The cracks in the mortar of the external wall appear along the interface between the filling wall and the frame, and the lines are all horizontal and vertical. The joint surface is reinforced with steel mesh during the plastering construction of the mortar. As a result, the mortar has no hollows, and we have ruled out the quality factor of the plastering mortar. Has anyone encountered this situation? How to deal with this kind of exterior wall?
The frames in the second picture are all patched, but the general patching is probably not very effective.
