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.
Our interior drain tile systems are sized and sloped to specification, ensuring gravity carries water to your sump pump without clogging or backing up over time.
Block wall seepage is addressed with a combination of core-filling, waterproof parging, and interior membrane systems that stop moisture transfer even under sustained hydrostatic pressure.
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 Fairfax Station, VA. 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 VA 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.
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.
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.
We offer both rigid epoxy injection for structural cracks and flexible polyurethane for non-structural shrinkage cracks, matching the right material to the specific crack type and condition.
We test every installation under simulated load conditions before completing the project, verifying pump cycling, float operation, and battery backup activation before we leave.
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.
After three failed attempts with other companies, JCB Waterproofing and Construction finally fixed our basement for good. The drain system has handled two major rainstorms with zero water in the basement.
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.
