Macon, IL | I have 2 driveways-both built on formerly farmground, first one was just clear 5" of dirt and dumped in CA6. Had to bring in CA6 every spring for next 7 years before it was finally stable.
2nd one I cleared about 3" and put down geo fabric and dumped rock on-have never had to add anything to it.
If I were doing it again and could afford it I would remove 4" of soil, put down fabric, cover with 4-6" of 3" rock, then put CA6 over the top of that. The driveway would be a little above grade so drain well, and with that 3" would be room below. You may have to add some CA6 2nd year but bet you never would again. | |

Building a driveway on geotextile fabric...what gravel?
