Quick answer
RDC Waterproofing’s New Jersey basement waterproofing services cover the whole problem: interior systems (basement waterproofing, French drains, sump pumps), foundation repair (crack injection, bowing & settling wall stabilization), exterior systems (excavation & membrane, yard drainage), and crawl space & air (encapsulation, humidity & mold control), plus egress windows and wet-basement repair. We inspect free, diagnose the source, and warranty the fix. Call (908) 569-1876.
Overview
Every service you need to keep a New Jersey home dry
Most waterproofing companies sell one system and fit every house to it. RDC works the other way around: we find where the water actually gets in — hydrostatic pressure, a foundation crack, the cove joint, or grading and downspouts — then match the right system to your home. Because water, foundation, and air problems feed each other, we handle all three under one accountable team, so you’re not chasing three subcontractors who point fingers.

The full RDC Waterproofing service line
All 11 waterproofing & foundation services
One accountable New Jersey team for water, foundation, and air.
Interior systems
Stop water from the inside
The most cost-effective, reliable way to keep the average New Jersey basement dry — installed cleanly and warrantied for life.
Basement Waterproofing
Engineered interior & exterior systems that stop water at the source — the flagship fix for a wet NJ basement.
French Drain & Interior Drainage
A perimeter drain under the slab collects water and routes it to the sump — dry for good.
Sump Pump & Battery Backup
Primary and battery-backup sump systems that keep pumping when a nor’easter takes out the power.
Foundation repair
Cracked, bowing & settling walls, stabilized
Water and pressure crack foundations — and a cracked foundation lets in more water. We seal the leak and, where the wall is moving, stabilize it permanently.
Foundation Crack Repair
Polyurethane and epoxy injection that seals leaking poured-concrete cracks for good.
Foundation Repair
Carbon-fiber straps, wall anchors, and piers for bowing, cracked, or settling foundation walls.
Egress Windows & Wells
Code-compliant egress windows and sealed window wells that stop a common basement leak point.
Exterior systems
Stop water before it reaches the wall
Sometimes the right fix is outside — excavation and membrane for a failing wall, or simply moving roof and surface water away from the foundation.
Exterior Waterproofing
Excavation down to the footing, a waterproof membrane, and a footing drain that stops water before it reaches the foundation — for failing walls or where interior drainage isn’t enough.
Yard & Exterior Drainage
Grading, downspout extensions, and catch basins that move roof and surface water away from the home — often the cheapest real fix.
Crawl space & air
Dry, sealed crawl spaces and healthy basement air
A damp crawl space or humid basement feeds mold, musty smells, and higher energy bills. We seal the space and control the moisture — after we correct the water source.
Crawl Space Encapsulation
Sealed vapor barrier, drainage, and dehumidification for a dry, usable, healthy crawl space.
Mold & Humidity Control
Energy-efficient dehumidifiers and mold prevention that keep the air in your basement healthy.
Wet & Flooded Basement Repair
We diagnose and permanently fix the real cause of a leaking, wet, or flooded basement.

How do I know which service my basement needs?
You don’t have to. Book a free inspection and RDC diagnoses the true source of the water, then recommends the one system (or combination) your home actually needs — not a sales script. If a $400 crack repair solves it, we won’t sell you a full system.

Our interior waterproofing systems carry a lifetime transferable dry-basement warranty, and every installation includes a written workmanship guarantee. You get the terms in writing before work begins.
Are your inspections and quotes really free?
Yes. We inspect inside and out, diagnose the source, and give you a written, fixed-price quote at no cost — 7 days a week, with no pressure.
