LESLIE: Mike in Louisiana is on the line with a question about concrete. What’s happening?
MIKE: I have a crack in my home's foundation and I am wondering how to stop it.
TOM: So is this a basement foundation or a crawlspace foundation? What’s it look like?
MIKE: I have a slab. It’s just a crack in the concrete. Goes pretty much all the way across on one end of the house.
TOM: OK. So does it – is it the floor or do you see it from the outside? Where are we seeing this?
MIKE: Just in the floor. I just see it in the floor. I don’t see it on the side. Looked at twice on the outside and I haven’t seen it.
TOM: Alright. So that might not be part of the foundation. Because when you have a slab-on-grade house, the floor area itself is actually not part of the foundation; only the perimeter is. So that’s a pretty standard crack repair. What you want to do is go to a home center and pick up a QUIKRETE – Q-U-I-K-R-E-T-E – epoxy-based or patching compound. And you can apply the Quikrete to the crack to fill it.
There’s a number of different types of this. Some of it comes in a tube that you can apply with a caulk gun and others you mix up. But it has to be a patching material because the – otherwise, it won’t stick to the old concrete. Then what you do is clean out that crack, you apply the patch, let it dry and you’re good to go.
MIKE: OK. I appreciate it.
TOM: You’re welcome. Good luck with that project. Thanks again for calling us at 888-MONEY-PIT.
