Why Two Layers Work Better Than One
Base layer (#411) creates the foundation
Angular crushed stone with fine particles ("fines") compacts into a dense, stable mass. Think of it like concrete without the water. Without a proper base, your driveway will develop ruts and soft spots within the first year.
Surface layer (#57) provides the driving experience
3/4-inch clean crushed stone looks attractive, drains well, and provides good traction. It doesn't compact like base material, which means it stays loose enough to drive on comfortably without punishing your vehicle suspension.
Landscape fabric between fabric and native soil
Prevents gravel from sinking into soil over time and stops weeds from growing up through. Use 4–6 oz woven geotextile for driveways with vehicle traffic.
What NOT to Use on Driveways
- ✗Pea gravel as only layer: Round stones don't compact. They roll under tires, migrate to lawn edges, and create an unstable surface. Fine for decoration, terrible for driveways.
- ✗River rock: Too large and round. Same migration problems as pea gravel, but heavier. Beautiful in landscape beds, dangerous on driveways.
- ✗Sand: Washes away in rain and provides no structural stability. Never use sand as a driveway material.
- ✗Fine sand or stone dust only: Without coarser aggregate mixed in, fine material becomes muddy when wet and compacts into a hard crust when dry.
