I am the owner of Cangzhou Yuyu International City, and delivered the house on April 20 12. After the renovation, the wall was empty and the bulge cracked. Q: How to fix it is better.

The reason for this situation is that when the developer is building, the cement label used in the wall is not enough, or the proportion of sand in the cement mortar used is large, which leads to cracks and hollowing of the wall. This kind of situation can be repaired by the developer, but it is very difficult to repair, because the building can be handed over after acceptance. If so, there must be something involved, otherwise this situation is definitely unacceptable. Now that it has been accepted, it is very difficult for you to defend your rights. Because government departments have recognized this quality. Then you ask the developer, and he repairs it for you, because he is afraid of making a big noise. Once the sale of the house is over and it is no longer developed, then the developer will leave and the rest will be handed over to the property. Then you will be miserable, because the property will not participate in the housing quality problem.

Besides, you're definitely not the only one who has this situation. If this happens in other people's homes, you should organize rights protection and expose the matter, especially if the developers and houses are not sold out, they will definitely be repaired for you. Consumers in China are under great pressure. There must be compensation. It's just a matter of how much.

Let's talk about how to fix it. The big frame of the house is basically fine. The frame is basically water. The problem wall is the brick wall added at the back and the cement mortar of the powder wall.

Shovel off all the cement mortar on the original wall, and brush the wall twice to make cement mortar powder. If this can't be solved, brush the wall firmly, paste plastic gauze and brush cement mortar. This practice is recommended.

If not, you can smash the wall and rebuild it. This is definitely possible.

In fact, it's no big deal, just annoying. If you find a decoration company later, they can handle it very well. This kind of thing happened to me when I was doing decoration. We just told the owner in advance that if the wall is directly putty, there will definitely be problems. It depends.
