What is foundation crack repair?
Foundation crack repair addresses water paths through poured concrete foundation walls. Depending on the crack and the conditions around it, repair may involve injection from the inside, exterior access, or further assessment when movement is suspected.
Crack location, direction, width, staining, and active leaking all matter. A site inspection is the responsible way to decide whether a crack is a water-entry issue, a structural concern, or both.
Signs you need crack repair
Water staining
Staining around a crack means moisture has used it as a path.
Active seepage
Drips or wetness during rain should be investigated promptly.
Diagonal or horizontal cracks
Direction and movement help determine the appropriate next step.
Efflorescence
White residue can show that water is moving through the concrete.

Injection vs excavation — when is each used?
Most vertical or diagonal leaking cracks in poured concrete can be injected from the inside. Horizontal cracks, wide cracks, or cracks with movement may need exterior excavation and structural review.
How long does a crack injection last?
A properly injected crack is sealed for the life of the wall under normal conditions. [WARRANTY DETAILS]
Can you fix a crack that is actively leaking?
Yes. Polyurethane injection is designed to stop active water by expanding inside the crack and forming a flexible seal.
