Driveway Double Hardcore

[nichollsjames]

Can I compact hardcore on top of existing hardcore?

About 6 years ago we had our drive hardcore, 30s semi about 14x6m.
The area furthest from the house has dipped and we have a pond in wet weather. I dug a channel to a trench and backfilled with gravel to alleviate somewhat, however I intend to edge and gravel the driveway to tidy it up a little.

Yes, assuming you mean scalpings/mot type 1/2 etc.
And the surface is quite clean, no point putting good stone over mud
