Wall seepage and floor cracks let moisture invade your home year-round. Our certified team in Vancouver delivers lasting waterproofing that holds.
Four reasons why Vancouver 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.
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.
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 Vancouver 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 WA 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.
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.
Six core services covering every source of basement moisture in Vancouver homes.
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.
Basement floor cracks that allow water infiltration from below are treated with polyurethane injection resin pumped under pressure to fill the void and bond with surrounding concrete.
Failing or undersized window well flashing and frame seals are replaced as part of every window well drainage project to address all water entry paths simultaneously.
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.
