#6Aa Stone (3/8″ To 1″, Limestone)

#6Aa Stone (Limestone, 3/8” to 1”)

#6Aa stone in a 3/8” to 1” size range is a crushed limestone aggregate known for its durability and versatility. Produced by mechanically crushing and screening limestone, this material features angular edges that interlock well, providing excellent stability for a variety of construction applications.

The 3/8” to 1” size range offers a balanced blend of drainage and compaction. The smaller particles fill gaps between larger stones, making it suitable for use as a base material under driveways, walkways, and patios, while still allowing for effective water runoff. Its limestone composition ensures a strong, long-lasting foundation and a clean, uniform appearance.

#6Aa limestone is commonly used in both residential and commercial projects for road base, parking lots, drainage layers, and as a backfill material. Its angular shape resists shifting, but it may be less comfortable for barefoot traffic compared to rounded aggregates. Overall, this material is valued for its strength, drainage properties, and reliable performance in load-bearing and drainage-critical applications.
