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. >>>More
