ᐅ From when does the structural shell need to be dry or weather-tight?

What exactly do you mean by base waterproofing?

Waterproofing in the area of the first row of bricks against the concrete – for example, using a plastic-modified bitumen thick coating.
In our case, the waterproofing was not done by the plasterer, but definitely beforehand...

Unfortunately, I still don’t fully understand where this base waterproofing is supposed to be applied. Vertically, from the garage wall to the Poroton brick wall? I mean the area where the dark spots from moisture are currently visible.

My architect also says that the moisture likely comes from the garage roof. This is currently being waterproofed.

Hopefully, this will solve the problem.

This is how we handled it. The house walls are made of Ytong aerated concrete blocks. The first rows of blocks received two coats of waterproof slurry applied by the mason. On the east side, the house and the concrete garage are directly adjacent for three meters (about 10 feet). This area has neither waterproof slurry nor plaster, since that’s not possible—you simply can’t access it. Therefore, the vertical joint between the house wall and the garage was sealed with MS polymer. Horizontally, in addition to the waterproof slurry, a galvanized L-shaped steel strip was installed, fully bonded to both the wall and the garage roof using MS polymer. This makes the joint completely watertight. Karsten

Now that the joint between the garage roof and the house wall has been sealed, no more water has entered the house after rain.

The question is whether I need to keep it dry or if the plasterer can continue working on the interior walls. According to the plasterer and architect, work can proceed without delay...

Actually, it dries outwards. And the plasterer doesn’t apply enough of the render to the wall anyway.
