Anonymous users2024-01-24How to make waterproofing on fillers? This is the first time I've heard of such a practice.
Waterproofing is generally done directly on the structural layer, first the structure is inspected and tested, if the structure is not leaking, it is leveled, and waterproofing can be done after completion.
Waterproofing the filling will make the waterproof layer unstable, and there is no guarantee that there will be no leakage under the filling, which is a great hidden danger.
Your waterproofing may have to be redone.

You should ask a professional renovation construction master, who can tell you the sunken bathroom, with wooden planks as the bottom and cement steel bars on top, can this question be?
