would you accept this concrete driveway

Fiber concrete? Any expansion joins, wire or rebar?

I wouldn’t accept cracks like that on something poured a few days earlier.

I’m interested to see if they replace it for you. I had the same thing happen to mine and they told me it was normal moisture cracking that’s common and wouldn’t replace it. I totally think I got screwed and find it unacceptable, but I lost the battle and wasn’t going to go to court over it. I just wanted my house finished

3 things. too much water in the mix, no curing compound, or curing blankets/sprinkler was used to cure. the house two doors down had curing compound applied and i think it did not crack. i'll go check it out tonight.

Like the one guy said im not going to court over it, but it is crappy workmanship.

I would be hesitant to accept it. But good luck not accepting it. If that makes sense.

Understood. I too had a less than desirable driveway pour when my house was built in 93 (May) - rushed to meet a closing deadline, but not with the severity you seem to have, but here I am today and I really need to replace my driveway. Best of luck getting this resolved

High percentage of fly-ash in the mix (ie. cheap concrete) will do that too. A strong mix without curing will have reduced strength but should crack at the joints, or inside corners, not out in the middle.
Also, in high temperature conditions, batch plants will add ice to the mix in to keep the concrete cool. Think about that pile of aggregate baking in the sun at the plant, and cooking your concrete as it make the trip from the plant to your house. The finisher has to add water when he pours as the mix as probably started its initial set in the drum.
Another point, I don't see any vapor barrier. It works both ways. If the sub-grade is hot, dry, sand-clay, the earth will suck the water right out of the mix, resulting in cracks.

10$ to a dime, concrete sub blames batch-plant. Sub should have checked the batch time and temp and sent the truck back.

You don't tool in expansion joints. A tooled joint is a contraction joint which induces where the concrete will crack.

To me it seems the concrete cured too fast for cracks like that to be showing up in the middle of the pour after only a few days. All concrete cracks, certain things can be done to minimize said cracks, but cracks will happen.

Not on a residential driveway. Typically a 28-day break 3000psi mix is used.

Thanks. Good info.

When Mom and I were shopping houses last month we flat our rejected a few over the shoddy concrete in drives and garage and patios. I saw 2 of the higher dollar homes where 1 crack started in the drive, went through garage, through to the far end of the back patio, obviously through the house slab. One of the houses also already needed the garage replaced as it was making circular cracks already chipping out chunks. These were brand new homes, completed this year.

The house we're moving into next week has nice concrete, the driveway is even contoured for drainage across it and not just a flat level slab (matches the house next door drive contours also same builder). Builder obviously watched/noticed the runoff from the uncommonly wet year.

You can’t be serious. Yes it’s cheaper to use fly-ash but it’s not inferior. In fact, it’s better in these summer conditions due to its slight retarding properties. So many factors go into these types of cracks. Most of the cracks appear to be cosmetic which sucks because it’s a driveway. I’d be shocked if they remove and replace.
