Real cracks. Real fixes.

Homeowner had an active wall leak at a vertical structural crack. Water had been bleeding through during heavy rain and seasonal soil pressure, and prior surface patches had failed. Inspection revealed multiple related cracks at the same property, indicating ongoing wall flexing rather than a single isolated failure.

We injected expandable polyurethane into the crack to immediately stop water transmission and fill the full depth of the wall. Once watertight, we bonded structural reinforcement (carbon fiber strap system) across the crack to eliminate any future movement or expansion. Additional cracks at the same property were documented and treated with the same protocol.

Multifamily basement with a leaking wall crack. Water tracked down the wall during every rain event and pooled near utility lines, with visible staining and efflorescence around the leak path. Tenants had reported the recurring moisture for months before professional inspection.

We injected expandable polyurethane to seal the crack at full wall depth, stopping water transmission immediately. Structural reinforcement was then applied across the crack using carbon fiber strap bonding, eliminating any further movement and locking the wall back into a continuous structural element.

During the original construction of this Purchase, NY home, the foundation cracked before the build was complete. The original builder injected an improper material into the crack and assured the owner the foundation was sound. Four years later, the homeowner discovered a significant leak. When the wall was opened up, the original crack was found to extend across the entire home, the failed builder repair had only masked the symptom for a few seasons.

Full restoration: we performed structural masonry repair across the entire crack length using a high-modulus material superior to the original concrete, applied carbon fiber + Kevlar reinforcement bands across the affected wall, and installed a complete waterproofing system on both the interior and exterior wall faces. The wall now performs structurally as a continuous element and is fully watertight, with our lifetime transferable warranty.

270-year-old historic Rye building developed a significant structural crack after recent seismic activity in the region. Older masonry and stone foundations are particularly vulnerable to seismic loads, the original construction predates any modern lateral-load design. The crack threatened to propagate further with each subsequent ground vibration if not stabilized.

Carbon fiber and Kevlar stabilization bars installed across the crack at calculated intervals. Each bar transfers tensile load across the gap, restoring continuous structural behavior to the wall while keeping the visible historic appearance intact. Repair was completed using methods compatible with the older masonry, no modern poured-concrete techniques that would have damaged the original.

Property with multiple active structural cracks. The basement block wall had stair-step and water-staining damage from cumulative soil pressure, and a long zigzag slab crack ran across the garage floor with visible separation between sides. Both required structural reinforcement, not surface patching, because the underlying movement was ongoing.

On the wall, we prepped the substrate and bonded carbon fiber mesh wraps across the affected sections with structural epoxy, locking the wall back into a continuous structural element. On the slab, we drilled and installed carbon fiber + Kevlar stabilization bars perpendicular to the crack at calibrated intervals. Each bar transfers tensile load across the slab gap, restoring monolithic slab behavior and eliminating future widening.

Norwalk home where exterior excavation revealed the original construction had no proper footer beneath a section of foundation wall. The wall had been bearing on insufficient subgrade, with rebar exposed and the structural support inadequate for the load above. This is a serious structural defect, the wall was settling and cracking because there was no foundation underneath it.

We rebuilt the footer first, installing a new foundation footer with significant load-bearing capacity, roughly 10× the structural support of what was originally there. Once the new footer was poured and cured, we performed structural reinforcement on the wall above to lock the new structural assembly into a continuous load path. The result is a foundation section that performs better than the original construction ever did.

Mount Kisco home with a major structural crack on the basement wall. Homeowner reported a long history of leaks, water repeatedly entering through the crack during heavy rain and snowmelt. Multiple prior cosmetic repair attempts had failed because neither the structural movement nor the underlying water transmission had been addressed.

Two-part fix: full structural reinforcement of the wall using carbon fiber straps to resist the soil pressure driving the crack, then a waterproofing system applied to the wall to stop water transmission permanently. Together, the repair eliminates both the structural cause of the cracking and the moisture path that was allowing water in.

Westport property with footer-related structural cracking. Inspection revealed the original footer was undersized for the load above it, the original construction had been built with insufficient foundation support. Over time, the underbuilt footer had compressed and shifted, transmitting movement into the wall above as visible cracking.

Footer repair and reinforcement. We rebuilt the affected footer section with a much higher-capacity assembly, properly sized for the actual structural load above. Rebar density was significantly increased over the original, and the new footer was tied into the existing foundation in a continuous load path. The wall above stabilized once the underlying support was correct.

Homeowner had been chasing a chronic basement leak that surface patches and interior fixes couldn't stop. Every interior repair held for a season and then failed again. Inspection showed the real source: water was tracking down the exterior foundation wall through dirty backfill loaded with stones, finding every microcrack on its way down. Any interior treatment would only ever be moving the symptom around — the actual fix had to happen on the outside.

We hand-excavated a full trench down the exterior of the affected basement wall, all the way to the footer. The original backfill was packed with construction-era stones that had to come out by the bucketload before we could even see the wall (see the photo of the pile we removed). With the wall exposed, we cleaned and prepped the concrete, repaired any visible cracks at full depth, and applied a continuous black rubberized waterproofing membrane across the entire exterior face. Drainage was corrected at the base, the trench was backfilled with clean material, and the wood bracing/forms were installed during dig to keep the trench safe to work in. The basement has stayed dry since — exterior fixes do that, when they're done properly.
