Is It Possible to Fix the Stair-Step Cracks in a Block Foundation?

Concrete block foundations consist of several blocks held together by caulk, mortar, or a similar substance. These types of foundations are on the older side, but they can help keep your home in one spot for years at a time. That said, block foundations are just as prone, if not more so, to the kind of damage that might put the structural integrity of your home at risk. Because these foundations are made of several individual pieces, you may readily find yourself contending with a stair-step crack should you identify any damage. Stair-step cracks, as the name suggests, tend to form along the mortar lines binding your foundation together. These cracks are indicative of excessive hydrostatic pressure and its impact on your home.  

Exploring Your Options  

You do, however, have the option to fix a stair-step crack should one develop in your block foundation. You should not attempt to go about the process of fixing such a crack on your own. Fixing a cracked foundation often requires you to excavate some of said foundation, a process that can take a considerable amount of time if you do not have the proper tools on hand.  

Instead of trying to repair your foundation on your own, you can reach out to the professional contractors in your area. With their guidance and experience, you can determine what method of repairing your foundation—piers, for example, might best suit your needs.  

Once your foundation is back up to snuff, note that you can also discuss potential waterproofing measures with the professionals in your area. This way, there will be less of a chance of stair-step cracks forming along the same lines or along alternative lines in the months or years to come.
