The client had old sandstone boulders making up the edging around her garden beds. They looked okay, but they were falling apart were not going to last much longer. So we removed all the old sandstone and replaced them with Rundle stackable boulders. Not only is the colour much better, these stones are not brittle and won't fall apart. We also added 40mm Rundle to the beds to tie all the colours together and to make an excellent look!
