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.
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.
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.
From hairline seepage cracks to structural horizontal cracking, we have the right fix.
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.
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.
We repair stair-step cracks by tuck-pointing the affected mortar joints with a compatible mortar mix matched to the existing wall, reinforcing corner crack locations, and applying a crystalline waterproofer to the repaired area to prevent water intrusion at the newly bonded joints.
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.
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.
Written scope defines every material, method, and warranty term before you approve any work so there are no surprises on the invoice.
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.
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 IN -- we know exactly what it takes to fix yours properly.
