Cracks in Cinder Block Foundations

Have you noticed a crack forming in your cinder block foundation? Unlike poured concrete foundations, cinder block foundations (sometimes referred to as “concrete block foundations” or “concrete block basements”) are constructed by stacking blocks on top of one another in brick formation. It’s relatively common for cracks to form in cinder block foundations, but seeing a crack in your foundation is always alarming, so we’ve put together the following resources to help you figure out what to do next.

Different Types of Cracks to Watch Out For

There are many different types of cracks that can form in cinder block foundations, and some are more serious than others:

• Horizontal cracks – Horizontal cracks are the most concerning type of foundation crack because they’re generally caused by bowing walls. In some instances, houses with bowing foundation walls will end up collapsing because they don’t have enough structural support from the foundation. This type of concrete block foundation problem definitely requires the help of an experienced foundation contractor.
• Step cracks – Step cracks—named that because their shape resembles a set of stairs—consist of horizontal and vertical cracks along the mortar joints between cinder blocks. This kind of cinder block foundation crack often isn’t very serious, but under certain circumstances it can be a cause for concern. For that reason, you should seek guidance from a foundation contractor, who will be able to provide personalized insight.
• Vertical/diagonal cracks – Vertical and diagonal foundation cracks are very common, as they usually result from the normal curing process. They tend to be the least worrisome and they can often be addressed using a seal.

These bullets all relate to the shape of the crack. When it comes to width, a good rule to keep in mind is that you should call in a professional for any cracks wide enough to fit a dime.
