From minor seepage to full basement flooding, JCB Waterproofing and Construction provides engineered solutions that protect your foundation and your investment.
Four reasons why Greensboro homeowners trust us with their most important asset.
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.
Our quotes include the scope of work, materials specified by brand and model, warranty terms, and the payment schedule -- everything you need to compare us fairly.
Most homeowners in Greensboro do not realize that a wet basement is not simply a waterproofing problem -- it is a structural warning sign. Hydrostatic pressure that pushes water through walls does not stop pushing when the water is gone. It continues to stress the concrete and masonry, leading to horizontal cracks in block walls, inward bowing of poured walls, and undermining of the footing system. Addressing the symptom without understanding the root cause means spending money on solutions that fail within a few seasons.
Interior drain tile is the most reliable and widely proven basement waterproofing method for existing homes in NC because it manages water that has already entered the wall cavity rather than attempting to stop it at the exterior. The system consists of a perforated pipe, encased in clean washed gravel, installed at or below the footing level in a channel cut along the perimeter of the basement floor. Water that enters the wall-floor joint, seeps through cracks, or migrates through porous concrete flows into this channel and is directed by gravity to a sump basin. A properly sized sump pump then discharges the water away from the foundation. When correctly installed, this system operates indefinitely without clogging because the inlet is protected from sediment by the gravel bed and a filter sock on the pipe.
Wall seepage in block-construction basements is distinct from crack injection because the water is not coming through a single discrete opening -- it is migrating through the porous masonry itself and weeping through the mortar joints. Effective treatment requires sealing the interior face of the block with a hydraulic cement parging coat, followed by a crystalline waterproofing compound that reacts with moisture to form insoluble crystals inside the concrete matrix. This approach stops the migration rather than coating over it, producing a result that actually strengthens with repeated moisture exposure rather than degrading. For severe seepage, core-filling the hollow block cells with grout eliminates the cavity that allows water to travel vertically inside the wall before finding an exit point.
Window wells in below-grade basement windows are a frequently overlooked water entry point. When the well fills with rainwater faster than the soil at the bottom can absorb it, that water presses directly against the window frame -- typically the weakest point in the entire basement envelope. We address window wells with a dedicated drain assembly at the base of the well, tied into the interior perimeter drain system, combined with a properly sized and anchored polycarbonate cover that deflects rain while allowing emergency egress.
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.
Our full-service waterproofing menu addresses every water entry point from foundation wall to window well.
Our drain tile installations use commercial-grade perforated pipe with filter sock protection, gravel bedding, and a concrete topping restored to match your original floor.
Injection ports are removed after cure and the wall surface is patched flush, leaving a clean repair with no visible hardware remaining on the wall face.
We test every installation under simulated load conditions before completing the project, verifying pump cycling, float operation, and battery backup activation before we leave.
The finished surface is coated with a heavy-bodied elastomeric masonry waterproofer that bridges hairline cracks and resists surface moisture transmission year-round.
In cases where floor heaving or settlement accompanies the crack, we supplement injection with a partial slab replacement to restore a flat, properly sealed surface.
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.
We perform a complete post-installation inspection, take final moisture readings, and walk you through the system before issuing your written warranty documentation.
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.
