Evergrande City Hardcover Room My floor is black. What happened?

The main problem may be your bathroom or geothermal.

Toilet reason:

1, the laying angle of indoor floor tiles in the bathroom is not enough, which causes the floor water to flow outside when you take a bath or wash clothes with water. But according to the schematic diagram you provided. This possibility is relatively small, because most of these reasons are that the bathroom door turns black first.

2. Dew point appears in bathroom waterproofing. There will be many problems in bathroom waterproofing due to construction reasons, especially in hardcover rooms. In order to catch up with the construction period, many builders put tiles in the bathroom immediately after waterproofing in a hurry or without doing water-closing experiments at all. So sometimes water flows to the living room with dew point.

Look at the schematic diagram you marked. There are many problems in your family. It's really troublesome to find a problem like this.

If you want to know whether the geothermal energy leaks, the simplest thing is to test the pressure of your geothermal energy, if the pressure is normal. The possibility of geothermal leakage is ruled out.

If the leakage of geothermal pipeline is eliminated, it will be well solved. The problem must be above the bathroom. Because most of the black areas on your floor are near the bathroom.

Water will flow to all parts of the room near the bathroom with the dew point, because there is a concrete floor under your floor, and there will be cracks in it or on the surface, and water will flow everywhere with the cracks. In addition, because it is geothermal, the water itself will evaporate, penetrate into your floor and be blackened.

If the waterproof problem of the bathroom is not solved, the new floor will still turn black in the future.

Supplement: If the floor itself is wet, it will not dry or even have bugs for two years.

Now many hardcover rooms, the project is really rough. Like the Old Green Community near Evergrande City, the problem there is more serious.
