Our specialists assess the cause, apply the right materials, and reinforce your concrete walls for long-term durability.
What Is Crack Repair?
Crack repair is the process of restoring strength and stability to concrete walls, foundations, and other structures by sealing and reinforcing damaged areas. Over time, concrete naturally expands, contracts, and settles, leading to visible cracks that can allow water intrusion or weaken the structure. Professional crack repair services go beyond surface fixes to seal and fill the cracks properly, ensuring long-term protection and preventing further damage.
Common Types of Cracks
- Shrinkage cracks: Caused by the natural drying and curing process of concrete. Usually small but still important to seal before moisture gets in.
- Settlement cracks: Occur when the soil beneath your foundation shifts or compresses. These often need full foundation repair to stabilize the structure.
- Structural cracks: Wider, deeper cracks that compromise the integrity of concrete walls or foundations. These require engineered concrete repair to prevent movement or collapse.
- Non-structural cracks: Surface-level or cosmetic cracks that don’t affect stability but can still allow water or pests to enter if not properly filled and sealed.
Risks of Ignoring Cracks
- Water leaks to mold or flooding in basements
- Expanding cracks from freeze-thaw cycles
- Costly foundation repair later on
- Reduced property value and safety concerns
Professional concrete crack repair helps you catch problems early, protecting your structure and extending the life of your concrete walls and foundation.
Common Crack Types & Causes
Not all concrete cracks are the same, and understanding what type you have is key to choosing the right crack repair solution. Different shapes, widths, and directions often point to different underlying issues in your foundation or concrete walls.
Types of Cracks
- Hairline cracks: These are thin surface cracks often caused by drying or minor movement. While they might seem harmless, crack repair services can seal them to prevent moisture intrusion or further spreading.
- Wide cracks: Larger openings indicate deeper structural movement or settling. These typically require more extensive foundation crack repair to restore strength and stability.
- Vertical cracks: Usually caused by natural settlement or shrinkage. They’re common in concrete walls and are often repairable with professional crack repair techniques.
- Diagonal cracks: Often a sign of uneven settlement or shifting soil beneath the foundation. These cracks may widen over time, creating stress points that require expert evaluation.
- Horizontal cracks: The most serious type. Often caused by pressure from expanding soil or water buildup outside the foundation. These require immediate foundation crack repair to prevent wall bowing or collapse.
Common Causes
- Shrinkage: Occurs as concrete cures and loses moisture.
- Settlement: From soil compression or poor compaction beneath the structure.
- Load changes: Heavy construction or added weight can stress existing concrete cracks.
- Thermal cycling: Repeated heating and cooling cause concrete to expand and contract, creating cracks over time.
Repair Methods
There’s no one-size-fits-all solution for crack repair. The best approach depends on the size, type, and cause of the concrete cracks. Professionals use different techniques to secure the structure, prevent leaks, and make surfaces stronger and more durable over time.
Surface Repair & Sealants
For minor concrete repair, surface sealants are often used to close small or hairline cracks. These materials fill surface gaps to block water and debris, preventing the cracks from widening. While this type of crack repair can stop early damage, it’s not always enough for deeper or structural cracks.
Injection Methods (Epoxy & Urethane Foam)
For more advanced repairs, injection systems using epoxy or urethane foam are the preferred solution. These materials are injected deep into the crack to bond and reinforce the concrete walls from within, essentially welding the structure back together.
Learn more about our Epoxy Injection and Urethane Foam Injection methods.
When Injection is Preferred
Injection methods are recommended when:
- The crack extends through the entire concrete wall or foundation
- Water infiltration or pressure is present
- Structural strength needs to be restored
- A long-term, durable solution is needed to enhance stability
These crack repair methods not only secure the structure but also filter out moisture and contaminants, offering a stronger, longer-lasting concrete repair result.
Epoxy Injection vs. Urethane Injection: Key Differences
Both epoxy injection crack repair and urethane injection crack repair are proven ways to fix concrete cracks, but they’re used for different situations. Choosing the right method depends on whether your goal is to restore concrete strength, stop water from seeping, or both. Each injection crack repair technique has its strengths, and understanding when to use each ensures the best, longest-lasting concrete repair results.
| Feature | Epoxy Injection Crack Repair | Urethane Injection Crack Repair |
| Purpose | Structural crack repair to restore concrete strength | Flexible seal for stopping seeping or active leaks |
| Material | Low-viscosity epoxy that hardens to bond concrete | Expanding foam that fills gaps and seals water entry |
| Ideal Use | Dry cracks in walls, beams, or slabs that need strength or restoration | Wet or leaking cracks where flexibility is needed |
| Curing | Slow cure for deep penetration and permanent bonding | Fast-expanding foam that seals in minutes |
| Result | Rigid, high-strength finish that reinforces the structure | Flexible, watertight seal that adapts to movement |
| Longevity | Permanent, structural crack repair solution | Long-lasting waterproof fix that remains flexible |
| Best For | Load-bearing walls, foundations, or large structural concrete repair | Basement walls or slabs with active water intrusion |
When to Use Each Method
- Choose epoxy injection crack repair when the goal is to restore concrete strength and reinforce the structure. Ideal for structural crack repair in foundations, columns, and beams.
- Choose urethane injection crack repair when the problem involves water seeping, shifting, or temperature changes. Perfect for flexible, watertight sealing that fills gaps and adapts to movement.Â
Selecting the right crack repair method ensures the job is done right, providing reliable, long-term protection and extending the life of your concrete repair work.
How the Professional Crack Repair Process Works
Professional crack repair is more than just filling a line in your concrete walls. It’s a detailed, step-by-step process designed to address the problem at its source and ensure long-lasting protection. Our technicians handle each stage carefully to seal cracks from water intrusion and prevent future damage.
Step 1: Inspection & Preparation
Every crack repair begins with a thorough inspection to identify the cause, width, and depth of the crack. The area around the crack is cleaned to remove dirt, loose debris, or old materials so the repair materials can properly bond. For waterproofing cracks, ports are installed along the length of the opening to allow for even material distribution.
Step 2: Injection, Curing, & Finishing
Next, the repair material (either epoxy or urethane) is applied through the ports under controlled pressure. This fills the entire crack internally, sealing it completely and restoring structural integrity. The material is then allowed to cure, typically within about an hour for urethane or longer for epoxy, depending on the type and size of the concrete walls being treated. Once cured, the ports are removed, and the surface is smoothed for a clean finish.
Step 3: Post-Repair Verification
After curing, the team inspects the repaired area to ensure the crack repair was successful and that the surface is fully sealed against water. This verification step confirms that the waterproofing cracks are now fully closed and capable of preventing further damage.
When done properly, this process quickly restores your structure’s strength, seals cracks from water intrusion, and keeps your concrete walls dry, strong, and protected for years to come.

Crack Repair FAQs
Yes. When performed by professionals, injection crack repair offers a long-term solution. Epoxy injections bond concrete walls together to restore structural strength, while urethane injections create a flexible, watertight seal.
It’s rare, but failure can occur if the underlying foundation cracks continue to shift due to soil movement or poor drainage. That’s why identifying the root cause of the crack repair issue is just as important as fixing the surface.
The cost depends on the size, depth, and type of crack, as well as the repair method used. Minor repairs on concrete walls might cost a few hundred dollars, while larger foundation cracks that require injection or structural stabilization may cost more. A professional estimate provides the most accurate range for your specific situation.
Epoxy injections generally take several hours to cure completely, depending on temperature and material type. Urethane foam sets faster, often within an hour, making it ideal for quick sealing or active leaks.
Absolutely. Sending photos of your foundation cracks or concrete walls helps our team quickly assess the situation and provide an accurate recommendation for the right crack repair method.
Properly done crack repair seals the existing crack permanently. However, new cracks may form over time if the soil shifts or water pressure builds up again. Regular maintenance and drainage improvements help prevent future foundation cracks.
