The downstairs bathroom of the resident of my house leaked, and I smashed open the bathroom floor to

Bathrooms are basically caisson structure, composed of concrete structure, waterproof layer, backfill, waterproof layer, ceramic tiles, once the waterproof layer is damaged, the water has fluidity, it will penetrate downstairs through the concrete, resulting in damage to the interior decoration, causing problems such as wall peeling, wrapping and peeling.

Early detection and early treatment of water leakage problems in neighbors, find the source of leakage, focus on strengthening the treatment of leakage parts, and it is best to find a professional waterproof unit to inspect and give corresponding plans.

The downstairs residents' bathroom is restored, and it must be waterproofed and then backfilled and tiled, I hope it can help you.

There is a lot of water on the floor tiles after the bathroom leaks and smashes open, indicating that the leakage point of the waterproof layer is at a slightly higher position.

There is a complete waterproof layer on the floor and under the floor tiles of the bathroom. When water seeps under the floor tiles and above the waterproof layer, the water should flow from high to low in the gap between the sand and plaster. Leakage occurs when a waterproof bad spot occurs, and in a slightly lower place, water that cannot leak to the bottom is preserved, resulting in stagnant water.

Methods for dealing with water infiltration:

1. First remove the sand and ash layer of floor tiles and paste bricks;

2. Redo the sand and gray surface leveling;

3. Use polypropylene cloth as a waterproof layer;

4. After the cement is dry, do a closed water test, and then paste the tile after making sure that there is no water leakage.
