Ok so over the weekend, I'm at home and I hear this loud pop/crack noise come from a bathroom in the front of the house. I go to see wtf just happened, and the sound happened 3-4 more times while I was in the bathroom (think clapping your hands as loud as possible, but a little louder) - sounded like it came from inside the walls but I could feel the vibration reverberating in the floor with each pop.

On further inspection, I noticed new hairline cracks in the flooring - these were definitely not there prior (see pics below). There are no cracks in the walls that I can see. House was built in 2019 in newly developed subdivision.

One side note is that I was watering my dry-arse dying grass on that side of the house at the time, adjacent to the affected bathroom. I did some reading and it looks like watering dry clay can cause the foundation to expand and possibly caused this issue? Idk.

Anyways my main question is: do I just go on my merry way and ignore it, chalk it up to a temporary expansion of underlying clay? Or is this an issue that I need to have checked out? TIA

First off, that sucks.

Have you noticed a crack in the wall or foundation on the exterior? Foundation settling with some hairline fractures in the cement is quite normal, and it will transfer to tile above, but, if you see something outside, you may have an issue. If it bothers you, the tile can be pulled up and a latex based adhesive can be used to reset the tile and it will not transfer foundation hairline cracks to the tile above it.

I just had this happen as well. I'm in NW Fort Worth and on a well, which is not able to produce enough water to keep things wet enough. I've developed gaps between the slab and grass and we have high clay soil.

I'm not sure you could've put down enough water to cause this happen. I would think the crack occurred because a side of the house dipped due to the shrinking clay. My crack was linear traveling across a 10 ft area.

I don't think it is uncommon. I've heard of similar things happening in extreme cold. I had some de-lamination a decade ago when we had a heavy rain after a period of drought. They didn't crack in this case, but they still sound hollow. It was a hell of a loud series of pops...sounded like gunfire.

Very common. I'm sure you did not cause it.

Lets get some rain and see how things start to "settle down."

I did Foundation Repair for a decade. The ground around your slab is just too dry, causing your slab to sink. Its almost always the corners that sink first. A little rain and your slab will be back to where it was.
