Blue Quarry Rock – Premium Crushed Rock for Drainage, Base & Hardscape Projects

Blue Quarry Rock is a high-performance crushed basalt stone sourced from Northern California quarries, known for its durability, angular shape, and clean blue-gray color. Designed for both structural and decorative applications, this material compacts well (when fines are present) or drains efficiently (when clean), making it one of the most versatile aggregates for construction and landscaping projects across the Bay Area. Whether you’re building a driveway base, improving drainage, or creating a clean, modern landscape finish, Blue Quarry Rock delivers reliable performance and long-term stability.

Available Sizes & Specifications

Blue Quarry Basalt Rock is available in multiple sizes to match different project needs—from compactable base layers to free-draining aggregates and decorative finishes.

Compactable (With Fines)

• 3/4" Base Rock (Class II AB): Contains crushed rock + fines (dust) for superior compaction. Ideal for driveways, road base, paver base, and structural foundations.

• 1/4" Minus Quarry Fines: Fine, dusty material that compacts tightly. Best for pathways, stabilizing surfaces, and as a leveling layer under pavers or turf.

Drainage (Clean / No Fines)

• 1/4" Clean Chip: Small, clean crushed rock. Great for pipe bedding, shallow drainage, and decorative ground cover.

• 3/8" Clean Chip: Slightly larger than 1/4", offering improved drainage while still compacting lightly. Used for pathways, drainage zones, and utility backfill.

• 1/2" Drain Rock: Balanced size for French drains, trench drainage, and behind retaining walls.

• 3/4" Drain Rock (#57 Stone): Industry standard drainage rock. Ideal for drainage systems, driveways, and general construction use.

• 1.5" Drain Rock: Larger rock for heavy-duty drainage, erosion control, and high-flow water areas.

Oversized Options

• 1x4", 1x6", 2x4", 3x6", 4x8" Quarry Rock: Used for erosion control, slope stabilization, and structural backfill.

Pro Tip

• Use base rock (with fines) when you need compaction and stability.

• Use clean drain rock (no fines) when water flow and drainage are the priority.
