Our driveway is covered in pea gravel, which hides a drain cover.
Don't ever make the mistake that I did, and try manoeuvring your van over it to create space for another vehicle. There was an almighty bang, and the van lurched. I thought I had hit the house at first, then looked at the offside front wheel, and realised my problem - it had dropped about 6 inches into the hole left by a cracked cast iron drain cover (probably original to the house so at least 60 years old).
The only reason the van had not dropped the wheel fully into the hole was because there was a piece of tough fabric over the top of the drain cover, to stop the stones sliding everywhere, and this was somehow holding things up. We managed to push and gently reverse the van back off the cover/hole (aren't neighbours great), but the van was now stranded, as it couldn't go any further back (small drive), and had to go forward over the drain. Lots of bits of wood later, I tentatively drove the van over the temporary drain cover, and got it out.
We now have a new drain cover rated at 5 tonnes, but I don't put a car or van anywhere near it.
Back to the OP question - I think you will need to get the drive re-laid to sort it properly.
