Hi! We had a new concrete driveway and sidewalk poured about 2 1/2 to 3 weeks ago. As you probably know it is not yet cured. Today a visitor parked on it, over a small area where we laid a cut up plastic runner, laying the pieces side-by-side to cover a wider area. Hard raid must have moved the pieces apart, because there was a small red spot of a red substance left on the driveway where the car had been. To test it out, my husband rubbed the spot with is finger. Some of the concrete crumbled away, leaving a small hole. With the same finger, he rubbed a black spot, not far away. He must have spread the first substance by doing that, because the concrete crumbled there, too. My question: Is there some way to repair or patch those holes so that they look decent, and will keep the original holes from getting bigger?

Thank you.

Your concrete was probably not of the highest quality for it to be crumbling and making pits at this point with just a finger! I would definitely consult with the company who poured the concrete driveway and have them explain the lack of quality. The concrete should have cured by now. Something is quite wrong. The concrete could have been "hot" and will never set up and cure properly. Sometimes concrete trucks have the concrete on it too long and the mixture becomes hot. This is normal for concrete to do this (heat up that is) and it should be poured off the truck way before it becomes hot. Many times the highway dept will test the concrete by taking the temp of the mix while it is still on the truck. A lot of times the entire load is rejected as it is too hot to pour. You might have gotten such a load of "hot" concrete. I'd raise the roof with the company who poured the hot concrete in your driveway.

Most concrete will cure to 70% plus in 1 week. Its been 2 1/2 weeks here. Hot load or top froze right after pour. The other is too much water was added while finishing it.

If there are problems now I guarantee it will get worse later..

Takes twinks advice and pursue it. Patching will not stick to a bad substrate id its not sound.

Call the contractor! Now, don't wait. Why should YOU do any repairs on a brand new project? I'm sure it wasn't cheap either. Good luck.
