I'm laying Bradstone "Old Town" patio slabs. These are cement slabs made in moulds based on pieces of weathered and cart-worn limestone, so full of bumps, dishes and scours. They should look good when laid, but they are a pain to align and level, as a level taken from one part of the slabs is useless on another. The problem is not that the slabs are of uneven thickness which would simply require getting the amount of bedding right to align the tops, so much as it isn't obvious where the tops should be.
Does anyone have any tips about laying them, or similar ones.

i always use a line when laying slabs or flags,as we say "the line does not lie"
you just have to use your judgement to get the median top line of the flag near the string line
there is no magic its just a judgement call mate

if you screed the area with a sand and cement mix, using electrical conduit as a rail to screed off or even some thin timbers. Set up your screedrails to the correct falls and then tap down into the screeded mix, the flags generally come within a couple of milimetres of one another in depths so you should be able to get a good result using that method

the slabs are of uneven thickness ,so it wont work in this instance
like i say,its just skill and judgement,but a line helps

i have to agree with LLL. These slabs can vary wildy in thickness, from one corner to another. as is posted above, a line is better for these kind of slabs. Its all about your own preference in what you think is acceptable or not.
