Standing water, damp walls, and musty odors signal hydrostatic pressure building against your foundation -- JCB Waterproofing and Construction stops it at the source.
Here is what sets our basement waterproofing team apart from the rest.
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.
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 deliver detailed written quotes that break down every material and labor cost -- no surprise line items appear on your final invoice that were not on the original estimate.
Hydrostatic pressure is the invisible force behind nearly every basement water problem homeowners face in Chatham, IL. When soil around your foundation becomes saturated -- whether from heavy rain, snowmelt, or a high water table -- it exerts outward and downward pressure against concrete walls and floor slabs that can exceed hundreds of pounds per square foot. Over time, this pressure finds the smallest weakness: a tie rod hole, a cold joint between wall and footing, a shrinkage crack in poured concrete, or a deteriorated mortar joint in block construction. Once water finds its path, that path widens with every wet season until a trickle becomes a flood.
Interior drain tile is the most reliable and widely proven basement waterproofing method for existing homes in IL 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.
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.
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.
We install pedestal and submersible sump pumps from commercial-grade manufacturers and include a battery backup unit as standard on every new installation.
Hollow-core concrete block walls are treated with hydraulic cement parging and crystalline waterproofing compound that bonds into the block face and eliminates surface seepage.
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.
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.
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.
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.
