Q. How do I know a crack in my basement wall is something I should be concerned about?

A. Not all cracks in basement walls (or floors) mean you have big foundation problems, but wall cracks can mean bigger problems than floor cracks when it comes to your basement. Our rule of thumb is that if you see basement wall cracks, it is wise to have an expert take a look. This is truly the only way to determine if there is a larger problem.

Q. Is there a general rule of thumb about the size of basement cracks that mean there is a structural problem?

A. Hairline cracks typically do not need repair and usually don’t indicate a larger problem is going on with your foundation. They can be straight or spider-like. If you note that the crack is larger than a 1/8th of an inch it may be time to have those basement cracks repaired or sealed.

Q. Why are cinder block basement walls more prone to cracking, and when should I be concerned about these cracks?

A. Cinder block basement walls are susceptible to cracking due to their construction with individual pieces held together by mortar. The wear and tear on the mortar over time, coupled with gaps between the blocks, make them more prone to issues such as cracking, water damage, bowing, and buckling. If you notice cracks, especially those that seem to step up or down, or horizontal and vertical cracks, it is advisable to have your foundation inspected promptly.

Q. What is spalling? Is it a sign of structural problems?

A. Spalling is the term that describes when the surface of concrete flakes away. This is typically a sign that the concrete mix was too wet when it was poured. While it may not look very nice, it isn’t a sign that there is a structural problem. If you note it in conjunction with other problems in your basement (or crawl space) however, you may want to have it checked out. If you have water seepage, cracks larger than 1/8th of an inch, or other signs of foundation problems, call an expert.

Q. Can cracks be fixed with foundation piers?

While basement cracks can be a sign of settlement of your foundation, the cracks themselves won’t be repaired by the installation of foundation piers. Certain cracks will have to be sealed. Talk to our professionals for more information.
