Going to get someone to put a patio down for us in indian sandstone approx 30m2
Currently where it's going to go there are 3 huge concrete slabs approx 4mx2.5m and around 4-5 inches thick. These are solid so will take a bit of getting up so wondered if the indian sandstone can be laid on top or if it's advisable to take it all up and lay it on the revelant subase.
If it is ok to lay it on top of the concrete would you just need to put a sand and cement mix down to lay it on?
Thanks
