Hello,
is it necessary to seal the vertical joints of a 36.5cm (14.4 inches) exterior wall behind a pre-wall installation to prevent moisture from penetrating the masonry? Without sealing, the joints would be protected on the outside by plaster and on the inside by drywall panels plus tiles. The general contractor has not sealed them so far, and the rough installation is complete.
Thank you very much for your answers!

An expert who inspected the shell construction suggested that sealing the vertical joints around the pre-wall installation would be necessary to protect the masonry from moisture.Your expert surely can’t be serious about that (see highlighted area)? https://www.instagram.com/11antgmxde/

But that’s how it is. As a layperson, you believe it at first, but then doubts arise, which is why I asked here.
On this occasion: My general contractor (GC) does not want to plaster an exterior section of 7m (23 feet) because this wall is covered by a prefabricated garage located about 20cm (8 inches) beside the house. Of that, 1m (3 feet) on the other side of the wall is also within a cavity wall installation area and therefore not plastered on the inside either. Is this structurally acceptable? It would not be visible since it is covered by the garage.

If the garage—which already seems like at least a logistical planning mistake—is standing 20cm (8 inches) away, it only "covers" the wall visually, right(?)

The general contractor (GC) is not responsible for the 20 cm (8 inches); rather, it is the neighbor who is using my airspace for a metal sheet on his garage and has not dismantled it. Additionally, the GC is reluctant to take the risk of installing a slightly larger garage with extremely limited space on both the left and right sides.
If I understand your response correctly, there is a risk of moisture penetrating the masonry, at least if there is no tight connection to the house?

The risk is that this is problematic in several ways. It’s best if you show the whole situation, including the plan and several photos. Also, the blower door test will hardly show an airtight house without the exterior render...
