I have a drag device that has spring teeth on the back. I can add cement blocks to get more depth. I find it good for leveling, soil and turning up weeds. For hard pan on the field, I would use a subsoiler to improve drainage and fertility of the soil. On driveways, drainage problems and a poorly made crown are the things that create the most headaches. I am expanding my driveway and will be using geogrid for the base and tile to improve the drainage of the clay soil. This should stabilize the driveway. and parking area. I have experienced the good and the bad in driveways, and the bad is a losing battle.
Sounds like you've got your hands full, Andrew! Thanks for giving us a rundown on some things that have worked for you. Talk to me about that poorly made crown. What are you doing to keep a bit of grade so you can shed the water? We work with a lot of folks who struggle to manage water on their drives and end up with season after season of potholes. Thanks for watching and reaching out! - Matt @ ABI
