Basement cracks can be caused by a variety of reasons, including leaks, a shifting foundation or mistakes in mixing or pouring the concrete. But basement crack repair doesn't have to be a difficult task; in fact, all it requires are a few simple tools.

Start the repair by removing any pieces of loose concrete that may be wedged within the crack. Use a wire brush and shop vacuum to do the most thorough job. Make sure the surface is also free of dust, oil and dirt.

Apply a concrete patch to the crack, making sure there are no gaps or bubbles. Smooth the patch with a putty knife. If the crack is fairly deep, then the crack may require a second patch. If so, then wait for the first layer to dry before applying the second coat. Seal the concrete patch and allow it to dry for several days.

There are certain cracks that could be the root of structural damage and might require the help of a professional. For example, if a floor crack runs along the foundation walls or a wall crack is causing the wall to shift, then the issue is most likely much deeper than simple do-it-yourself repair.
