Hello all:

The driveway for our new home has these weird spots in them. I've asked for opinions on other forums and have received a wide variety of responses, I'll try here as well, have any of you seen something like this? They were here before we bought the house and its only the lower part of the driveway not the entire thing. I don't see them on any other driveways or sidewalks. The builder tells me its normal. Any opinions/advice will be appreciated.
