#8 Gravel vs Rip Rap

#8 Gravel

Small crushed stone approximately 3/8 to 1/2 inch in size. Good for walkways and as a top dressing for driveways. #8 gravel bridges the gap between coarse aggregates and fine pea gravel, offering a balance of comfort and stability.

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.

#8 Gravel

• ✓ Walkways
• ✓ Patios
• ✓ Between pavers
• ✓ Asphalt mix
• ✓ Top dressing
• ✓ Drainage backfill

Rip Rap

• ✓ Shoreline protection
• ✓ Stream bank stabilization
• ✓ Bridge abutments
• ✓ Steep slope stabilization
• ✓ Culvert outlets
• ✓ Retaining wall faces

#8 Gravel

• + Smaller size is more comfortable to walk on
• + Compacts better than larger stone
• + Good for filling gaps between pavers
• + Excellent drainage
• + Smooth driveway top-dressing

• − Can migrate without edging
• − Not as stable as larger crushed stone
• − May be tracked by shoes
• − Less commonly stocked than #57
• − Dusty when dry

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

#8 Gravel

#8 gravel consists of angular crushed stone pieces from 3/8" to 1/2" in diameter. Like other crushed stone, color varies by source quarry — gray, blue-gray, tan, and brown are most common.

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.
