We have had our yard "done". One bloke (Dushty-Sean the Mini Digger driver), 20 tonne of this mixed-sized aggregate 804 gravel with bits from small to 'dusht' in it and about half a day.
In addition, some of the stones we have saved, and some of the big bits originally 'chucked' over the wall by 804-Pete when he first cleared away the boggy turf, we decided might be quite attractive used back in the garden. We were thinking just of groups or small rings around plants almost as 'mulch' but one of these was so huge Dad couldn't lift it. Mum and Dad dragged it into the yard on a 1-tonne builder bag and Mum decided it needed to be stood on end like a mini henge. We all think it looks rather good there!
