Repair a Foundation Corner

Fix a Foundation Pop

A Mason I am not.

But when my Realtor hubby asked me to help him repair a foundation corner pop, I figured I could probably handle it.

A “corner pop” is when the corner of a house’s foundation cracks, and pops off.

This isn’t usually a structural issue, but it can cause a few problems. Namely, it creates an access for all kinds of little critters to get in, and it can cause your brick to crack or fall off due to lack of support.

Fortunately, correcting the problem is a cheap and easy fix. All you need is some Quikrete , a trowel or blade, and a little bit of time. I would say this is a beginner-to-intermediate project.

To start off this endeavor, mix some quik-crete in a small bucket. You want it to be a little bit “dry” so it holds together. If it’s too wet, it will just slide right off of the foundation. Once the concrete is mixed, start at the bottom of the foundation corner defect and just start filling it in, creating a rough corner as you go.

Then use a blade or trowel to smooth the sides and make a sharp corner. Keep the blade wet, and work the concrete by using a short back and forth motion to shape it.

The next day, simply continue on the process until the corner is completely filled, or your concrete starts sagging again. Fortunately, this was only a two day project, since it was a fairly small pop.  Once the foundation corner is reconstructed, smooth the repair out using a wet paint brush, and a thin coat of concrete “juice” to blend the patch into the old concrete.

After the smoothing coat is done, so it the patch! It just needs to cure, and you will no longer have a “critters enter here” sign on your house, and your brick cladding will stay put. Now, wasn’t that easy!?
