This question is relevant for apartments in new buildings, where renovation work has not yet begun. Noise from pipes in a riser disturbs everyone. The pipes in the sewer risers of such apartments are usually bare and the risers themselves are open. Be sure to make sure that before closing the risers, the pipes are wrapped in soundproofing material. The experts themselves know what material to use for this. You can, for example, use rolls of foamed rubber or glass wool with foil. And do not forget that, unfortunately, in our Georgian reality, you always need to be prepared for the fact that the riser can be a source of water and moisture leakage. Therefore, it is advisable to use a waterproof material so that it retains its properties longer.
