How to Fill a Gap Between a Concrete Garage Floor and Apron

  • Transcript

    LESLIE: Betty in South Carolina has got a concrete issue. Tell us what’s going on.

    BETTY: We have a 5/8-inch crack between our concrete garage floor and the concrete turnaround outside: the apron outside the garage.

    TOM: Right. OK.

    BETTY: It has nothing to do with the garage door. Thirty-nine years ago, when the house was built, we think that they used a fiberboard of some type in this joint, because – for expansion and contraction. Now, that has deteriorated down – maybe down about an inch or so. And we would like to fill that crack. What do we fill that with?

    TOM: OK. So it’s not really a crack; it’s really just a gap where you had a separation between the two different pieces.

    BETTY: Yes, it was built that way.

    TOM: Right, OK. So, you’re going to use a flowable crack filler. And QUIKRETE makes those – Q-U-I-K-R-E-T-E. Their website is QUIKRETE.com.

    Basically, what you do is you clean out that space. You’re going to get it down an inch or two and then if it – then what you would probably do is put a backer rod in it, which is sort of this foam tube that will hold the filler exactly where you want it. And then you apply the filler on top and it flows to be nice and even across that gap. And then it dries in about 24 hours and that’s all there is to it. It’s really a pretty simple home improvement project.

    BETTY: OK. Thank you.

    TOM: You’re welcome, Betty. Thanks so much for calling us at 888-MONEY-PIT.
