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.
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.
We document every installation with before-and-after photos, moisture readings, and a written record so you have evidence of the work performed and its conditions.
We explain every line item in plain language because customers who understand what they are paying for are the ones who trust us with their second home or rental property later.
Most homeowners in Oneida 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 WI 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.
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 Oneida, WI who maintain this schedule rarely experience warranty claims because we catch the small issues before they become large ones.
Six core services covering every source of basement moisture in Oneida 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.
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.
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.
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.
We measure moisture levels at multiple points, probe for efflorescence sources, and map every water entry location before recommending any solution.
Our quotes include alternatives at different investment levels so you can choose a phased approach if budget requires it.
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.
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.
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.
