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.
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.
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 Toney, AL 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.
We specify the appropriate polyurethane viscosity for each crack condition, using slower-reacting formulations for complete penetration into deep, narrow cracks and faster-reacting types for active water flow.
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.
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.
Floor-wall joint sealing is frequently included as part of a comprehensive crack repair scope because the joint is the most common source of water intrusion in otherwise structurally sound poured walls.
Crack mapping, moisture readings, and wall plumb measurements are documented in a written report that accompanies your quote.
Written scope defines every material, method, and warranty term before you approve any work so there are no surprises on the invoice.
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.
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.
Our basement had a floor-wall joint that was allowing water in during every heavy rain. JCB Waterproofing and Construction sealed it properly with hydraulic cement and a polyurethane bead. No water in two rainy seasons since. Clean, professional work.
