Upstairs people in the bathroom punching holes with styrofoam sealing, is it useful

I have been doing decoration for more than 10 years, and there are many owners who want to change the location of the toilet, but downstairs unless it is their relatives and friends, they will not agree, and the property must agree to re-punch the hole in the floor, but if there is a waterproof problem in their own construction, it will be very troublesome, and it is very difficult to do if the pipe installation is leaking. Feng Shui is still secondary, because the bathroom is not a place where people stay for a long time, and it will not affect people too much. But from the perspective of safe use, it is better to disagree. >>>More

It should be a slight leakage, temporarily blocked by dirt, and the leakage has been reduced a lot, but it is a hidden danger after all; It is necessary to observe at any time, and if there are water marks, you must ask the upstairs to repair the local waterproof layer.

That's easy to do, now there are not so many things for the people on TV. Finding a reporter to blow up the light and coordinate it will be more effective than if you go to the root and say it.

The waterproofing of the large area above is fine, the key lies in the perimeter of each sewer pipe, and the waterproof material does not return when doing waterproofing, resulting in seepage points around the pipe.
