How to Cover Cracks in Foundation Walls

The foundation of your home is the structural support for the walls above it. Due to weight and settling soil underneath the foundation, as well as seeping water, cracks may appear in the foundation over time. Small cracks are often acceptable and do not indicate a serious problem, but larger cracks may let water in from the outside the home, further exacerbating the problem. Attempt to fix cracks as soon as they appear to prevent dangerous situations.
