I have a well-compacted gravel driveway (15+years) in need of new gravel. Have square meterage but am at a bit of a loss as to what was originally laid depth-wise as top layer (apart from being pea gravel). Obviously this affects the cost and we're talking of ~ 410m2.
Similarly I wonder whether to consider split gravel to aid binding better since driveway gets constant traffic for three houses..?
Any learned advice on these would be very much appreciated - I searched the Projects but there is no mention of typical gravel depths for such a re-surfacing project.
