downtowns underwater. Even in ordinary storms the water table there rises fast and pushes groundwater up through basement floors. Basement waterproofing in Somerset County starts with understanding how close your home sits to that river-driven water.
Away from the river, the county’s heavy clay soils cause their own problems, holding water against foundation walls in Bridgewater, Hillsborough, Franklin, and Montgomery long after the rain stops and cracking poured walls as the ground swells and shrinks. Put it together and Somerset County basements take on water four main ways: hydrostatic pressure pushing groundwater up through the floor, foundation cracks in poured walls, seepage through porous block, and surface water from downspouts and grading that slope toward the house. The fix has to match the cause — which is exactly what RDC’s free inspection is for.
What we install
The right waterproofing system for your Somerset County home
One accountable local team, matched to your foundation and your water problem.
Interior French drains
Perimeter drainage under the slab that collects water and routes it to a sump — the reliable fix for clay-soil and Raritan-valley homes across Somerset County.
Sump pumps & battery backup
A dependable pump with a battery backup that keeps working through Raritan flooding events when the power goes out.
Foundation crack repair
Polyurethane and epoxy injection that seals leaking poured-concrete cracks permanently — common where clay soils shift foundations.
Exterior waterproofing
Excavation, membrane, and footing drains for failing walls or where water must be stopped outside.
Yard & exterior drainage
Grading, downspout extensions, and catch basins that move roof and surface water away from the foundation.
Humidity & mold control
Dehumidification and vapor barriers to finish the job and keep Somerset County basement air healthy.

Somerset County waterproofing questions
Frequently asked questions
Do you provide free basement inspections in Somerset County?
Yes. RDC offers free, no-pressure inspections throughout Somerset County, 7 days a week. We inspect inside and out, diagnose where the water is coming from, and give you a written, fixed-price quote at no cost. Call (908) 569-1876.
How much does basement waterproofing cost in Somerset County?
It depends on the cause. A leaking crack sealed by injection is a few hundred dollars; a full interior French drain with a sump and battery backup for a typical Somerset County home runs several thousand. You get a fixed, itemized quote after the free inspection, and we recommend only what you need.
My Bound Brook or Manville home has flooded before — can waterproofing help?
Yes. The Raritan valley towns of Bound Brook and Manville have seen major flooding from storms like Floyd and Ida, and even routine rain raises the water table and pushes water up through the slab. An interior French drain with a strong primary pump and battery backup manages the water that reaches your basement and keeps the floor dry between events.
Which Somerset County towns do you serve?
All of them — including Franklin, Bridgewater, Hillsborough, Basking Ridge, Somerville, Montgomery, Warren, Bound Brook, Raritan, and Manville, dispatched from our nearby Piscataway hub.
Is the warranty transferable if I sell my Somerset County home?
Yes. Our interior waterproofing systems carry a lifetime transferable dry-basement warranty that stays with the home — a real selling point at closing. See our guarantees.
