here in Texas 95% of all homes are built on a slab, either floating or not. We have such unstable soils that a cellar is not feasible. Our soils shift so much that during a dry spell and then a torential rain, the slab may move over 1 inch in 24 hours.
With these shifting soils, mainly all clay, we do have to do another regional thing: that is to water our foundation.
You need to direct your question to the targeted region that you are intended to live in.
