From minor seepage to full basement flooding, JCB Waterproofing and Construction provides engineered solutions that protect your foundation and your investment.
Four reasons why Selden 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.
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.
Every technician on our crew holds current certification in basement waterproofing systems and participates in ongoing training as products and methods evolve.
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 Selden 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.
A well-installed interior drain tile system is designed around the specific hydrology of your property. Basements in Selden that sit in naturally high water table zones require larger-diameter pipe and higher-capacity pumps than basements that only collect surface runoff during heavy storms. Our assessment process measures both the volume and the frequency of water intrusion to right-size every component -- from the pipe diameter to the pump horsepower and battery backup capacity.
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.
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 Selden, NY 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 Selden homes.
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.
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.
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.
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.
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.
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.
