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.
Polyurethane injection is specified for cracks where flexibility is a design requirement rather than structural re-bonding. Polyurethane foam expands as it cures to fill irregular voids completely, including cracks that are not perfectly planar. The cured foam remains flexible, allowing the wall to undergo minor seasonal movement without reopening the seal -- a characteristic that makes polyurethane the right choice for active cracks where temperature-driven concrete expansion and contraction may continue. Polyurethane injection is also used in wet crack conditions because the foam reacts with water during its cure, making moisture in the crack an asset rather than an obstacle to the seal.
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.
From hairline seepage cracks to structural horizontal cracking, we have the right fix.
We use two-component structural epoxy formulated for below-grade conditions and sized for the crack width encountered, ensuring complete penetration and full void fill before final curing.
Expanding polyurethane resin fills irregular crack voids completely, including geometry that epoxy cannot fully penetrate, and cures to a flexible seal that tolerates minor seasonal wall movement without reopening.
We calculate strap spacing and quantity based on the measured deflection, wall height, and soil pressure conditions at each job so the reinforcement is engineered for your specific wall rather than generically applied.
We install wall anchor systems in a pattern sized to the wall load and soil conditions, with each anchor location documented in your warranty documentation for future reference.
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.
We seal the floor-wall joint with a combination of hydraulic cement at active leak points and a flexible polyurethane sealant bead over the sealed joint to accommodate minor movement without allowing the seal to crack again.
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.
Carbon fiber installations include verification of bond strength and strap spacing against the engineered design before the job is signed off.
Your warranty packet includes installation photos, crack condition documentation, and recommended monitoring intervals for any cracks assessed as stable but worth tracking.
The carbon fiber repair on our bowing wall was completed in one day and was far less invasive than we expected. No excavation, no major interior disruption. The crew was professional and explained every step of the process.
I was told by two contractors that my diagonal cracks were just cosmetic. JCB Waterproofing and Construction measured the crack width at three points and showed me they were widening. The epoxy injection repair was completed cleanly and the cracks have been stable for over a year.
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.
