I'm thinking about building an attached garage on my house. The problem is that part of the garage will be over an area where I had demolished an old house with a small basement about five years ago.
My concern is the foundation of my new garage settling over this area with time. Even though it has had five years to settle, it will most assuredly settle some more yet, and any settling would unacceptable and problematic. So what are my options to avoid this?
Obviously one answer is to dig down to virgin soil and put a footing that deep.
Is it feasible to simply dig a trench with a backhoe down to virgin soil, and fill the trench with clean rock, and put the footing on top of that?
Drive some support posts down to virgin soil to support the footing?
Any thoughts on the matter would be appreciated.
TIA
