Stone Dust vs Washed Gravel

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.

Washed Gravel

Washed gravel consists of crushed or rounded stone that has been mechanically washed to remove all fines and dust. Without fines, the stones do not compact, allowing water to flow freely between them. Washed gravel is commonly used where drainage is the primary concern.

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

Washed Gravel

• + Excellent drainage
• + No dust or mud
• + Does not retain water
• + Clean, uniform appearance

• − Does not compact
• − Can shift under load
• − Requires edging or containment
