Foundation Corner Crack is Nothing Compared with Brick Mortar that Doesn’t Hold

This might be common, but the bigger issue is how solid is the brick mortar between those bricks? Is it the right mortar mix? And will it hold up over time?

The corners of her concrete foundation are cracking off and she wants to know how to repair them. Here’s her testimony:

“The corners of my foundation are slowly falling off. I know I have foundation problems, but I want to put this big chunk back on instead of rebuilding it.

Is there some type of adhesive or bonding agent I can use for this large chunk?”

You bet there’s a compound you can use.

What would you say if I told you there was a miracle concrete epoxy that fit into a standard caulk gun?

Would you be amazed if I told you this repair could be done in about ten minutes by you?

When you go to use it, I want you to cut a piece of an old pliable CD or DVD case and put it between the top of the chunk and the brick mortar. Do NOT put any epoxy on the top of the chunk!

The brick and mortar are moving at different rates than the concrete and I need you to provide a surface where they can slide easily and not get interlocked. This is why the concrete cracked and broke off.

You need to figure out how to hold the chunk in position without moving for an hour or two as the epoxy hardens. This is mission critical to your success.

In addition to the foundation check out the brick mortar in your building to see if it is crumbling, even a little bit. This shows you might have the wrong mortar mix. We test for that.
