#89 Stone vs Rip Rap

#89 Stone

Small angular crushed stone approximately 3/8 inch and smaller. Similar in size to pea gravel but with angular edges that provide better compaction and stability. A versatile fine aggregate used in both construction and landscaping applications.

Rip Rap

Large, heavy, angular stones ranging from 6 to 24+ inches used primarily for erosion control. Rip rap protects shorelines, stream banks, bridge abutments, and steep slopes from water erosion. The heavy weight and interlocking shape resist displacement by flowing water and wave action.

#89 Stone

• + Angular edges compact better than rounded pea gravel
• + Small size fills tight spaces
• + Good for pipe bedding and utility trenches
• + Comfortable enough for walkways
• + Excellent drainage

• − Too small for driveway base layers
• − Can migrate without edging

• − May be tracked by shoes
• − Not widely stocked at all suppliers

Rip Rap

• + Extremely effective at preventing water erosion
• + Heavy weight resists displacement by water
• + Long-lasting — lasts decades with no maintenance
• + Angular shape interlocks for stability
• + Natural appearance blends with waterside environments

• − Very heavy — requires heavy equipment to place
• − Expensive for large projects
• − Not suitable for foot traffic
• − Requires engineering design for major installations
• − Limited decorative appeal

#89 Stone

Angular crushed stone pieces 3/8" and smaller. Color varies by quarry — typically gray, blue-gray, or tan. The angular shape distinguishes it from similarly-sized pea gravel.

Rip Rap

Large angular stones typically 6-24 inches in diameter, though some applications use stones up to 36 inches or larger. Weight ranges from 25 to 500+ pounds per stone. Colors vary by source quarry — typically gray, blue-gray, tan, or brown. Sold by the ton rather than by the yard.
