发帖数: 67 | 1 by code requirement, foundation footing need to extend below local frozen
line, so for cold weather area, the frozen line could be quite deep, so in
that sense, digging for deep founation without getting something out of it is
kind of waste money...
I persoanlly think that's why a lot of houses have basement.
actually frozen earth is not as bad as poor geo condition, like if you have a
house built on clay type of earth
