ᐅ Rust spots on concrete – ceiling to wall – new construction

Hello,
Yesterday we had the final inspection (new build). There are 40 terraced houses, but it seems that only we have this problem.

There are several rust spots between the ceilings and walls on the ground floor. In total, we noticed 6 spots. Two rust spots are quite large, about 3cm (1.2 inches), another spot is about 5mm (0.2 inches), all distributed on the ground floor. Attached is a photo of the largest rust spot. The area is still damp.

The site manager said this comes from the connections between the concrete walls. He will fix these defects. We have the handover appointment in 3 weeks, and these issues will be corrected by then.

We recorded this in the protocol and accepted the house.

However, I couldn’t sleep last night. Is what the site manager said correct? If the defect is not properly repaired, will the house become unstable after a few years? It doesn’t seem easy to fix these defects.

What should we do now? Unfortunately, we have no experience with this...

Thank you very much for your help.

I suspect these might also be cigarette butts...

Hello

The idea isn’t that far-fetched. Smokers often think a discarded cigarette butt has simply disappeared.
Is construction no longer ongoing? I would suggest inspecting during the day with the help of a ladder, armed with a knife (of course, only to gently scrape away some plaster).
