Mojo190Hello everyone,
Yesterday, the concrete slab for the basement of our single-family house was poured (not waterproof concrete), and today the formwork was removed.
I noticed that in some areas the concrete is very smooth, while in other places there are larger gravel pockets.
Additionally, some pipes were apparently installed a bit too deep and had to be "exposed," and in one spot a piece of wire is sticking out from the side of the slab.
I would appreciate your assessment whether these are just cosmetic issues or if there are technical concerns.
Thanks in advance

It’s unfortunate that the connections were chiseled out, but the main thing is that the reinforcement was neither damaged nor exposed.
