The wall is bleeding and leaking, causing mildew and powder on the wall. There are many reasons for water leakage in the wall, and it is troublesome to remedy it. The important thing is to find out the cause and find the right remedy. There are generally four situations as follows.

1. The concealed pipe of the water supply pipe is not installed properly, the water pipe is of poor quality, and the galvanized pipe is rusty and aging, which may lead to water leakage. We can only replace what is missing and eliminate what is missing. If the leakage is caused by the rusting and aging of the galvanized pipe, the galvanized pipe can only be installed at the leakage point, and the galvanized pipe is easy to be corroded, so it is best to replace all the galvanized pipes.

2. The height of the waterproof layer of the light body wall in the shower area does not reach 1.8m, and the light body wall is susceptible to moisture in the humid environment all year round. For the sake of home health and safety, experts suggest knocking off the wall tiles and making waterproof again.

3. Cracks appear on the external wall, causing the asbestos in the wall to be wet all year round. The asbestos in the wall is not easy to dry after absorbing rainwater. For many years, the internal wall will appear bleeding, mildew and powder loss. In this case, consumers should timely notify the property to repair, and should not solve it by themselves to avoid danger.

4. When building the house, the construction hole of the external wall was not sealed. Once it rains, the rainwater splashes into the construction hole, resulting in the moisture return of the inner wall, and the strip or ring like traces will appear after the wall is dry. Since the construction holes are mostly in the flue and exhaust holes, this situation usually occurs in the walls near the flue and exhaust holes. In case of this situation, it should be reported to the property management department in time.
