Porphyry stone - How to lay them

[adnama]

??? I have never used porphyry stone and am unsure how to deal with it.
My client wants to use it in the area of garden I have designed for her as she has had a porphyry sett path laid. At great and expense. She will not put me in touch with her supplier so I cannot ask them anything about it.

I have learnt that it comes in very random sizes from 200x?? to 600x?? That it should be laid "with the longer length across the eye". Causing all kinds of hassle as I can't just order the sizes I want for a random pattern as she appears to buy it by the ton which includes random sizes!

Next question is how to lay, do I specify a full mortar bed or spot mortar. Are there any other laying specs. I need?

Client has own builders, not landscapers but am told they can do anything as they build houses. However with respect I have been told that before to my cost so this time I am specifying EVERYTHING to cover myself.

Really need so advice please.

stone

is this what you mean??
sounds like the client is a bit snotty
to be honest sounds like you could be on a hiding to nothing mate.
when they start off like this it rarely has a happy ending.there seems to be a lot of stuff about its application as a cobble type stone but little about its use as a flag
mainly australian sites....
good luck let us know what happens

Thanks for the link although the paving stones are not the ones. they are very random in their thickness and size. The setts she used were from an Italian quarry, the poor guy laying them had a real job on his hands as they were not graded and were at least 100mm thick!

I have been reading up on laying stone that isn't 'dressed' and I understand that it makes using a full mortar bed difficult because of the varyign thicknesses of the stone is that so?

I much prefer the client to call me in before they have started work it makes my job much easier!
