Why does the external wall of Bozhou Evergrande City fall off?

1, the construction technology does not pass.

2. The skin of the building exterior wall is actually a coating layer, and the construction of the coating layer can only be carried out after the cement layer of the exterior wall is dry. However, in order to catch up with the construction period, many builders directly painted the cement layer before it was completely dried, resulting in the internal moisture just spreading outward. Over time, the paint layer will peel off and then fall off.

3. In the process of designing the house, the developer will install insulation layer on the external wall. During the construction of insulation layer, water conservation should be maintained. However, some construction parties did not pay attention to this, and the watering times of the insulation layer were not up to standard, which led to the insulation layer falling off in the future.
