Crushed Limestone vs Stone Dust

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.

Stone Dust

Stone dust is a finely crushed aggregate made up of stone particles smaller than 1/4 inch. It compacts tightly when installed and lightly moistened, creating a firm, smooth surface ideal for leveling and base preparation.

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

Stone Dust

• + Compacts very tightly
• + Creates a smooth, level surface
• + Affordable and widely available
• + Easy to shape and grade

• − Poor drainage
• − Can become muddy if overwatered
• − Dusty when dry
• − Erodes without edging

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.

Stone Dust

Fine crushed stone particles under 1/4 inch. Color varies by source rock and is typically gray or tan.
