From minor seepage to full basement flooding, JCB Waterproofing and Construction provides engineered solutions that protect your foundation and your investment.
Here is what sets our basement waterproofing team apart from the rest.
Interior perimeter drains installed by our crew are fully sealed, backfilled with clean aggregate, and protected by a lifetime clog-free warranty that transfers to new owners.
We treat every crack, joint, and tie rod penetration as a potential failure point and address each one individually rather than painting over the problem.
Every technician on our crew holds current certification in basement waterproofing systems and participates in ongoing training as products and methods evolve.
We deliver detailed written quotes that break down every material and labor cost -- no surprise line items appear on your final invoice that were not on the original estimate.
Hydrostatic pressure is the invisible force behind nearly every basement water problem homeowners face in Montclair, NJ. When soil around your foundation becomes saturated -- whether from heavy rain, snowmelt, or a high water table -- it exerts outward and downward pressure against concrete walls and floor slabs that can exceed hundreds of pounds per square foot. Over time, this pressure finds the smallest weakness: a tie rod hole, a cold joint between wall and footing, a shrinkage crack in poured concrete, or a deteriorated mortar joint in block construction. Once water finds its path, that path widens with every wet season until a trickle becomes a flood.
A well-installed interior drain tile system is designed around the specific hydrology of your property. Basements in Montclair that sit in naturally high water table zones require larger-diameter pipe and higher-capacity pumps than basements that only collect surface runoff during heavy storms. Our assessment process measures both the volume and the frequency of water intrusion to right-size every component -- from the pipe diameter to the pump horsepower and battery backup capacity.
In poured concrete walls, the most common seepage points are cold joints, tie rod holes, and form tie locations. These are concentrated, well-defined penetrations that respond well to polyurethane or epoxy injection -- a process of drilling small ports along the crack or joint, installing surface-mounted injection ports, and pumping low-viscosity resin under pressure until it fills the void completely. The cured resin is permanently flexible or rigid depending on the product chosen, creating a watertight seal that moves slightly with seasonal concrete expansion without reopening.
Floor cracks are a separate category of water entry that many homeowners underestimate. A hairline crack in a poured concrete floor can transmit significant water when the slab sits on soil with a high water table. Injection of these cracks follows the same principle as wall cracks: drill ports, install fittings, and pump polyurethane resin that expands to fill the void and bond with the surrounding concrete. In situations where the slab has heaved or settled, crack injection is supplemented with undercutting and re-pouring a portion of the slab to restore a flat, properly sealed floor surface.
A complete basement waterproofing system also requires a reliable, properly maintained sump pump installation. We specify sump pits that are large enough to accommodate both a primary pump and a battery backup pump with sufficient separation that the backup does not interfere with the primary float. Discharge lines are routed to daylight at a point that ensures water flows away from the house and cannot recirculate back to the foundation. Battery backup systems are sized to handle a sustained pumping load during a power outage -- not just a brief test cycle -- because the storm events that knock out power are precisely the events that generate the highest water volume in your basement.
Six core services covering every source of basement moisture in Montclair homes.
Perimeter drain channels installed at footing level route water from wall-floor joints to a central sump basin, eliminating standing water completely.
Poured concrete wall cracks are permanently sealed with low-viscosity polyurethane resin injected under pressure through surface-mounted ports drilled along the crack length.
Sump pits are sized to accommodate both primary and backup pumps without float interference, and discharge lines are routed to a point at least ten feet from the foundation perimeter.
For severe seepage through block walls, we add core-filling with cementitious grout to eliminate the internal cavities that allow water to travel vertically inside the wall system.
After injection, we verify the repair with a moisture meter reading to confirm that subslab water transmission has been eliminated at the crack location.
We install polycarbonate well covers sized and anchored to each specific well, deflecting direct rainfall while meeting egress requirements and maintaining ventilation.
Our assessment includes a history review of your water intrusion events and a visual inspection of the exterior grading, gutters, and downspouts that affect subsurface drainage.
We prepare a detailed written scope covering all materials, methods, and warranty terms before scheduling any work so you know exactly what you are approving.
All debris is removed daily and the work area is restored progressively so your basement remains usable during multi-day projects.
Your warranty packet includes installation photos, moisture reading logs, and contact information for scheduling future annual inspections.
We had serious standing water every spring for eight years. JCB Waterproofing and Construction installed a full perimeter drain and sump system and we have been completely dry through two wet seasons since.
Professional from the initial phone call to the final walkthrough. They explained every step of the process and answered every question without making me feel rushed.
I called three companies before choosing JCB Waterproofing and Construction. They were the only ones who actually measured the moisture levels and explained what was causing our specific problem before quoting a fix.
