Not every crack you find in your foundation wall signals a structural problem, but every crack deserves a professional evaluation because the consequences of misclassifying a structural crack as cosmetic are serious. Our assessment process includes measuring crack width at multiple points, documenting the orientation precisely, checking for horizontal displacement at the crack face, and reviewing the soil and drainage conditions outside the wall. The result is a categorization of the crack as cosmetic, water-entry, or structural -- each with a different repair recommendation.
Horizontal foundation cracks are the category that demands the most urgent attention. A horizontal crack in a concrete block or poured wall indicates that the wall is being pushed inward by lateral earth pressure -- the weight of saturated soil and the force of frost heave pressing against the foundation from outside. Unlike vertical shrinkage cracks, horizontal cracks indicate that the wall is actively deflecting and will continue to do so unless the lateral force is counteracted. Walls that deflect more than one inch from plumb are approaching the threshold at which conventional repair methods may no longer be adequate and more extensive structural remediation may be required. Carbon fiber reinforcement applied to a horizontally cracked wall at the right stage of deflection stops further movement and allows the wall to carry its design loads without progressing to failure.
Epoxy injection and polyurethane injection are the two primary methods for sealing and structurally repairing cracks in poured concrete walls. Epoxy injection produces a bond that is actually stronger than the surrounding concrete, making it the correct choice for cracks where structural re-bonding of the two faces is the goal. The process involves drilling a series of small ports along the crack at intervals calculated to ensure complete penetration, installing surface-mounted injection ports, sealing the visible crack face between ports with epoxy paste, and pumping two-component structural epoxy resin under low pressure until it fully fills the void and appears at adjacent ports. The resin cures within the crack to a solid, high-strength bond that is permanent and fully water-resistant.
Soil settlement beneath footings is an independent cause of foundation cracks that requires evaluation separately from the wall repair itself. When soil compresses or washes out from beneath a footing, that section of the foundation wall loses its support and the wall may develop diagonal cracks as the unsupported section deflects downward. In these cases, crack injection addresses the symptom while leaving the root cause unresolved. Our assessment includes a review of grading, drainage, and visible footing conditions to identify signs that settlement is active. Where settlement is a factor, we coordinate the repair approach to address both the crack and the soil condition that created it, preventing recurrence after the crack is sealed.
Six targeted repair services covering every foundation crack condition in Two Rivers, WI homes.
Structural epoxy injection bonds the two faces of a poured concrete crack together with a cured material that exceeds the tensile strength of the surrounding concrete, producing a truly permanent structural repair.
Polyurethane injection is the correct choice for actively weeping cracks where water presence would compromise epoxy adhesion -- the foam reacts with moisture to accelerate its cure and seal the void from the inside out.
Strap installation requires no excavation of the foundation exterior, minimal removal of interior finishes, and leaves a wall surface that can be painted over after the bonding adhesive cures.
Where bowing wall deflection exceeds the threshold for carbon fiber repair alone, a wall anchor system provides mechanical resistance by connecting the deflecting wall to stable soil beyond the active failure zone through a tension rod and plate assembly.
Severe stair-step cracking that indicates ongoing settlement is evaluated for root cause before repair so we are not sealing a crack that will reopen as the movement continues.
The joint where a poured concrete wall meets the footing is a construction cold joint that is prone to opening as the wall and footing settle and move at slightly different rates, creating a direct water pathway into the basement.
Crack mapping, moisture readings, and wall plumb measurements are documented in a written report that accompanies your quote.
We match the repair method to the specific crack condition -- epoxy for structural re-bonding, polyurethane for active water and flexible seal requirements, carbon fiber for bowing walls.
Our certified crew executes the repair to specification, maintaining injection pressure logs and documenting material volumes consumed to verify complete crack penetration.
Your warranty packet includes installation photos, crack condition documentation, and recommended monitoring intervals for any cracks assessed as stable but worth tracking.
We had a 14-foot horizontal crack in our block wall that two other companies dismissed as not serious. JCB Waterproofing and Construction came in, took actual measurements, and explained exactly why it needed carbon fiber straps immediately. The repair looks clean and the wall has not moved since.
The written quote was detailed and transparent. They explained what type of crack I had, why they were recommending epoxy over polyurethane, and what the warranty covered. That level of professionalism made the decision easy.
I appreciated that they did not try to upsell me on a full drain system when crack injection was the right fix for my situation. They solved the actual problem and the repair has held completely.
Our certified specialists have seen every type of foundation crack in WI -- we know exactly what it takes to fix yours properly.
