ᐅ Embedding HT pipes in masonry: How are these secured within the wall?

MokkaHello everyone,
I have a question regarding PVC waste pipes inside walls:
If PVC waste pipes are installed directly within the wall (without boxing in or cladding), how should they be properly secured? Is it still possible to use pipe clamps? Are they fixed with mortar? I have sometimes seen polyurethane foam used—is that allowed?
For soundproofing, the pipes are covered with insulation sleeves. Are any additional measures necessary when embedding them in masonry?
Thank you very much for your help!!

HT pipes embedded in the wall are almost always structurally problematic. In new construction (where this issue has been accounted for!), I have seen special U-blocks designed for this purpose, which apparently provide enough space to accommodate the pipe along with its clamp.
Embedding the pipe in concrete or similar is, in my opinion, a very bad idea for sound insulation reasons. In that case, you might as well skip upgrades like insulation sleeves, as they won’t make a difference.
Why not just box it in? A typical HT pipe usually doesn’t require more than about 10cm x 10cm (4 inches x 4 inches) of space. If needed, you could combine it with a built-in unit (drywall or aerated concrete block) such as a shelf or similar.
