Severe weather warning tomorrow, red level for our construction area!

So far I do not have an expert, I am now waiting for the opinion of the site manager, after that I will probably take care of finding an expert for the whole construction.

I would definitely do that too. Regardless of what the site manager says

I don't like it either, just based on gut feeling. Do you have an expert? I would get one, even if it's just for the foundation slab

I don't see anything concerning there. It's maybe 1-2cm deep. But what is that anyway in construction?

I think he means the accumulation of small stones in the corners. Mason forward. Isn't there anyone here who's a professional? Karsten

I do have my concerns there. Also because of the compressive strength in the corners. But mainly because of the inadequate concrete cover of the reinforcement steel. It certainly has only millimeters in some places or is even partially exposed to the air.

Search for Kiesnester! I am of the opinion that it is a defect.
