Crack in Foundation.....oh my...help!
 
6 Attachment(s)
I was removing my carpet and noticed a crack in the foundation. I have no idea what to do next. The crack runs along the room and ends about 90% across.

What to do?

That appears to be a crack in the floor--not the foundation---

Am I correct?
(the foundation is the concrete walls holding up the house)

First, it will have nothing to do with the sidewalk. Most likely the slab heaved some time ago, so I would say that the best thing to do, is have someone come in and look at it. That will mean also, that they may ask to remove some of the wall covering to look at the inside of the wall to see what is up, due to if you look at the wall below the stucco, there is a crack along the wall. That would mean also, that they may ask to remove the stucco at that level.

If I had to make a educated guess, the floor and foundation most likely either heaved, or dropped if water got under it at that point. That means also that the sidewalk would have to come out, to look below the foundation. Hope your wallet is pretty deep, or your Home Owner's Insurance will cover this.

I am in California and I don't think basements are common. When I see a house go up around here, its just a concrete slab and that's it. The frame is just wood. I guess there is a floor put on top of the concrete slab, that is also concrete? The house is 17 years old.

Assuming both sides of the crack are still on the same level I would really not worry about it. To keep insects out and prevent rapid water intrusion I would try to fill it with caulk.

If you have wet basement problems, the solution is much more profound than just filling cracks. The land must be graded or regraded so that rain water does not collect around the foundation. It is possible you would need a perimeter French drain and a sump pump to correct a wet basement problem.

I agree with allen,you should caulk the crack and not lose any sleep over it.

I live in California, so no basement at this house, just a slab. This is on flat land in a heavily tract area. The crack is even on both sides.

I read online about foundation problems and many people do just what you say, fill the crack.
