1. Lower part of the waterproof layer: If the waterproof layer of the wall is aged, incorrect or improperly constructed, it may cause water penetration and cause water leakage problems.
2. Pipe leakage: If the water pipe in the wall leaks or the joint is loose, water may leak from the pipe to the inside of the wall, causing water seepage in the wall.
3. Poor sealing: The seals on the wall, such as the sealing ring at the bottom, the sealing strip of the toilet, etc., may cause water leakage if they are aged, used or installed improperly.
4. External wall penetration: If the waterproof layer connected to the outdoor is insufficient or there is a bottom, rainwater may penetrate into the indoor wall, causing water seepage problems.
5. Condensation: In a humid environment, condensation may form on the wall surface. If it is not drained in time, it may cause water seepage in the wall.
6. Ceiling water leakage: If there is a water leakage problem in the ceiling of the upper floor, water may seep into the wall below, causing indoor water seepage.
7. Gravity rise: If the gravity rises, the underground part of the wall may be subject to water penetration, causing water seepage problems.
8. External drainage problems: If the outdoor drainage system is not smooth or the drainage is poor, rainwater may accumulate on the walls, causing water seepage.
9. Rain leakage: Rainwater enters the room from windows, door cracks, etc., which may cause water seepage on the wall.
10. Paint or tiles on the walls: Paint on the walls, tiles, etc. on the walls may cause water to seep into the interior of the walls.
11. Aging materials: Wall materials such as paint, tiles, etc. may age over time, causing water leakage problems.
It is important to understand the root cause of water leaking problems so that appropriate steps can be taken for repair and prevention. If it is found that the wall is leaking, it is recommended to find out the cause of the leak in time and take appropriate repair measures to prevent further damage.
