#8 Stone (#8 To 3/8″, Ca8)

#8 Stone (Ca8) in a #8 to 3/8” Size Range

#8 stone with a Ca8 attribute in a #8 to 3/8" size range is a crushed aggregate commonly produced from limestone or gravel. The Ca8 designation indicates that the material meets specific gradation and quality standards, ensuring consistency and reliability for construction applications. The small, angular particles in this size range provide excellent interlock and stability.




This particular size and gradation make #8 stone ideal for use as a top layer in driveways, walkways, and patios, as well as for bedding pipes and drainage systems. Its compactable nature allows for a stable surface, while the angular shape enhances load-bearing capacity and reduces shifting. The fine size also makes it suitable for mixing into concrete or asphalt. One advantage of this material is its balance between drainage and compaction-small enough to lock together, yet large enough to allow water to pass through, minimizing pooling and erosion. However, it may not be suitable for areas requiring a very smooth finish or for decorative landscaping where larger or more colorful stones are preferred.
