For you people in the colder areas. Anybody have homes with shallow foundations? If so how do you stop the frost from heaving your house? I own a house with the foundation a little over 2 ft below grade. The frost in Ontario can go 3-4ft deep some years. I have a closed in porch at the entry which heaves a little. It throws the whole house out of whack. Paneling buckels, doors don't close right, etc. I can not remove the porch, it is part of the house, and I don't know if that corner of the house is to blame, I just think it it the porch. Any ideas?
