#9 Stone (#16 To #4, Washed)

#9 Washed Stone (#16 to #4 Size Range)

#9 washed stone in a #16 to #4 size range is a finely crushed, clean aggregate produced by washing natural stone to remove dust, clay, and other impurities. The washing process ensures a cleaner, more consistent product, making it ideal for applications where cleanliness and drainage are priorities.




The #16 to #4 size range means the particles are small-typically between 1/16" and 1/4"-which allows for excellent compaction while still promoting drainage. This makes #9 washed stone a popular choice for bedding under pavers, pipe bedding, and as a base for patios and walkways. It is also commonly used in concrete mixes and for backfilling around retaining walls. The washed attribute reduces dust, making it cleaner to handle and less likely to cause issues in finished surfaces or drainage systems. However, its small size means it is not ideal for load-bearing base layers or areas requiring significant structural support.
