Does Gravel Wash Away?

Which Gravel Washes Away? Gravel can wash away during heavy rains, but proper installation and material selection greatly reduce this risk. Smaller, lighter gravel (like pea gravel) is more prone to washing than larger, heavier stone (like river rock or #57 gravel). Angular crushed stone interlocks and resists movement better than rounded stones. How to Prevent Washout To prevent gravel from washing away: Ensure proper grading so water flows where you want it — not across your gravel surface Install edging along all borders For driveways, create a crown (slight hump in the center) so water drains to the sides Slopes and Drainage On slopes, use crushed stone rather than rounded gravel, and consider installing a geogrid (honeycomb-shaped stabilizer) underneath. French drains or swales can redirect water before it reaches your gravel areas. If erosion is recurring, the underlying issue is usually poor drainage design rather than the gravel itself. Addressing water flow patterns is more effective than simply adding more gravel.

Topsoil

Fine, crumbly soil texture when screened. Dark brown to black color indicates high organic content. "Screened" topsoil has been run through a 3/8" or 1/2" screen to remove debris. Blended topsoil may include compost for extra nutrients.
