Crushed for Performance. Refined for Aesthetic.
Gray Hills 3/8" Minus Crushed Pathway Fines is a finely crushed granite-based material designed for compacted pathways, walkways, patios, and ground cover. This versatile product blends 3/8" angular crushed rock with stone fines, creating a durable, lock-in-place surface that's both functional and visually refined.
 
With its light gray tone and consistent texture, this material is a go-to choice for residential, commercial, and municipal landscape projects across Marin, Napa, Sonoma, and Solano counties.

Frequently Asked Questions
Q: Does this material need to be compacted?
A: Yes. For best results, install in 2-inch layers, lightly moisten with water, and compact using a hand tamper or plate compactor. This improves durability and prevents shifting over time.
 
Q: Can I use this for driveways?
A: It’s suitable for light-use driveways, especially for walk-behind equipment or light vehicles. For regular vehicle traffic, we recommend a coarser base like Class 2 Road Base or 3/4" crushed rock beneath it.
 
Q: Will the fines create dust?
A: Yes, some dust is natural during dry handling or spreading. However, once installed and compacted, the fines help lock the material in place and settle with light moisture over time.
 
Q: How much area will one ton cover?
A: One ton covers approximately:
~ 110 sq ft at 2" depth
~ 55 sq ft at 4" depth
