Having the sand layer too deep causes the sinking. We also had ours sprayed with a coating to repel oil. This should be done every couple of years or so. Get them to leave a few spare bricks just in case one breaks. If you brush soft sand into the gaps between the bricks every year they will not move laterally either. We have not had any weed issues yet, but if they do grow it will only be in sand so should be very easy to pull up. We had tarmac before and the block paving has transformed the front of the house.
Sodium chlorate will stop ALL weeds growing and only needs doing once a year.
