ᐅ Demolition and reconstruction of exterior wall due to defects

Hello everyone,
the exterior wall of our ground floor shows the following defects:
- Overlap dimension undershot by 50%
- Installation not compliant with building authority approval (bed joints were not fully filled with mortar)
For the issue of insufficient overlap, fiberglass mesh plaster can be used to minimize cracking risks.
But how can bed joints be fully mortared afterwards?
The installed masonry unit is: Bellenberg MZ70
Now for the main question to an expert: Is it possible to replace an exterior wall when the ceiling above has already been poured?
What is the best procedure to do this?

Incorrect overlapping length and insufficient mortar are structurally significant. You don’t want to live in a structurally unstable house. Whether the concrete ceiling above can only be saved by demolition and rebuilding, I cannot assess. An expert will provide you with clarity. I really hope your masons don’t make things difficult. Good luck!

I really hope your bricklayers don’t make things difficult. In my opinion, you’d really have to use the intensified Bavarian form of denial here: they are definitely not bricklayers, no way. I also doubt that anyone would hold a floor slab up on supports and a crane in midair until new walls are built underneath it ;-) But I don’t expect a flawless ceiling here anyway. My general doubts about the contractor’s expertise remain. Is this a mailbox general contractor who loads his pickup truck project by project with temporary workers from the “labor market” – naturally all with their own business license?

An expert has now been involved. He also says that using regular mesh here won’t help. At best, ribbed expanded metal or brick lathe mesh might work. But these are materials typically used in renovations rather than new constructions. I'm starting to feel quite desperate.
Given how the construction company is acting, it’s clear they won’t just dismantle everything without a fight. These aren’t even all the defects. There’s a concrete basement with gravel pockets, drainage that doesn’t comply with standards (DIN)... Oh dear. We have withheld the last two progress payments for now. We hope to be able to enforce our rights through legal action.
The construction company is a local one.
Hampshire and 11ant, are you experts yourselves, or how did you acquire your technical knowledge?
