Overview
Professional Foundation Crack Repair You Can Trust
Not all foundation cracks are created equal, and knowing the difference is the heart of a proper repair. A thin vertical crack may be harmless concrete shrinkage, while a horizontal or stair-step crack can signal serious pressure or movement. Our first job is always to read the crack correctly, because the wrong repair on the wrong crack wastes money and leaves the real problem unaddressed.
For non-structural cracks that leak, we use injection. Polyurethane injection is ideal for actively leaking cracks because it expands to fill the void and remains flexible, while epoxy injection bonds the concrete and restores tensile strength where structural continuity is the goal. We select the resin based on whether the priority is stopping water, restoring strength, or both, and we inject under pressure to fill the crack through its full depth.
When a crack reflects underlying force rather than simple curing, sealing it alone is not enough. Horizontal cracks and widening separations often point to lateral soil pressure or settlement that must be relieved with wall reinforcement or piering. In those cases we treat the cause, then close the crack, so the repair holds instead of reopening with the next wet season.
A correctly repaired crack should stay sealed and dry for the life of the wall. We back our injection work with a warranty and provide a clear explanation of which category your cracks fall into, so you understand exactly what we are fixing and why. Free inspections mean you can have a worrisome crack evaluated by a professional before deciding anything.
Warning Signs
Signs You May Need Foundation Crack Repair
- Horizontal cracks running along the wall
- Stair-step cracks through block or brick
- Cracks wider than the edge of a coin
- Water or dampness seeping through a crack
- Cracks that grow longer or wider over time
- White mineral deposits trailing from a crack
- Cracks accompanied by wall bowing or bulging
Root Causes
What Causes the Problem
- Concrete shrinkage during initial curing
- Hydrostatic pressure pushing against the wall
- Foundation settlement and soil movement
- Lateral pressure from saturated backfill
- Freeze-thaw cycles expanding trapped water
- Building loads concentrated on weak points
- Tree roots or expansive clay near the wall

How It Works
Our Foundation Crack Repair Process
- 01
Crack Evaluation
We examine each crack's direction, width, and behavior to determine whether it is cosmetic, leaking, or structural. This classification drives the entire repair strategy.
- 02
Surface Preparation
We clean the crack and set injection ports along its length, then seal the surface so resin stays contained under pressure.
- 03
Resin Injection
We inject polyurethane to stop water or epoxy to restore strength, driving the material through the full depth of the crack.
- 04
Reinforcement if Needed
When a crack stems from active force, we add carbon fiber or other reinforcement to relieve the cause before final sealing.
- 05
Cure and Verify
After the resin cures, we remove ports, finish the surface, and confirm the repair is fully sealed and dry.
Compare Your Options
Foundation Crack Repair: How the Options Compare
Epoxy vs Polyurethane Crack Injection
The two injection materials solve different problems. Epoxy restores structural strength to a stable crack; polyurethane flexes and seals against active water. We choose based on whether the crack is structural, leaking, or both.
| Factor | Epoxy Injection | Polyurethane Injection |
|---|---|---|
| Primary purpose | Restores structural strength | Seals against water intrusion |
| Flexibility | Rigid once cured | Flexible, handles movement |
| Best for | Stable, non-moving structural cracks | Leaking or slightly active cracks |
| Water tolerance | Needs a dry crack | Cures even in damp cracks |
Crack Injection vs Carbon Fiber Reinforcement
Injection fixes the crack itself; carbon fiber reinforces the wall against the pressure that caused it. A leaking vertical crack may need only injection, while a cracking, bowing wall needs reinforcement too.
| Factor | Crack Injection | Carbon Fiber |
|---|---|---|
| What it does | Fills and seals the crack | Reinforces the wall against bowing |
| Best for | Isolated vertical cracks, seepage | Walls cracking from lateral pressure |
| Structural movement | Not for ongoing wall movement | Stops further bowing |
| Often combined? | Yes, with reinforcement | Yes, with injection |
Cost Guidance
How Much Does Foundation Crack Repair Cost?
Crack repair is typically priced per crack and by method. These are typical Central Indiana ranges; your free inspection provides an exact figure.
| Item | Typical Range | Notes |
|---|---|---|
| Polyurethane injection (per crack) | $350 – $900 | Leaking vertical cracks |
| Epoxy injection (per crack) | $450 – $1,200 | Structural cracks |
| Carbon fiber strap (each) | $500 – $900 | Wall reinforcement |
| Multi-crack / wall project | $2,000 – $8,000 | Several cracks or reinforcement |
Figures are typical Central Indiana ranges for general guidance only and are not a quote. Your free inspection includes a written, fixed-price estimate for your specific home.
What Drives the Price
- Number, length, and width of the cracks
- Whether the crack is structural, leaking, or both
- Epoxy versus polyurethane versus reinforcement
- Whether carbon fiber or anchors are needed for wall movement
- Access and any finished-wall removal
Warranty & Workmanship
Our foundation crack repair is backed by a transferable workmanship warranty and, where applicable, manufacturer warranties on engineered products. A transferable warranty protects you now and adds value if you sell. We provide all terms in writing before work begins.
Flexible Financing
Foundation work is a major investment, so we offer flexible financing with monthly payment options to fit your budget. Many homeowners qualify and can begin repairs right away. Ask about current financing during your free, no-obligation inspection.
Answers You Can Trust
Foundation Crack Repair FAQs
Vertical hairline cracks are usually shrinkage and not a structural concern, while horizontal cracks and stair-step cracks in block often indicate pressure or movement that needs attention. Width matters too: a crack you can fit a coin edge into deserves professional evaluation. Our free inspection removes the guesswork by classifying each crack accurately.
