Fixing uneven driveway grade?

Is there a way to mix and add a little more concrete to one of the sections of my driveway (10'x15') which has a slight grade that allows water to drain off to the side versus down to the street, causing some flooding of my front yard. There's a gutter too that drains onto the dirve contributing to the water runoff.

BTW the 10'x15' is but one section of a fairly large drive. I'm thinking it would need to be ground down some then re-pour another layer??????

When the drive was poured (1.5 months ago) that particular area of the drive seemed to settle more than the rest. Water pours down thru the downspout onto the drive in front of a set of sliding doors. The water then slowly makes a left turn towards my font porch area which is level now the drive causing a buildup of rain water under the low profile front deck walkway instead of continuing it's way towards the end of the drive and a drain running parallel to the street edge. Each section is separated by wood expansion joints.

I've already told the contractor he needs to come back and find a way to fix this without making it look odd. I told this guy over and over i wanted to be sure the rain water would channel to the street and away from the house. My previous crush & run driveway would during a heavy downpour type rain storm actually pool up to the point it would find itself pouring into my crawl space. So the goal was to elminate this from ever happening again. But as mentioned, the water in this section is again finding it's way near a crawl space vent. I'm afraid in a very heay rain day my crawl space problem will still be there.

So i'm wondering what to expect from him, and or what to drive home to him if I get a bunch mumbo-jumbo out of him short of actually jack hammering that section out and pouring again.

Fixing uneven driveway grade?

If it settled in the first 1.5 months, then the contractor did not do a good job of compacting the soil. It may continue to settle more.

The best solution is to have him rip out the panel, add the base or remove the bad soil and recompact. Then pour a new panel at his cost. - If you just hired him to pour and finish the concrete (labor only), it could be your responsibility.

Base was several inches of crush and run that has been in place for roughly seven years. So I think the base was solid, it was just the air or whatever in the cement itself wasn't worked out, or the pour was spread out too thin in that section or panel as you call it. It's just disappointing that in spite of really harping about wanting the correct grade for drainage, it wasn't done right or really focused on closely enough.

It was not the air in the concrete. - You can't possibly have enough air and water in concrete (not cement) it to account for 1/32" over a few years

Either the base settled or it was poured low.

Don't let the contractor mislead you!

Sounds like simply poured low. And it has only been 1.5 months on a solid crush & run base. I'm "still" waiting on him to call me back after he said he'd be out to figure something out.
