We have to choose pavers to lay on plastic feet on top of waterproof membrane on a garage roof - What kind, size and thickness are suitable and what about future maintenance?

Have you contacted a structural engineer to make sure it will take the weight?

50mm slabs on a roof garden? Blimey that's some weight!

Agreed Dave, hence the need for a S E.

Thank you for suggestions but the (underground) garage roof is newly built with block and beam and designed to be paved - Just don't know what strength and thickness to choose of pavers resting on feet and about the problem of maintenance - dirt/moss collecting underneath pavers and blocking drain

if its block and beam why cant you just pave straight on top on a 35-50mm bedding layer
I have seen a job in luton done like this recently and they just paved straight on top,no need for feet

paving feet (small plastic spacers/supports) are used to support 2x2 greys on commercial roofs at plant deck areas.

Definately if it can take the weight then you should pave it normally. Those chair systems look awful with the large gaps and sound and feel terrible to walk on. It'll also be easier to maintain over the years and there's less waterproofing required.

they are normally for industrial buildings and surrounded in stone
