Anonymous users2024-01-24The current situation is that 1, the ground waterproofing is not done to leak to the floor heating layer, 2, the concrete flanging height is not 200mm around the bathroom, 3, the waterproofing around the bathroom is not done, and the waterproofing around the bathroom pipe is not treated separately. 4. The door of the bathroom should be waterproof for 30 cm outward, and the current treatment method is to do waterproof several times on the ground. Especially at the root of the pipe, at the root of the flue.
The entrance position is waterproof first, and then a large area is waterproofed. As long as it doesn't leak under the screed.

Anonymous users2024-01-23The bathroom wall needs to be the most waterproof, generally 30cm on all sides, and 150cm-180cm on the shower.
If the downstairs does not say that the ceiling is leaking, this proves that the waterproofing is very successful, and it also indicates that there are signs of long-term leakage in the bathroom pipes, and there is saturated water in the middle of the ground above the floor. If there is no leakage downstairs, it will be diluted from the wall, and this phenomenon will occur, so it is advisable to find the leaking pipe as soon as possible and repair it.
There are two possibilities, one is that the waterproofing upstairs you said is not done well, and there is a little leakage. You can go upstairs and ask them to do a closed water test on their bathroom. The other is the aging of the water pipe (the water pipe and sewer pipe of the old house for the second decoration are the kind of cast iron) The pipe is rusted for a long time, if it is a long rust, do not remove the rust, or the external force touches the place, once the rust falls off, there will be a leakage. >>>More
Did the bathroom do a closed water test (24 hours) at that time? To determine whether it is due to water seepage caused by frequent bathing, for example, check that there is no gap in the corner of the bathroom wall and the joint between the sewer pipe and the floor. If there are no problems with the above questions, I suggest you go to a waterproof store to buy a waterproof material with water quality (I forgot the name, I only remember that after the material is sprayed on the surface of the red brick, the red brick can float on the water, the bottle is about 250 ml) You can spray it on the bathroom floor and in the corner of the wall. >>>More
It's seeping, and it's useless for you to glue Give up, unless the bathroom is all dismantled and redone.
WHEN THE DOOR STONE IS INSTALLED, IT SHOULD BE 5MM HIGHER THAN THE FLOOR TILE (DEPENDING ON THE SIZE OF THE BATHROOM FLOOR AND THE SIZE OF THE DRAINAGE SLOPE) TO MAKE A CHAMFER, COMMONLY KNOWN AS "WATER RETAINING PLATFORM". And when installing the door stone, the cement mortar to be pasted on the door stone must be prepared with a waterproofing agent. >>>More
