Concrete cracks are a common problem that should not be ignored. Small cracks might not leak for 20 years, however the could also just as easily leak tomorrow!
Inspecting a foundation for cracks is not simple because the foundation walls are buried. Often times the inside of the basement is finished with drywall or wall paneling.
If your basement is unfinished and you can see the crack from the inside, then the repair can be completed in a straight forward manner. If your walls are covered, then the first step that I recommend is a foundation inspection. We use moisture meters and thermal imaging to help locate areas with increased moisture. This helps us target an area for invasive inspection where a section of the wall coverings is removed to inspect further. Some times we are able to use a small camera at first to inspect the area through a 1″ hole before removing a larger section. If you can see a crack on the outside of the foundation we can also use this information to help locate the crack on the inside of the home.
Fortunately once the crack has been located, there is a way to permanently repair such cracks without the need for costly and disruptive excavation. Poured foundation cracks may be repaired by using low-pressure injection of an epoxy or polyurethane foam material. The type of injection will depend on the crack and environmental conditions.
It is always the safest course of action to repair cracks before they leak.
