The bathroom is waterproof, leaking, seeping

The reason why the bathroom seeped water downstairs.

Answer: When the water leaks downstairs, the first thing you can be sure of is that the original waterproof layer of the ground is damaged somewhere, otherwise no matter how much water leaks downstairs, it will not leak downstairs. It can only seep into your tiled surface, or into other rooms of your own home.

Theoretically, as long as the waterproof layer is damaged somewhere, the open water in the bathroom penetrates below the tile surface from the corner, tile surface and joints or any other possible place, and concentrates on the mortar layer, then the mortar layer is equivalent to becoming a water layer, and then concentrates on the waterproof layer to leak downstairs.

Conclusion: The vast majority of the water leakage to the downstairs, the treatment point is useless, the whole surface has to be treated, only to ensure that the entire ground is completely free of water can penetrate into the mortar layer below the surface of the tile, there will be no water seepage to the damage of the waterproof layer, so that the problem of water leakage is solved.
