We are in contract on a house in northern CA that was built in 1962 and is a poured concrete raised foundation.
We noticed a hairline horizontal crack on the foundation wall above grade that is a few feet long. Our home inspector did not think it was a big deal, but I have always heard that horizontal cracks are bad.
The inspector says that it doesn’t go through to the crawlspace and I we are working on getting a structural engineer to take a look, but I thought I would post it here to see if I could learn anything.
There is efflorescence on the same foundation wall, so I am wondering if it could be rebar corrosion causing this. Our town generally has quite a bit of expansive soil, but it isn’t too bad in this part of town.
There is also some settling in the house, but not in this area.
This doesn’t seem to want to let me attach a picture. How do I make that possible?
Thanks in advance!
