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.
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.
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 Port Washington 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 Port Washington 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.
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 Port Washington, 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 Port Washington 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.
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.
The finished surface is coated with a heavy-bodied elastomeric masonry waterproofer that bridges hairline cracks and resists surface moisture transmission year-round.
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.
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.
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.
The quote was detailed, the crew was on time, and the work was exactly as described. They even patched the concrete so neatly you can barely tell there was a drain trench cut.
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.
