About Foundation Wall Crack Injection
Cracks in your foundation walls are a common entry point for water. Even small cracks can let in moisture, and over time they can widen due to freeze-thaw cycles and soil pressure. Crack injection seals these openings from the inside, stopping water intrusion without exterior excavation.
We inject specialized materials into foundation cracks that fill the entire void and cure to form a waterproof seal. This prevents water from entering and stabilizes the crack against further movement.
Foundation crack injection is a cost-effective repair for cracks that aren't caused by structural failure. For actively leaking cracks or cracks that appear after heavy rain, injection is often the most practical solution.

Our Process
How we approach foundation wall crack injection projects from start to finish.
Inspection
We examine the crack to understand its cause, size, and whether it's actively leaking.
Preparation
We clean the crack area and install injection ports along its length.
Injection
We inject sealant material under pressure, filling the crack from front to back.
Finishing
We remove the ports and patch the surface so the repair is minimally visible.
Foundation Wall Crack Injection FAQs
Common questions about this service.
What type of cracks can be injected?
Injection works best for vertical or diagonal cracks in poured concrete walls. It's effective for hairline cracks up to about 1/4 inch wide. Very wide cracks or cracks in block walls may need different approaches.
Is crack injection a permanent fix?
Injection seals the existing crack, but it doesn't prevent new cracks from forming elsewhere. If the underlying cause (like poor drainage) isn't addressed, you may see new cracks over time.
How long does the injection material last?
Quality injection materials are designed to last the life of the foundation. The repaired area is often stronger than the surrounding concrete.
Can cracks be injected from outside?
Most crack injection is done from inside the basement, which is less invasive and usually more effective. Exterior injection is possible but typically requires excavation.
