The reason of damp dormitory floor.

There may be many reasons why the dormitory floor is wet, and there are the following possibilities:

1. Wet weather: If the dormitory is in wet weather, such as rainy day or rainy season, the humidity in the dormitory will increase, resulting in wet dormitory floor.

2. Poor ventilation: If the ventilation system in the dormitory is not smooth and the air cannot circulate, moisture will stay in the dormitory, resulting in wet floor.

3. Insufficient water-resisting layer: In some dormitories that have been in disrepair for a long time or newly built dormitories, the design of water-resisting layer is unreasonable, and there is no suitable gap between the floor and cement, so water will penetrate into the floor, resulting in the floor being wet.

4. The floor of the room is higher than the outer floor of the dormitory: if the floor of the dormitory is higher than the outer floor, the floor of the dormitory will sometimes be wet because of the downward flow of water.

5. Water pipes or rainwater pipes: If there is a problem with the water pipes or rainwater pipes in the dormitory, such as water leakage or rupture, it will cause water to leak to the ground and cause the floor to be wet.

In short, many factors may cause the dormitory floor to be wet, so we need to find the problems in time and take measures to keep the dormitory dry to prevent adverse effects on our health.
