Hello everyone,

we are currently thinking about how to clad our protruding plinth (upper floor with 49 cm Ytong wall to the basement with 30 cm concrete wall). What options are there for this?

In the attachment you can see the section of the components with the thicknesses:

The red arrow points to the edge which still poses a problem for us because we don’t know how to clad it. Because in the houses we know it’s exactly the other way around: the plinth is set back and the facade hangs over it. But due to the thick XPS insulation and the concrete wall located centrally under the 49 cm exterior wall, one comes at least 4 cm in front of the facade wall. Is this a problem?

Solvable with a sheet metal like in the following picture?


Do you do it in such a way that you stick a fabric tape on the perimeter insulation and then plaster or clad it differently (stone, sheet metal, whatever). And you clad the protruding "problematic" edge with sheet metal as shown in the picture? Or what alternatives are there for this?

What is important is that you have a drip edge from the main wall (facade) and thus don’t get a moisture problem, right?

We are grateful for any tips and advice.

Sunny greetings to all forum members from BaWü

This must actually be technically planned within the scope of the construction. How is the perimeter insulation currently installed (base coat with mesh, base plaster, final coating, dimpled membrane, etc.)?

Sorry, but whoever planned it that way must have sat right next to @goalkeepers mayor in school, that is really textbook blond.

Is the stone even allowed to stand "on the insulation" or extend beyond the base plate?

I actually only know that stones are placed at the outer edge of the base plate.

Is there an execution plan to answer the above questions?

I only know it the other way around, the stone should protrude a bit to form a drip edge... that's how it was done with us. The first 2 stone rows are a 30 cm Ytong and they are flush with the base plate, and from the 3rd stone row the 36.5 cm Ytong begins, which protrudes 6.5 cm. On the 30 cm stones there is then a perimeter insulation, which is not 6.5 cm thick, in order to form a drip edge. With your variant, it is just preprogrammed that water will run in.

How does the question arise here in the forum? For such technical information, the interested builder usually hires an architect. After all, the architect is also liable for their planning.
