Foundation Crack Repair
Foundation crack evaluation and repair coordination for Bergen County homeowners. Epoxy injection, polyurethane foam for active leaks, carbon fiber reinforcement, and waterproofing — managed by a registered NJ contractor.
Foundation Crack Repair & Sealing
Foundation cracks — whether hairline or actively leaking — require professional evaluation before any repair decision. Bergen Restoration assesses crack width, pattern, and moisture conditions, then coordinates the appropriate repair method: epoxy injection for stable cracks, polyurethane foam for active seepage, carbon fiber reinforcement where lateral movement is a concern, and waterproofing membrane over repaired sections. When drainage is the root cause of water pressure, we coordinate that work as well.
- Crack evaluation — width, pattern, and moisture assessment
- Epoxy injection coordination for stable, non-active cracks
- Polyurethane foam injection for active or leaking cracks
- Crack routing and surface sealing
- Interior carbon fiber strap reinforcement where appropriate
- Waterproofing membrane application over repaired sections
- Drainage coordination when water infiltration accompanies cracking
- Structural engineering referral when cracks suggest movement or settlement
Bergen Restoration does not perform structural engineering. Where cracks suggest structural movement or settlement, we coordinate referral to a licensed structural engineer as part of the evaluation.

Crack Evaluation & Diagnosis
Hairline cosmetic, active leak, structural movement, or settlement — each gets a different repair. Width, pattern, and moisture all read together.
- Bergen County residential renovation experience across kitchens, bathrooms, basements, additions, and water-damage rebuilds.
- Written scope, sequenced milestones, and documented material selections before any demolition begins.

Epoxy Injection (Stable Cracks)
Two-part structural epoxy injected via surface ports bonds the concrete back together. Best for non-active hairline cracks.

- Written scope, sequenced milestones, and documented material selections before any demolition begins.

Polyurethane Injection (Active Leaks)
Hydrophilic polyurethane expands when it contacts water, sealing active leaks. Different chemistry, different application than epoxy.
- Bergen County residential renovation experience across kitchens, bathrooms, basements, additions, and water-damage rebuilds.
- Written scope, sequenced milestones, and documented material selections before any demolition begins.

Carbon Fiber Reinforcement
Carbon-fiber strips bonded across the crack resist further movement. Used where structural assessment shows lateral pressure or settlement risk.

Drainage Root-Cause Resolution
Most foundation cracks are water-pressure related. Crack repair without drainage upgrade is a short-term fix. We coordinate both.
- 24/7 emergency intake; same-day or next-day response typical when crews and site conditions allow. Exact timing depends on weather, call volume, location, access, and crew availability.
- Industrial dehumidifiers and air movers sized to room volume and material type. Daily moisture readings until dry standard hit.
- Coordination with licensed plumbers, electricians, and adjusters on scope and documentation throughout.

Cost & Timeline Guide
Single epoxy injection $400–$900 in 2026. Polyurethane on active leak $700–$1,500 per crack. Carbon fiber strap $400–$800 each. Full drainage tie-in $4,000–$12,000+.
- Scope tiers, material grade, and labor splits drive total. Mid-range projects typically run 60–70% of high-end equivalents on the same footprint.
- Hidden costs to plan for: permit fees, dumpster, dust protection, and any required structural or trade work uncovered during demo.
- Bergen County projects budget 1–3% for permits and 5–10% contingency on most renovation scopes.

Your Foundation Crack Repair Process
Inspect & diagnose
Evaluate crack width, pattern, location, and whether water is present or seeping. Determine whether the crack is structural, cosmetic, or moisture-driven.
Select repair method
Recommend epoxy, polyurethane, carbon fiber reinforcement, or engineering coordination based on findings. We explain the options before anything is scheduled.
Prep & seal
Clean the crack, install injection ports where applicable, inject sealant, and apply surface seal. Carbon fiber straps installed where lateral pressure is a concern.
Waterproof & coordinate drainage
Apply waterproofing membrane over repaired sections. If water pressure from drainage is the root cause, coordinate French drain, sump pump, or yard drainage work.
Frequently Asked Questions
Hairline cracks (less than 1/8 inch) are usually cosmetic. Cracks wider than 1/4 inch, cracks that leak water, horizontal cracks, or step-crack patterns that suggest settlement or structural stress need professional evaluation.
In many cases, yes. Interior epoxy or polyurethane injection addresses most non-structural cracks from inside the basement. Active or leaking cracks may benefit from injection combined with exterior waterproofing or drainage work, depending on the source of water pressure.
Epoxy seals stable hairline cracks. Polyurethane foam injection works on active leaks. For best long-term results, crack repair is paired with exterior waterproofing or drainage upgrades where water pressure is the root cause.
Yes. Finish basement walls only after cracks are evaluated and sealed. Finishing over an active leak wastes the investment and risks water damage to new flooring, framing, and drywall.
