Written coverage on all repair work
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.
The repair method matched to horizontal cracks depends on the degree of deflection and the construction type of the wall. For poured concrete walls with deflection below critical thresholds, a carbon fiber strap system bonded to the wall face with structural epoxy provides a tensile reinforcement layer that counteracts the lateral earth pressure. For block walls, carbon fiber straps bonded to a plate assembly anchored into the slab and rim joist provide the same function. In both cases the straps are virtually invisible after installation and do not require interior space to accommodate them.
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.
Bowing walls in block construction represent a specific category of damage where the masonry units have displaced outward of plumb due to lateral soil pressure. Depending on the degree of bowing, repair options range from carbon fiber strap reinforcement that stops further movement to wall anchor systems that attach to stable soil beyond the active failure zone and provide a mechanical load path that reduces the net lateral pressure on the wall. Our structural assessment determines which approach is appropriate based on the measured deflection, the soil conditions, and the construction history of the wall.
Six targeted repair services covering every foundation crack condition in Cordova, AL homes.
Every epoxy injection job is documented with before-and-after photos and a report of injection pressures and resin volumes consumed to verify full crack penetration.
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.
We measure every crack for width, orientation, and displacement, review the soil and drainage context, and classify each crack by type and severity before recommending any repair method.
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.
A written warranty is issued on project completion, covering the repair against reoccurrence under normal conditions for the warranty period stated in your contract.
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.
