The Brew Cabin

Laying a york stone patio, on top of ols concrete path and newer concrete patio (50mm depth). However the curbstones which form the boundary of the patio only give me 80mm height to work with.
Question is do i go for 50mm flags with 30mm bed, or thinner flags and more bed....is there a problem with having the flags proud of the curb boundary by 10mm or so?
Advice gratefully received.

The bedding is the weakest material, so you should always aim to keep it to no more than 50mm thickness. Ideally, the bedding should be 30-50mm in thickness, so, given the choice, opt for slightly thicker flags.

Laying the flags 6-10mm higher than the top of the kerb is not a problem - that's how they should be laid, although 3-6mm upstand is much safer than a 10mm "trip".

thx for reply. much appreciated. I read in a post your not too well...hope things get sorted soon.
