Before beginning work on the surface, it is necessary to discover why the crack initially started. Most often a basement floor crack is a result of wear and tear. But if you notice a heavily cracked area or a crack that runs parallel to the foundation, then the issue may be the result of structural damage.

Start by removing debris, such as loose pieces of concrete that may be wedged within the crack. Use a wire brush and shop vacuum to make the process easier. 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 uneven areas. Smooth the patch with a putty knife. If the crack requires a second patch, 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. Certain cracks may be the result of structural damage and might require the help of a professional engineer or foundation specialist.
