Paving stones settle after one year (Carport track rut)

No, that will never work, the rut is way too deep for that. And strangely, it’s only on one side... well, those few stones they’ll still be able to get out, 3 hours of work :)

3 hours of work, no way. It starts with travel time there and back. Then somehow pulling the stones out of there. It’s not enough to just fix the rut, but 20-30cm to the left and right should come out as well. Minimum the width of the compactor. Do you have gravel or sand? With gravel, it tends to continuously crumble and it takes a while to find a suitable spot where no fist-sized hole forms. He will either have to remove all the gravel and then add recycled material again or simply fill up with gravel and then compact the paved area. In my experience, it will then be more uneven than before... though I’m quite an amateur. I assume it wasn’t properly compacted. You’re supposed to compact in layers... but often this is not done very precisely to save some time.

Yes, you're right, it will probably be more like one day's work. Would you accept that or not?

Presumably, it was done exactly the same way as with some in our settlement. The dirt is scraped off a bit, 20cm of mineral is dumped on, and then it's paved.

would definitely insist on corrections.

I am generally not a fan of cobblestones on gravel because I have seen many installations that have settled in some spots after a few years, and not just on the driveway. Back then, we concreted a 1.5m access path in front of the house and later laid cobblestones on top. These are still unchanged today. Next to it, large areas of cobblestones were later laid on gravel, directly on natural ground and at most compacted with a plate compactor, etc. After a few years, you could clearly see the edge where the concrete strip is; on both sides it had slightly given way, without any load at all. No matter how much you compact, if it is not truly natural ground, there is always a risk under such stress. Therefore, I am almost certain that ruts will eventually return there, even if it is repaired now.

Split is generally not a problem at all. The base must fit, then 3-4cm of split, then paving.

Unfortunately, people often skimp on this and then compact with such a ridiculous garden compactor. That simply doesn't work.

If installed correctly, this should not happen. Proper subsoil, (Geotextiel) frost protection gravel and paving. Construct at least 1 cm higher and then compact to the final height with the vibrating plate.
