The terminology used for soil support systems, unfortunately, is not completely consistent, so let's follow the American Concrete Institute's definitions, starting from the bottom: 1. Subgrade—this is the native soil (or improved soil), usually compacted 2. Subbase—this is a layer of gravel on top of the subgrade 3. Base …
