The bathroom at home was waterproofed, but it seeped into the wall of the neighbor s house next door

If the water leaks in the bath, it must be that the wall waterproofing is not done well, and it has nothing to do with the water, that is, the bath water seeps into the brick joint and then to the next door, and more information is needed!

I don't know if you care about it when you brush the waterproof at home, this situation should be waterproof only brushed on the ground, and the four sides of the wall must be brushed 10 cm. Therefore, the current water leakage in your home will be in the place where there is no waterproofing above the baseboard, and the tiles and walls are not waterproof, so they will seep through the joints of the tiles.

If you want to completely solve the problem, you can only peel off the leaky wall and repaint the waterproof and then reinstall the tiles, but the problem is that if you remove a tile, you may have to remove it all in one circle. If the next door doesn't care, then it can only be used.

However, it should be noted in the future that even if you do not paint the walls and floors according to the regulations, you should at least brush the places where there are showers and baths that will often splash with water, and the other four sides should be brushed at least 40-50 cm high from the ground.

I guess it's a wall.

Gaps between tiles. Sometimes you can also see traces of water on the tiles. Inside the walls are cement and bricks. It will absorb water, and if you absorb too much, it will seep through.

It doesn't matter, it's not a big deal, as long as it doesn't leak downstairs.
