Why do many walls always leak when it rains in summer?

In the continuous rainstorm, many places have become "looking at the sea" mode, and the roofs and walls that have been "baptized" and "hit" by the rainstorm are prone to cracking, water leakage and mildew. What should owners do for books? Don't panic, to deal with this problem, first of all, you have to know what is the reason for the wall seepage. Only by finding the root cause can we "prescribe the right medicine".

1. What causes the wall seepage?

1, many residential walls have no protective layer.

Many houses have no insulation on their walls. In winter, due to the large temperature difference between indoor and outdoor, the wall is cold outside and hot inside, and the inner wall will form condensed water due to high temperature. This situation will only appear in winter, but it will get better in summer, but it will leave many ugly mildew spots, which will affect the overall beauty of the wall.

2. The water pipe embedded in the wall leaks

Generally, the wall moisture caused by the water leakage of the embedded water pipes in the wall mostly appears near the bathroom or at the top of the house, mostly because of the problems of the embedded water pipe joints, including whether there is water leakage in the wall at home and upstairs, and water seeps into the partition wall.

3. The waterproof measures upstairs are not good

First of all, it may be because the waterproof project of the upstairs floor is not done well, which leads to water leakage on the wall, especially the waterproof floor of the upstairs bathroom. Once there is water in the bathroom, it will slowly seep down. Secondly, it may be that the joint between the upstairs water pipe and the ground is not waterproof, and it is likely that there is water seepage near the pipe, and the water flows down the water pipe, resulting in water seepage on the roof.

4. Improper construction during painting

When I was painting the wall, if the wall paint didn't dry thoroughly the first time, I began to paint it the next time, but the water vapor in the wall didn't evaporate, which caused the wall to be wet.

Second, how to deal with wall seepage?

1, replace the water pipe. If it is because of the water pipe, you can replace the water pipe, or temporarily repair it with the special tape for repairing the water pipe first. The specific operation method is: first close the valve and cut off the water supply, then open the faucet to a suitable position to release most of the pressure in the water pipe, and then tie the leaking part with special adhesive tape or seal it with epoxy resin glue.

2. Contact the property for maintenance. If it is caused by the leakage of the external wall or the situation that cannot be handled by itself, it is best to report it to the property and contact the engineering department for maintenance.

3. Buy waterproof paint to plug the leak. Owners with water leakage at home can buy waterproof coating for plugging and paint the bathroom walls and floors themselves. The best way is to ask the decoration workers to solve it, which is more professional and effective. Or waterproof it again, it will be a little troublesome.
