Basement Crack Injection for Poured Concrete Foundations
If you have a vertical crack in a poured concrete basement wall, a full-depth crack injection is the cleanest, most permanent way to stop water intrusion—by injecting the crack itself, not just addressing the symptoms.
Since 1985, The Crack Team has specialized in poured concrete foundation crack repair using a pressurized injection process engineered to stop leaks at their source while allowing natural seasonal movement.

What Basement Crack Injection Is
Basement crack injection is a repair method that seals a poured concrete wall crack through the entire thickness of the wall using a pressurized resin. When done correctly, the crack is sealed at the source—stopping active leaks and preventing moisture vapor from passing through the wall.
Common signs a crack needs attention
- Active seepage during rain or snow melt
- White mineral staining (efflorescence)
- Damp spots, peeling paint, or musty odors
- Vertical cracks in poured concrete basement walls
Most crack injection repairs are completed in 90–120 minutes.
Why Poured Concrete Cracks Behave Differently
Poured concrete walls are strong, but they can develop predictable cracking over time due to soil pressure, shrinkage, settlement, and Michigan’s freeze–thaw cycles. A vertical crack may stay dry for months—or leak immediately—depending on exterior grading, soil saturation, and seasonal movement.
The goal is not to “patch” the interior surface. The goal is to seal the crack itself by injecting a resin into and through the wall, so water can’t migrate through that pathway.
When Injection Is the Correct Repair (and When It’s Not)
Injection is a great fit when:
- The crack is in a poured concrete basement wall
- You have a vertical or diagonal wall crack and/or rod holes
- Water is entering at a specific crack or rod hole location
- You want a permanent repair
Injection may not be the right solution when:
- The wall has major displacement or structural failure
- The issue is a broad drainage/grade problem, not a crack pathway
- The foundation wall is not poured concrete (for example: cinder block or stone)
We’ll help confirm the correct approach during your assessment.
Injection vs. Drain Systems & Excavation
Drain systems and excavation can be appropriate for non-poured concrete foundation walls. But if your issue is a specific poured concrete wall crack or rod holes, injection is the best direct fix because it seals the actual leak pathway.
Crack injection focuses on the cause
- Stops water at the crack
- No digging or disruption
- Fast, clean, permanent repair
Systems focus on managing water
- Moves water after it enters
- More invasive & higher cost
- Better for non-poured concrete walls with broad seepage/drainage issues
Our Step-by-Step Crack Injection Process
- Assess — Confirm the correct repair approach
- Clean — Prepare the crack for proper bonding
- Seal — Install injection ports and surface seals
- Inject — Fill the crack through the full wall thickness

Warranty & Long-Term Performance
Our crack injection repairs are designed for long-term performance. Every repair is backed by a lifetime-of-the-structure transferable warranty—so you can feel confident today and in the future.
Injection is built to flex naturally with seasonal movement while maintaining the seal.
Typical Cost Range
Most poured concrete basement crack injection repairs range from $550–$1,200, depending on crack length, accessibility, and conditions.
