Cracks in new concrete
 
4 Attachment(s)

I just had 1400 sq feet of concrete patio done last month, with color concrete, stamped. The contractor did the work on a very hot day, and then when I asked him if I should spray water on the concrete, he said no.

We had 105+ days for a week right after that, and looks like the concrete has not cured well. Right away nearly half of the controlled joints had long cracks, and cracks started appearing (and getting longer) on the concrete surface (see the pictures).

It also seems like the top layer of the concrete is not very strong, as I dropped a screwdriver from 3 feet height and it chipped the concrete.

The contractor says this is normal (no surprise there :-)). Is that correct? He says he will put a quick patching, and once the concrete is sealed, the cracks won't be visible at all.

What do you guys think? Thanks for your advice.
