ᐅ Concrete slab with defects?

Hello

I was pleased to inspect the progress of my build on Friday. The foundation slab has been completed. Aside from incorrect dimensions of the garage attached to the house, I noticed a few minor issues:

- The external perimeter insulation between the slab edge formwork and the concrete shows gaps of about 1 cm (0.4 inches) in several places, especially at the corners. What is the best way to address this?

- One section of the formwork has a slight curve and is not completely straight. The same question applies here as well.

- In areas where rainwater puddles have formed, you can scrape off a very thin layer of concrete with a fingernail. At these spots, the concrete appears to have fine cracks. Should I be concerned about this?

- On the concrete of the garage, especially along the edges inside the formwork, there are very small visible steel fibers. Again: is this something to worry about?

- Some stones in the edge formwork above show slight cracks. The same question applies here too.

Unfortunately, I was not present during the concreting process, so I do not know what preparations were made before the concrete was poured.

Thank you in advance for your help

B 500MA refers, to my knowledge, to reinforcement made from concrete bars, not fibers. However, I would strongly recommend that you simply consult the architect or structural engineer directly.

Especially since steel fiber reinforced concrete also needs to be properly consolidated --> EXPERTISE!

Oh please.... doesn't anyone think of recommending the OP to have a conversation with a local expert? With their architect... in my opinion...? Or an external specialist?

The information provided by the OP is so basic and amateurishly formulated that, from my point of view, it is irresponsible to even attempt an answer.

To be honest, this has already happened in many places... the original poster is just resistant to advice.

Then it only makes sense to stop writing altogether.
