What should I do if the wall leaks in rainy days?

1. First, find out the reason of rainwater leakage in the wall. After finding the cause of water leakage, we can take targeted measures. If the water leakage is caused by the damage of the waterproof layer of the wall, after the rainy season, the grass-roots of the leaking wall can be eradicated, and at the same time, it is necessary to check whether there is any damage in the inner wall after eradication. Then, after the wall is cleaned, the wall is filled and polished to keep it smooth, and then the damaged waterproof layer is repainted with waterproof material and then coated with asphalt.

2. The bathroom wall leakage is a waterproof layer structure, and the waterproof height can't reach the national standard. The national waterproof design height of the back wall of the shower area must be at least1.8m. If you are in a humid environment all the year round, the bathroom wall. Not only the appearance of the house, but also the humid environment will affect the health of family members, so experts suggest tearing off the wall tiles to waterproof them again.

3. Cracks appear in the external wall of the building, which makes the external moisture enter the wall, leading to water infiltration into the wall. Asbestos in the wall is not easy to dry after absorbing rainwater. After a long time, the wall will become moldy, peeling and falling off. If this situation is found, consumers must immediately notify the building for maintenance, and the external wall of the building belongs to this project construction, not to home improvement. Don't solve these situations by yourself to avoid danger.

4. Uninstalled water pipes, the use of inferior water pipes, the use of rusty and aging galvanized pipes, and the water pipes that have not passed the pressure test may all lead to water leakage. If the galvanized pipe leaks due to rust or aging, only the galvanized pipe can be installed at the leaking place. It is recommended to completely replace galvanized pipes, because galvanized pipes are easy to corrode.
