Anonymous users2024-01-24The waterproofing of the bathroom is not well treated, and after the waterproof layer of the bathroom is done, the closed water test should be done for 48 hours, and after no leakage, the next step of construction is carried out.
It's because the excess water in the mortar layer under the floor tiles of the upstairs bathroom is basically dripping.
The waterproofing is not up to par, the wall should be 300 high, and the waterproofing should be done by professional people, and it is necessary to brush the bottom and surface many times.
Maybe the waterproofing upstairs is not done well, right? It could also be that there is a gap between the pipe upstairs and the ground that is not well sealed. In short, check it well, if it is not sealed well, it is very simple, seal it with sealant.
The floor of your bathroom is very waterproof, so the water does not leak directly into the downstairs bathroom, and the water seepage in the downstairs living room is because the water in your bathroom first seeps into the floor of your living room and then seeps into the downstairs living room. >>>More
It could be that your urinal and other sewer pipes are leaking, and you can only confirm it in detail by asking you to disassemble the ceiling downstairs!
