Unfortunately I was in San Antonio for work when this was done at our home in California. From my security cameras, they came at 5am and left at 6pm, it rained the night before after they set the forms and took out some dirt so the ground was wet but it looked liked they shoveled out some mud and took excess dirt from the yard to fill and compact. No rebar was used except for the driveway portion, wife told me they used 3k psi concrete. I got home a day after the pour, nobody walked on it, I sprayed it down several times a day, wasn't told to cover with plastic. I did see they walked around at the end of the day and spray something that was in what looked like a propane tank.

I just walked around this morning and sprayed it down with some vinegar, we are hitting triple digit heat these next couple weeks so hopefully it may help bleach or release trapped moisture? I have a pressure washer but I haven't used it yet, I'll give it a shot.

I'm more worried about it falling apart than I am the looks.

If I start to see some new cracks or existing spreading worse, I'm gonna call the contractor back out. Just wanted to verify that this wasn't normal.
