Crushed Limestone vs Rip Rap

Crushed Limestone

Crushed sedimentary rock with a pale gray to white color. Compacts well and provides good drainage. Limestone is a popular choice in the Midwest and South where it's quarried locally, keeping costs low.

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.

Crushed Limestone

• ✓ Driveways
• ✓ Pathways
• ✓ Base material
• ✓ Garden beds
• ✓ Parking pads
• ✓ Erosion control

Rip Rap

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

Crushed Limestone

• + Compacts into a firm, stable surface
• + Light color brightens landscapes
• + Good drainage properties
• + Affordable in limestone-rich regions
• + Natural weed suppression when compacted

• − Can become muddy when wet (stone dust)
• − Limited color options
• − May raise soil pH over time
• − Dusty in dry conditions
• − Not available everywhere

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

Crushed Limestone

Available from fine limestone screenings up to 3-inch chunks. Most common sizes are 3/4" and 1.5". Color ranges from pale gray to off-white, sometimes with a slight yellow tint. Compacted limestone screenings create a smooth, almost concrete-like surface.

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.
