Fill: Material such as dirt, gravel, or coal ash used to build up an area of land. Flowable Fill: A fill material that flows like a liquid, is selfleveling, requires no com paction or vibration to achieve maximum density, hardens to a predetermined strength, and is sometimes used as a controlled lowstrength material.
