Best type of Rock for Parking Lot?
Hello BP!
I am working on developing some land I have into Boat/RV parking.
That being said....
1) What type of rock did you use?
2) How was the lot layered?
3) Did you do anything to prevent weeds in the future?
I was considering crushed concrete but I'm not sure if that will be the best choice.

Depends on your soil type
Hill country rock just grade.
Black soil or sand.
3 inch clean rock or recycled concrete. 4 inches for base. Wait till it rains then drive something heavy to pack it in. Then 4 inches or 1 1/2 inch with the fines for the roads. For the parking I would just use the 3 inch clean.
Really recommend you use the engineer geogrid fabric for roads. The lay 4 inches of 1 1/2 inch with the fines. Must be 1 1/2 or larger to work. Smaller or pea gravel will work thru the mesh. No potholes ever. Don’t grade to deep though.
You will get weeds even in rock. Mix both the 1 year pre emergent and the All kill and spray together. If you’re spraying and it is not dying you have water hemp. Ask for a spray with strength 10 to 14 on the label and spray higher mix.
