I broke old slabs and used them as a wall/feature, they really need to be dipping for the best effect, if you can see the top surface or side surface then it losses the effect. They also need to be of the same thickness.
small front garden many years ago..
back garden, you have to look carefully to spot the wall, ignore the soapsud foam that my naughty child introduced to the waterfall..
