Wierd stain on new driveway
A few weeks ago, we replaced the 40-year-old asphalt on our driveway
with pavers. Yesterday afternoon, when I came home, I noticed a large stain that I am 99% positive was not there when I left in the morning. The pavers are grey. The stain is an orangish-brown (more brown than orange). The stain is roughly the same shape as the shadow that would be cast by the tree in the neighbor's yard if the sun were directly overhead. The tree looks like a birch or beech tree. It looks like something is dripping off that tree. Could it be sap? I stood under it and didn't feel anything and I can see anything. The stain is dry, not sticky. It's also very even, like it was painted oon, not speckled, so if it dripped, it was something fine. PLus, I;m pretty sure it happened in just a few hours. Does anyone have any idea what this could be and, more importantly, how to remove it? We never saw anything like this on the old asphalt driveway, which was also grey. I can take a photo if that would help. Is there some good place to upload it? |

Some fertilizers contain components that can stain. Have you or your
neighbor been spreading fertilizer? |

By the way, what kind of tree is it? I wonder if the sap has a high
tannin content. |

Has the tree been blooming? In Florida, we get so much oak pollen that the yellow powder can be seen on cars and pavement. Have you tried brushing or washing it off? |

I think it happened between 9:00 am and 5:00 pm. I just went out and took a few photos. The driveway is still in shade, so they aren't that good. I felt the pavers. They are dry (not sticky). I also felt the tree. It is not sticky and does not appear to be dripping anything. Puzzle... |

The leaves have been out for weeks. I can't see any pollen. Have you tried brushing or washing it off? I tried brushing and sweeping. No effect. It's definitely a stain. I haven't tried washing yet. Not sure what to use. |

Or, look at the leaves for the bugs. |

I also felt as many leaves as I could reach. They were dry (not sticky) and I could not see any insects or sap. I also called a local arborist. He said that if it was aphids, the stain would be black, not rust colored, and would be caused my mold (I think). He also said it could not happen in one day. |

Well, the pavers have been in for several weeks. We've had rain and hot days during that period. Whether they were wet or dry, they all looked more or less the same. No stains. Two days ago, this stain appeared in one day. It's still there. It does not follow the edges of the pavers. It looks exactly like the shadow of the overhanging tree. I didn't try the heat gun, because it's not close to an outlet. I'm going to try various cleaners today. If that doesn't work, I'll try the heat gun, but I can't see how that would explain the stain. Check out the photos I uploaded. (Posted to another reply.) |

A local arborist (by phone) ruled out aphids and he said pollen was unlikely. At this point, I am more interested in how to remove it. |

This seems to me to confirm that it came from above. 2. http://tinypic.com/r/i70xlj/6 This is a slightly closer view. The stain area was never "wet". 3. http://tinypic.com/r/21bkaig/6 This is a closeup view. Notice that within the larger stain, there are areas that are less stained. It seems to me that if it rained down from above, it would have stained everywhere about the same. Where the pavers from the same lot? As far as I know. They arrived on 3-4 pallets and I believe the wrapper had the same lot number. In any case, they were all the same color when first installed and the stain appeared in one day. Noticeing that the stain doesn't occur below the hedge, it is pretty clear that the stain is something dropping from the tree. Aphid dew, other bug waste, or pollen? I've only looked at the first picture so far. Looking at the lower portion of the picture, it looks like the strip along the edge nearest the hedge is of a different color, even where the "stain" isn't present. What was there before the pavers were installed? Contacted the contractor? County extension service"? Any work done in the area of the stain since the pavers were installed? I would not try any correction or cleaning before finding out what caused the stain. |

That's a concern, of course. Removing the tree is not an option, but if I can figure out what it is, maybe it can be treated or prevented. Or maybe that will suggest how best to remove it. It's a beautiful tree. If I have to clean the driveway 1-2/year, I'll live with that. We've lived here for 20 years and this has never happened before, unless it was not visible on the old asphalt driveway. |

Looking at the lower portion of the picture, it looks like the strip along the edge nearest the hedge is of a different color, even where the "stain" isn't present. You have a sharp eye! I hadn't noticed that before. I just went out to take a look at that area. The pavers that are under the hedge overhang do look cleaner or brighter than those just outside the overhand. Then I looked up at the tree. The tree that I suspect, actually is wider than the stain. It extends several feet toward the bottom of the first photo. But there is another smaller tree of a different species under it. I suspect that the smaller tree prevented some of whatever dropped down from reaching the driveway. You can't see it on this photo, but the stain does seem to extend to thge bottom of the photo. As you can see, the hedge is not straight. When we put the pavers in, we had to make a decision about that edge. We decided to have a straight edge on the pavers knowing that the hedge would overhang a bit in that area. We planned to cut the hedge back to a straight line, but haven't gotten around to it yet. What was there before the pavers were installed? It was an asphalt driveway that was at least 40 years old. The pavers are very close to the same footprint as the old driveway. Contacted the contractor? County extension service"? And ask what? Any work done in the area of the stain since the pavers were installed? The pavers have been in about a month. The city has been digging up the street for new utility lines. That started at least a month before the new driveway and is still not done. But I cannot see how that could cause a stain like this that has so many indications of falling from above. I would not try any correction or cleaning before finding out what caused the stain. I may not have that luxury. My wife has a big party on Saturday. I will be in hot water if the stain is not gone. I even suggested parking a car in that spot. |

If the contractor has been in business a while, he may have seen the problem before. My county extension service has entomologists on staff - they have answered all the bug questions I have taken to them. Your issue it so peculiar, it is maddening :o) Even if it is bug droppings, it is odd that the breeze didn't carry them into a broader distribution. I'd try laying down white cardboard to see what lands :o) I'm a dedicated detective and hate when I can't figure stuff out :o) Does the neighbor on that side have a sprinkler that could hit the area? Would have to be a mighty dose of rusty water to cause a stain in such a short period of time. Any work done in the area of the stain since the pavers were installed? The pavers have been in about a month. The city has been digging up the street for new utility lines. That started at least a month before the new driveway and is still not done. But I cannot see how that could cause a stain like this that has so many indications of falling from above. I would not try any correction or cleaning before finding out what caused the stain. I may not have that luxury. My wife has a big party on Saturday. I will be in hot water if the stain is not gone. I even suggested parking a car in that spot. Then you'll get oil stains and it will be YOUR fault ;o) Get a ladder out and have your wife climb up there and see what kind of bugs are in the tree... |

As for the clean up, pressure wash and what goes away goes away and what doesn't, doesn't. There are surely more significant issues to worry about???? -- |

They probably get saturated and take time to dry out. The pavers that were put down in the sun probably dried enough, but the ones in the shade are still damp. You probably noticed the difference because when the pavers were freshly laid, they were all equally damp. Spray some water on the dry ones around the shaded area and see if they all become the same color as the shaded ones. -- Bill In Hamptonburgh, NY In the original Orange County.

Why don't you just call the contractor up and ask him to take a look. He might know a helluva lot more than the people here. If not too many pavers are involved, he might even be nice enough to replace them for you at a reduced price or for free. |
