From minor seepage to full basement flooding, JCB Waterproofing and Construction provides engineered solutions that protect your foundation and your investment.
Four reasons why Grand Island homeowners trust us with their most important asset.
We design every interior drainage system from scratch based on your basement's actual water entry points, soil type, and floor elevation -- no one-size-fits-all kits.
We treat every crack, joint, and tie rod penetration as a potential failure point and address each one individually rather than painting over the problem.
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.
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 Grand Island 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 Grand Island 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.
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.
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.
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.
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.
Our quotes include alternatives at different investment levels so you can choose a phased approach if budget requires it.
All debris is removed daily and the work area is restored progressively so your basement remains usable during multi-day projects.
We perform a complete post-installation inspection, take final moisture readings, and walk you through the system before issuing your written warranty documentation.
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.
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.
