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 Waterloo, IN 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.
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.
Carbon fiber straps bonded to the interior face of a bowing or horizontally cracked wall provide a permanent tensile reinforcement layer that counteracts lateral earth pressure and stops further wall deflection in its current position.
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.
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.
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.
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.
