I have a driveway and was wondering if this would be a suitable way to get a sturdy paver stone foundation. I know its not the preferred or right way to do it, but was hoping it would be close in durability. I live in Louisiana so the original driveway slab has sunken about a foot or so below the house and carport. So I ordered some tough dirt/clay/rock mixture to fill all around the house an over the old driveway. Let me know if this is a bad idea and list some reasons why this would fail or if you think this had a good chance at lasting.
