Hi all, I'm hoping to have my patio laid soon, I've got black limestone flags (Black Kadapha from Pavestone) they're only 600x300 so pretty small and I read on this website that usually thinner stuff is more like a tile than a flag..
I thought they would be good on a regular base of hardcore wacked down and then quite a moist mix of sand & cement like most the other advice on here... my dad thinks it will be a better job and last longer if we first put in a concrete base and then lay them on top with a thinnish very wet mix.. more like mortar to make sure they stick and won't come loose. I suppose it's more like laying slate flags inside a house on concrete floor. He says because they are so small I might have more issues with movement/ sinking etc and wants it to be properly done and last for many years etc.
Just want to know from anyone who's installed such things is a concrete base the best way to do it or is it overkill?
Any advice greatly appreciated!
