Foundation cracks
Posted on 11/26/24 at 8:18 pm

I’m doing some flooring work and I found a couple of cracks that I’m concerned with after removing the old carpet. They are 1/8” at their widest and run almost the length of the respective bedrooms but don’t extend to the exterior walls. Is this worthy of having someone assess? I don’t have any sticking doors/windows or cracks in the sheet rock.

More than likely it is from temperature and shrinkage (non structural).
Keep an eye on adjacent walls for any cracking propagation..

Sounds like the foundation is doing fine and reinforcement is doing it's job. All slabs have cracks, that's just the way things are. If it was 1/4 in. and unlevel then I'd maybe have someone take a look.
What type of flooring will you be installing?

Structurally, you're fine, but just make a note that if the crack goes all the way through the slab, you could have an (unseen) entry point for termites. Guess how I know.....

There are two types of concrete.
One that is cracked and one that will eventually crack.
Seriously though, sounds like you are fine being only 1/8" at the widest and you aren't having any cracking in the wall finish.

This is correct. Been in the concrete industry for almost 20 years. It always cracks. Likely its shrinkage and not structural.

May want to fill it for insect/termite reasons, and potentially moisture reasons, right?

That's normal. If there were issues with the soil the concrete was poured on you would also see some cracks that are pressing together causing spawl.

Vapor barriers are also termite barriers so as long as you have a minimum of 10 mil poly that was installed correctly you should still be good. Of course without seeing it properly installed before the slab was poured you'll never know without breaking out concrete.

I honestly wouldn’t worry about it if the two sides of the crack are level relative to one another.
If you just want to fill in the gap, you can buy some concrete patch at the Home Depot/ Lowes. And apply it with a putty knife. It works very well.

All concrete cracks, houses I've built, cable foundation. When doing driveways, I use a bunch of expansion joints, keyway and fiber. My house built in 93, I used fiber for the driveway, very small cracks.
