Hello everyone,
I have an appointment with my site manager next week. Before that, I wanted to gather some opinions and maybe someone has already experienced the same issue or at least seen it before.
The problem is as follows:
Last week, when it was raining very heavily and the wind was quite strong, our facade suddenly looked like this (see photo). You could clearly see the joints of the blocks through the render and there were slight cracks in the base area. Does anyone have any idea what this could be? Could this indicate a construction defect? For example, an insufficient base coat thickness?
Details about the house:
Year built: 2016
Masonry: 30 cm (12 inch) Ytong blocks, glued
Render: according to the building plan, 15 mm (0.6 inch) base coat and 3 mm (0.1 inch) top coat

Well, what counts as minor issues? What doesn’t?
I am fully aware that other problems can or will occur. But they don’t have to. And to me, that is just as bad as plaster falling off or mold developing.
Do you also consider that minor?
I also don’t think this is normal. I have never seen it before. To me, that means it is not standard. Any counterarguments?

Does the water run down the facade there? Because it’s also on the base of the wall (which doesn’t look very good either), but there is nothing visible under the window sills.
