I live in the frozen northland and we have to have footings below the frost line to prevent frost heave. I saw that on the Austin project they had a heavy rain and the ground swelled with the water and heaved the house. I would think that a house heaving from water would be just as bad as from frost -- the house is still moving. Is this just a normal thing in Texas? Do they build new houses with deeper footings to prevent this? Am I the only one who thought this was just not right?
