I went with wire based on recommendations from other professionals in the area. And the wire was much cheaper than the rebar.
They pulled it up as they went. I spent the whole day watching them prep, pour, and finish the floor.
Sorry to hear this. As a contractor, one of the biggest red flags that I encounter is a concrete guy saying that they can pull up the wire, or rebar as they go. As you can see in your pics, it doesn't happen. Wire is 100% impossible to pull up and then walk on and keep inside the concrete. Rebar has a chance, but in every slab that I have cut open, it's laying on the dirt or plastic, not doing anything.
Wire is OK for walkways where you can keep it in the middle of the concrete and not walk on it. Rebar on chairs is the only way to do a big pad.
What's done is done. Cracking is mostly from too much water and the rebar, or wire is mostly there to hold the cracks together so you don't see them. When it's in the middle of the pad, it does a great job. When it's at the bottom, it doesn't accomplish this. If your pad was poured with as little water as possible, you shouldn't have any issues. You will know for sure in about a month. If there isn't any cracking by then, you're fine.
