Please dont jump me for being an amateur, but my very best lawn care/ mulch/ whimsical landscape customer now needs her driveway fixed because she just bought a new BMW, and the potholes drive her nuts. Ive got a 5 X 8 heavy duty landscape trailer. She has a quarter mile long dirt driveway with some potholes and washouts. Shed like a price on fixing her driveway, but when I talked to her she didnt know exactly what she meant by fixed. So now, Im the professional, and I should be able to help her understand what she needs. I make roughly 25% of my revenue from this lady and stand to make some more gravy, but this isnt something Ive worked with other than what a foreman ordered me to do. She has a dirt driveway, and Ive found more ½ inch stone than anything else that youd find in a stockyard but not an overwhelming amount. The driveway cant be more than 3-5 years old. Should I fill in the potholes with shale or ½ stone? Again, this is not my area of expertise, so I dont know what sort of stone went into the driveway, but it seems like a shaley, gravely sort of grey mix. What should I suggest?
