The bathroom floor tiles have been paved, but how to remedy the flooding

Disassemble the floor drain or toilet, and poke a hole in the wall of the PVC sewer pipe, a little above the waterproof layer.

Knock it and re-apply the waterproof paint, and re-put it on.

Any remedy will leave a hidden danger, and there is no way to remedy it, but to knock on the repavement....

Inverted flooding is an interior decoration term, generally refers to the bathroom, kitchen and other rooms with water, in the case of the design of the drainage slope, due to the construction quality problems not only do not have the drainage slope to the floor drain, but there is a reverse slope - inverted flooding.

1. Cause analysis:

1) The floor of the balcony and bathroom should generally be 20 50mm lower than the indoor ground, but sometimes the drawings are designed to be as flat and the construction is negligent, resulting in the outflow of water from the ground.

2) Before construction, the ground elevation is leveled, the elastic line is not accurate, and the construction is not in accordance with the provisions of the flooding slope punching and scraping.

3) The floor drain in the bathroom is installed too high, resulting in the formation of water accumulation around the floor drain.

4) The civil construction and pipeline installation construction are not coordinated, or the pipeline direction is changed halfway, so that the floor drain position reserved during civil construction does not meet the installation requirements, and the pipeline is installed with another hole, resulting in the wrong direction of flooding.

Second, prevention and control measures:

1) The ground elevation design of the balcony and bathroom room should be 20 50mm lower than the indoor ground.

2) In the construction, first of all, the elevation of the floor base should be ensured accurately, and the floor drain should be radiated to the surrounding area before plastering, and the slope should be found and scraped flat with a scraper.

3) When the plumber installs the floor drain, he should pay attention to the accurate elevation, which is rather slightly lower than super high.

4) Strengthen the cooperation between civil construction and pipeline installation construction, control the change in the middle of construction, carefully carry out construction disclosure, and achieve a correct retention in place.

5) For the flooding toilet room, the surface layer should be chiseled off, the cement mortar surface layer should be re-smeared, and the flooding slope should be found.

6) When the ground elevation of the bathroom is the same as the indoor ground elevation, a cement mortar water barrier of 200mm wide and 30 50mm high can be made at the entrance of the bathroom room.

Heh, what else can this remedy?

I dismantled it and repasted it.
