Moisture on the house wall outside and inside

I still can't imagine that it comes from outside. Otherwise, other places would probably be affected as well.

Hello Nepokat

you piled up and paved yourself. You have to blame yourself for not doing the necessary preparatory work.
Now you have to remove the entire filling and leave it open until the wall has dried. Then again, this time properly, from the beginning.
And let it dry for a long time. The moisture is deep.

I don't see it that way at all. He has had the hole open for 2 weeks and no water collected. The wall still got wet. Overall, it's not good, but the pipe is not the problem.

Get an expert or remove more stones to see exactly how it was processed behind. I still have the feeling that it comes from inside and not from outside. Put in a floor plan and turn off the underfloor heating in that room to completely rule it out.

Hello

Underfloor heating would be noticeable. Pressure loss in the circuit.
The KG pipe seems to be tight.
The capillary effect of the soil is responsible. The way the thread starter paved it is not how it is done.

Hello everyone,
before I call in an expert, I need to make sure that it is not our fault.

Since we definitely raised one stone too high during the paving work, thereby creating a bridge for moisture, the black foil on the red stone is pointless.

The soil now has no physical connection to the clinker of the house wall; I have removed everything from the door to the window.
On the back of the house, the paving is exactly one stone lower, and we do not have this problem here either:







I will now observe the wall and hope that it dries; if that is not the case, I will have to order an expert.

As already mentioned, there is only the underfloor heating behind the wall, which is still at 1.6 bar.
It has not rained in the last few days, and as you can see, nothing has visually changed on the wall.

So now we will wait a little bit.

Don't you have any pictures of the construction work?

So we will wait a little now.

Hello Nepokat

you will have to wait a little longer until the bricks are dry. But this is the right way.
Let it dry well. Not just visually, the moisture is inside the stone and that takes time. I think you won’t be able to finish it this winter anymore. When the sun comes out in spring, you rebuild it and then it will work.

I find the statement to involve an expert only when it is certain that you are not at fault somewhat strange.

After all, this is about your property and it should be important to prevent consequential damages as quickly as possible. Very valuable tips have already been given here, but I would definitely involve an expert immediately to ensure clarity and that the correct measures are taken...
