Fill Material (2.5″ Minus, Crushed, Non-Spec)

Fill material in a 2.5" minus size range, featuring a crushed, non-spec attribute, is a versatile aggregate commonly used in construction and landscaping. This material consists of a blend of stone fragments and fines, all sized at 2.5 inches and smaller. The "crushed" aspect means the aggregate has angular edges, which help it compact well, while "non-spec" indicates it does not meet strict grading or certification standards, making it suitable for general fill rather than structural or engineered applications.
