So the gravel is compacted. But we need to mostly build up rather than remove. Only at the front of the driveway would need to be excavated - of course, otherwise we wouldn't be able to drive in right now. My daddy can operate an excavator quite well... But the material - I'm a bit afraid of that too. Without calculating exactly, I estimate about 2 trucks of gravel and the stones first! Mh. This will be tight here.
