re: Can I pour my concrete patio floor directly over dirt?

Most slabs are poured over dirt with a couple inches of compacted sand to insure a uniform thickness throughout.
Typically the dirt is excavated a few inches below grade, then place sand, rake it even just a bit above grade then wet it so it compacts to grade.
Concrete over just dirt will have many hills and valleys.
