From minor seepage to full basement flooding, JCB Waterproofing and Construction provides engineered solutions that protect your foundation and your investment.
Four reasons why Lexington homeowners trust us with their most important asset.
We design every interior drainage system from scratch based on your basement's actual water entry points, soil type, and floor elevation -- no one-size-fits-all kits.
Porous concrete block and poured walls let groundwater seep through at the mortar joints -- we seal them from the inside with hydraulic cement and crystalline coatings that bond permanently.
Our team is not seasonal labor -- these are career waterproofing professionals who have installed hundreds of systems and troubleshoot the edge cases that stumpers other companies.
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 Lexington, SC. 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.
Interior drain tile is the most reliable and widely proven basement waterproofing method for existing homes in SC 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.
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.
Our written warranty covers both the installed drainage system and the sump pump equipment against defects in materials and workmanship. We recommend scheduling an annual inspection with our team to check that pump floats are operating freely, the battery backup is holding a charge, and the drain system's outlet is unobstructed. Homeowners in Lexington, SC who maintain this schedule rarely experience warranty claims because we catch the small issues before they become large ones.
Our full-service waterproofing menu addresses every water entry point from foundation wall to window well.
We size every drain tile system to the specific hydrology of your basement, ensuring the pipe diameter and sump pump capacity match your worst-case water intrusion load.
Poured concrete wall cracks are permanently sealed with low-viscosity polyurethane resin injected under pressure through surface-mounted ports drilled along the crack length.
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.
Below-grade window wells that collect rainwater are fitted with a dedicated drain at the base of the well, connected directly into the interior perimeter drain system.
We measure moisture levels at multiple points, probe for efflorescence sources, and map every water entry location before recommending any solution.
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.
Our certified crew completes the installation with minimum disruption to your home, working from a phased sequence designed to protect furnishings and maintain basement access throughout.
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.
Excellent crew, fair price, and the basement has been dry for fourteen months now including one of the wettest summers our area has seen. Highly recommend.
