Patio on balcony

I have a balcony at the rear of my house on which i would like to lay textured paving slabs. The balcony is constructed from approx. 8" conrete and part of it forms the roof of my garage and workshop. The previous covering of slabs was in poor condition and allowed water to penetrate into the rooms below. I sealed the concrete with Aquaseal 8 months ago and this has cured all water penetration. Is it now possible to lay slabs onto this base or is this not advisable from a water-proofing point of view. Any advise would be gratefully appreciated.

Normally, balconies and roof gardens are paved with what are known as Promenade Pavers, a type of lightweight flags, but, as your balcony is a fairly substantial concrete construction, you could use any flags you choose.
Now that you've Aqua-sealed the surface, I would suggest that you lay a damp proof membrane over the concrete (Visqueen 1200 or similar), then lay the flags on a full bed of Class II mortar, with mortared joints, and adequate fall to a drainage point. That should be fine. :)
