Block Foundation - Is this regional?
We live in suburban Chicago but have been house hunting and looking at some in process builds in western North Carolina. Almost everything we look at has a block foundation, something that is largely unheard of here. Certainly there are climate differences from Chicago to NC but beyond that, we're having trouble understanding why we don't see poured concrete foundations there. It doesn't seem that there would be a significant cost difference once you account for the labor required for the block, but maybe I'm missing something? Admittedly, our comfort is in what we're familiar with, poured foundations, but obviously lots of people live in lovely houses with block foundations and are perfectly comfortable.
Can someone do a simple run down of engineering differences, cost differences or other significant differences for me? I appreciate your input.
