How to deal with water seepage in the bathroom and how to repair it

Where does the water seepage come from in the corner of the outside of the bathroom or at the door of the bathroom? Which way should it be governed?

Answer: Many users may have a misunderstanding, that the waterproof layer will only leak downstairs if there is a problem, in fact, it is not the case, the waterproof layer is divided into a horizontal waterproof layer and a vertical waterproof layer on the side, the horizontal waterproof layer leaks to the downstairs if there is a problem, and the vertical waterproof layer on the side leaks to their own home if there is a problem. Water leaking into the corner of the outside of your bathroom or the bathroom door is first sure that the vertical waterproof layer on the side is broken somewhere, otherwise no matter how much water can only come up from your tile surface.

In fact, the damp marks we see in the corner of the bathroom or the door of the bathroom are not vertically leaked in the past, theoretically speaking, 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 is concentrated in the mortar layer, then the mortar layer is equivalent to becoming a water layer, and then concentrated in the waterproof layer where the damage leaks downstairs.

Note: The damp and mildew of about 50 cm from the ground to the outside wall of the bathroom is caused by water seepage on the bathroom floor, not the wall water seepage. Many unprofessional people will definitely not be able to solve the problem by simply repairing the wall.

Conclusion: The vast majority of the bathroom leaks to their own home, it is useless to treat the whole surface, 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 seeping into the damage of the waterproof layer, so that the problem of water leakage is solved.
