We had our driveway tarmacked last summer and within weeks it was showing minor signs of wear and tear (not sure if that says anything about the quality of the tarmac). It has since accumulated more surface damage.
We don't have a car at the moment and it's obvious from the tyre tracks that my next door neighbours are to blame. Their adjoining driveway is narrower than ours and they keep two cars parked on it, one behind the other. When they want to get the car at the back out, they simply swerve across our driveway and drive down it. It's the swerving that appears to be causing most of the damage.
We haven't actually told the neighbours not to drive on our driveway, because we're 95% sure they would ignore this and still drive down it when they thought we weren't looking. Parking on the street is only allowed between certain times.
I'd love to put up a fence between the drives, or bollards, but no one else on the estate has these and we're not sure it would even be allowed.
