I have been offered some large (70cm) marble slabs at a very good price that have been reclaimed from an interior. I would like to use them for a new patio. What base should I use ? Could I lay them straight on to sand in case I wanted to move them at a later date?
Many thanks, love the site by the way!
They could be laid directly onto a sand bed, but they're probably best laid as any other patio flagstone - on a 10:1 mix of grit sand with cement. The cement content is low enough to prevent bonding between bed and base of flag, and there should be no staining problems.
