If you dig beneath the top layer of earth, you’ll find the dirt that’s used for fill (AKA: fill dirt). Here, dirt does not contain any type of organic matter. Instead, it’s purely comprised of broken down rocks, clay and sand. But why would you want that?
The main reason is stability. When dirt contains organic matter, it becomes prone to shifting and settling over time. Fill dirt, on the other hand, is without void spaces and won’t shift or move. This makes it a perfect place filler.
