How to Fill Cracks in an Asphalt Driveway

  • Transcript

    LESLIE: Terry in Iowa, you’ve got The Money Pit. How can we help you today?

    TERRY: I’ve recently laid blacktop down probably about two years ago. Now, I’m starting to get some cracks in there. And some of them might be at least a ½-inch wide to ¼-inch. And I’m curious if you have a new product you’re aware of, that was rated highly, to use now to fill cracks with on blacktop?

    TOM: Well, it’s interesting that the driveway was only two years old and it’s already forming cracks. That can mean one thing and one thing only, Terry, and that is that it wasn’t put down very well to begin with. Perhaps the base wasn’t as solid as it should have been. Is this a project that you had a contractor do for you?

    TERRY: Yes. And you’re absolutely right. What happened – I didn’t get the 3 inches I was guaranteed to get. And I drive a semi and in the wintertime, I’ll back my semi up there to plug it in due to the cold weather. I live in Wisconsin.

    TOM: Right.

    TERRY: And I got off on the edge a little bit and it pushed it down.

    TOM: OK. So, what you want to do is use a latex asphalt crack filler. And then also use a latex top-coat sealer. The latex products today, the formulation is pretty good and they’re a lot easier to work with. But don’t use the sealer on the cracks until you put the crack filler in first. The crack filler has some depth to it, so it can fill up those voids – those ½-inch voids – that you described. Then after you apply the crack filler and seal those cracks up – because, remember, what the purpose of the crack filler is really is to just keep the water out of it and keep it flush so the water doesn’t get in and freeze and make it worse.

    So use the crack filler first and then put a coat of latex sealer on the whole thing. I would just buy one of the squeegees on – with one side, the broom on the other – kind of application tools. Start on one end, go to the other and then stay off it for a couple of days.

    TERRY: Well, thank you very much. I appreciate your kindness in answering my phone call.

    TOM: Terry, good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
