Hello everyone,
how is the waterproofing of a parapet usually done when a railing is to be installed on it? I started drawing it as follows:
On top of the Ytong block, there would probably be a concrete edging (which should be about 10 or 15 cm (4 or 6 inches) high) to mount the railing. How is the waterproofing normally done here? Would you drill into the metal later (unless you use a granite slab with a slight slope inward instead of metal)?

Info: I spoke with two waterproofing specialists today. One applies the vapor barrier only on the side of the aerated concrete block (Ytong). A concrete beam is planned on top of the aerated concrete block. The second specialist would apply the vapor barrier on the concrete beam.
Regarding the railing, there are also different opinions. The first specialist says that a railing on the parapet (attic) is not a problem. He mentioned there are special (I believe plastic) sealings for fastening the railing. The second specialist strongly advises against this (a side-mounted railing would be the safest option).
What is your opinion on railings and waterproofing directly on the parapet?
