Standing water, damp walls, and musty odors signal hydrostatic pressure building against your foundation -- JCB Waterproofing and Construction stops it at the source.
Four reasons why Andover 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.
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.
Our team is not seasonal labor -- these are career waterproofing professionals who have installed hundreds of systems and troubleshoot the edge cases that stumpers other companies.
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.
Hydrostatic pressure is the invisible force behind nearly every basement water problem homeowners face in Andover, MN. 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.
A well-installed interior drain tile system is designed around the specific hydrology of your property. Basements in Andover 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 Andover, MN who maintain this schedule rarely experience warranty claims because we catch the small issues before they become large ones.
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.
Poured concrete wall cracks are permanently sealed with low-viscosity polyurethane resin injected under pressure through surface-mounted ports drilled along the crack length.
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.
After injection, we verify the repair with a moisture meter reading to confirm that subslab water transmission has been eliminated at the crack location.
Below-grade window wells that collect rainwater are fitted with a dedicated drain at the base of the well, connected directly into the interior perimeter drain system.
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.
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.
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.
