Of what I know about concrete is that it dried too fast. Should have been
covered from the sun or kept cool with water spray. This is common with
concrete 3 inches or thicker.

Almost two weeks ago I had 3,100 sq ft of concrete poured for a driveway
and apron in front of the garage. I was told to let it cure for 7-10 days
before driving on it. We gave it 9 days before pulling one car into the
garage.

13 days after pouring, I've noticed I have 3 major cracks in 3 separate
sections. The cracks run right through the expansion joints, from one
side to the other of the drive and are spaced about 20ft apart. They are
about 100ft from the garage and apron sections.

The contractor is coming over this week to check it out and I'm wondering
what demands I can make to cure this? He has not been paid yet!

What are my reasonable options to fix this?

Thanks,
