I want to lay sandstone slabs on top of existing concrete slabs. Is this advisable - I've heard there can be drainage issues - and should the existing concrete slabs be scarified for better adhesion of the mortar? It's a small area - 7ft x 8ft - and I thought I would just use a builders sand-cement mortar. Will this work???
Ah! I've just found the relevant page on the site that deals pretty much with this issue, although any helpful suggestions still gatefully received!
