ᐅ Fill vertical joints of the 36.5 cm exterior wall behind the drywall installation.

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!

These butt joints are usually left dry nowadays, typically tightly butted. Therefore, I am confused about what exactly you want to fill there.

An expert who inspected the shell construction said that by sealing the joints in the area of the stud wall installation, the masonry should be protected from moisture.

Could you please take a photo showing exactly where the problem is?

What do you mean by a surface-mounted installation? I think the 36.5cm (14.4 inches) block will be plastered anyway. That should make it airtight. K

Here is a picture of a joint; others are similar.
