New Jersey’s Basement Waterproofing Experts
RDC Restoration keeps New Jersey basements permanently dry
RDC Restoration is a New Jersey basement waterproofing company serving homeowners, landlords, and property managers across Union, Middlesex, Somerset, Essex, and neighboring counties. Instead of mopping up after every rainstorm, RDC Restoration finds why your basement leaks — hydrostatic pressure, foundation cracks, failed drainage, or a dead sump pump — and installs the right interior or exterior system to stop water for good.
A damp or flooding basement is more than a nuisance. Standing water and chronic humidity feed mold, rot framing, ruin stored belongings, and can undermine the foundation your entire house sits on. Because RDC Restoration also handles water damage restoration and mold remediation, we see firsthand what an unwaterproofed basement eventually costs. Waterproofing is simply the permanent fix for the emergencies we get called to clean up.
RDC Restoration operates from two New Jersey hubs — Berkeley Heights in Union County and Piscataway in Middlesex County — so a crew can inspect your basement quickly and follow water-management and mold-control best practices set by the IICRC and NORMI. From the first inspection to the final drainage test, you get one accountable New Jersey team — not a rotating cast of subcontractors.
Every way water gets into your basement
What RDC Restoration installs
No wet basement has a single cause, so RDC Restoration builds a complete system — drainage, pumping, sealing, and moisture control — matched to your New Jersey home.
Interior Perimeter Drainage
A drain channel set below the slab along the footing collects water and routes it to the sump — the backbone of most New Jersey basement waterproofing systems.
Sump Pumps & Battery Backup
High-capacity sump pumps with a sealed basin and battery backup keep discharging water even during the storm-driven power outages that flood NJ basements.
Foundation Crack Repair
RDC Restoration seals poured-wall and block cracks with structural injection to stop the seepage and efflorescence that hydrostatic pressure forces through.
Exterior Waterproofing Membranes
Where the fix belongs outside, we excavate the foundation and apply a waterproof membrane so groundwater is blocked before it ever reaches the wall.
French Drains & Grading
Exterior French drains and corrected grading move surface and subsurface water away from the foundation, easing the pressure that pushes water inside.
Vapor Barriers & Dehumidification
Wall and floor vapor barriers plus dedicated dehumidification control the humidity that causes musty odors and mold long after the standing water is gone.
The RDC Restoration process
How RDC Restoration waterproofs your basement
Inspect & Diagnose
RDC Restoration inspects the foundation, checks grading and hydrostatic pressure, and pinpoints exactly where and why water enters your basement.
Repair & Seal
We inject and seal foundation cracks, address efflorescence, and prep the walls and slab so drainage and barriers perform as designed.
Install Drainage & Sump
Interior perimeter drainage, a high-capacity sump pump with battery backup, and any needed French drains or exterior membrane go in.
Verify & Protect
We water-test the system, add vapor barriers and dehumidification, and confirm your New Jersey basement stays dry through the next storm.

Water After Rain
Puddles, seepage at the wall-floor joint, or a sump that runs constantly after every New Jersey storm.
Efflorescence
Chalky white mineral staining on foundation walls — a telltale sign water is passing through the masonry.
Foundation Cracks
Vertical, horizontal, or stair-step cracks that let water and hydrostatic pressure push inside.
Musty Odor & Mold
A persistent damp smell or visible mold means humidity and moisture the space can’t shed on its own.
Peeling & Rust
Bubbling paint, damp drywall, or rust on appliances and support posts from chronic dampness.
Failing Sump Pump
An old, undersized, or backup-less sump pump that can’t keep up when the water table rises.

Basement waterproofing questions
How much does basement waterproofing cost in New Jersey?
Cost depends on the size of your basement, whether the fix is interior or exterior, and how many feet of drainage, crack repair, or sump work is involved. RDC Restoration provides a free on-site inspection and a clear written estimate before any work begins. Request a free estimate or call (908) 253-9000.
How long does basement waterproofing take?
Most interior perimeter drainage and sump pump systems are completed by RDC Restoration in one to three days, while exterior excavation and membrane projects can take longer. After a quick inspection, RDC Restoration gives you an exact timeline. Call (908) 253-9000 to schedule.
Should I choose interior or exterior basement waterproofing?
Interior perimeter drainage with a sump pump manages water that has already entered and is the most common New Jersey solution, while exterior membranes stop groundwater before it reaches the wall. RDC Restoration inspects your foundation and recommends whichever approach — or combination — actually fixes your problem. Get a free assessment today.
What causes a wet basement in New Jersey?
Common causes include hydrostatic pressure from a high water table, foundation cracks, poor grading and gutters, and failed or undersized sump pumps. RDC Restoration diagnoses the exact cause rather than guessing, so the waterproofing actually holds. Call (908) 253-9000 to have your basement evaluated.
Does basement waterproofing come with a warranty?
Yes. RDC Restoration stands behind its basement waterproofing systems with a warranty, and because we are a local New Jersey company with two hubs, we are here if you ever need us again. Ask about warranty details when you request your estimate.
