What is clean fill dirt? (2)Backfill soil is the material used to fill holes and low areas or to build terrain in construction sites.Underground, located 12″ below, is called filler dirt. It consists of partially broken soil containing clay, sand, silt and stones, and any other material found in the original soil. If the fill soil comes from the subsoil of former farmland or forest, it will contain whatever material is there. It may contain some organic material, but desirable filler soil is primarily inorganic. Its inorganic qualities make it ideal as a landfill because it does not break down or settle as organic soils often do.

Fill soil is generally less expensive than topsoil or other types of soil needed to support landscape plants. For example, you need certain types of highly organic soil for gardening, depending on what you want to grow. However, to build a house or roadbed, you cannot use topsoil or other garden soil because the organic materials will decompose and the surface will sink. This soil also erodes quickly and does not support building structures.For construction projects, you should use heavier, rockier inorganic fill soil..

Where does the filler dirt come from?

Fill soil is most often used to change the grade or elevation of a property to make it more ideal for its intended use. Fill soil is known as subsoil because it is removed from under the top layer of soil. Depending on where the dirt is collected, it is usually about six inches below the ground. The removal of dirt from this bottom is intentional because it does not contain organic matter. Organic matter breaks down over time, and in doing so, it enriches the soil with many nutrients to help support plant life. However, this organic matter is what also makes the soil very unstable. As the organic matter decomposes, the surrounding soil begins to shift, so the topsoil cannot be used for construction. Filling in soil that is lacking in organic matter is what makes it a terrible soil choice if you want to start a garden.
