Water damage to your home or commercial building foundation is another compelling reason to fix sunken concrete. If your sidewalk, steps, driveway, loading dock, or parking lot concrete has sunken in a way that it drives water toward your building’s foundation, you can expect to have moisture issues. Pooling or flooding in your basement or crawl space, mold and mildew growth, and cracks in your foundation walls are expensive repairs that will only get worse if not addressed promptly and leveling your concrete is a fantastic way to prevent these issues.
