1. Poor foundation: the building foundation is not firm, and the bearing capacity of the foundation is insufficient, so the wall will crack.
2. Excessive humidity: If the wall suffers from too much moisture during construction, the concrete will expand excessively, resulting in cracking of the wall when it shrinks again later.
3. Lack of technology: The technical level of the construction workers is not high, the technology is not fine, and it is easy to shake hands, which leads to the cracking of the wall after decoration.
4. Wall material problem: the quality of wall material is not enough, which leads to cracks in the wall.
Treatment method:
1. Check the problem: first, find the cause of wall cracking, and then solve the problem pertinently.
2. Re-check the door frame: re-check the combination of the door frame and the ground, and then repair or reinstall it.
3. First attempt to repair: If the crack is not big and the shallow damage does not constitute a safety hazard, materials such as glass fiber reinforced plastic cloth can be used for hardening agent remedy, and then plastering and painting can be carried out.
4. Replacement in case of major damage: If cracks are found to be too big to be repaired, only new door frames can be replaced and renovated.
In short, in the case of cracking of the door frame wall after decoration, we need to find out where the problem lies and take corresponding treatment methods to ensure the quality and safety of decoration and avoid safety problems.
