Crusher Run vs Rip Rap

Crusher Run

Dense blend of crushed stone and stone dust ranging from 1.5" down to fine particles. The fines fill voids between larger stones, creating a surface that self-compacts into an exceptionally firm, stable base. Crusher run is the most popular single-material solution for driveways and parking areas.

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.

Crusher Run

• ✓ Driveways
• ✓ Parking areas
• ✓ Road base
• ✓ Foundation sub-base
• ✓ Backfill
• ✓ Equipment pads

Rip Rap

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

Crusher Run

• + Self-compacts into an extremely stable surface
• + Single-layer application (no need for multiple grades)
• + Excellent load-bearing capacity
• + Affordable and widely available
• + Fines lock stones together to resist shifting

• − Not decorative — utilitarian gray appearance
• − Can become muddy if drainage is poor
• − Dusty in dry conditions
• − Tracks onto paved surfaces
• − Requires compaction equipment for best results

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

Crusher Run

Mix of angular crushed stone from 1.5" down to fine stone dust. The blend of sizes is what makes it self-compacting. Color is typically gray or blue-gray depending on source rock. Sometimes called "crusher run" because it's the raw output of a stone crusher.

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.
