The whole house rests on the foundation or it will sink. What does the foundation rest on? Why doesn’t the foundation sink just as easily?

Question

I get that some foundations do have sinking issues, but how does having a foundation help? If the foundation is poured and solidifies, what stops the weight of the house from immediately sinking/tilting the foundation?

Answer 1

The foundation of most houses rests on what’s called a “footer”, which is concrete poured about 2 to 3 feet wide, around the rectangular area of a houses frame, which is then leveled, and allowed to dry, then bricklayers build the cement block foundation on that.

This “footer” goes unseen, because it’s about 2 to 12 feet underground, and you’ll usually never see it.
