Our concrete driveway has a hump in it just high enough to scrap the bottom of most cars. How difficult would it be to get someone out here to scrape it down a bit?

i would bet you need to re-pour a section if its high enough to scrape a car, i have no idea what you would get quoted for that

7/28/2010 6:42:00 PM

Do you have a tree root causing it to bulge or was it poured that way?

Just keep driving the car back & forth over it...eventually it'll go away

provided the slab is thick enough you could rent something to grind it down with

Getting paid to grind for LoneSnark has been a dream of mine for years.

7/28/2010 7:11:26 PM

ahaha

probably be easier to just pour more and level it out

7/28/2010 7:41:01 PM

I feel like grinding it down and decreasing it's thickness much will leave it much more likely to crack under the weight of a car.

I'd say your best bet is repouring.

Just all of a sudden just jump up and grind on LoneShark's driveway, like it's, like it's you know something to do. Come on, I got a little more sense than that.

Yeah I remember grinding on LoneShark's driveway.

who the fuck is LoneShark

7/28/2010 8:14:56 PM

get an suv

1.) bust it up with a jackhammer (or sledge if you're man enough)
2.) remove busted-up pieces
3.) buy quikrete, pour
4.) level out with a rake and spade
5.) ...
6.) profit

It depends on how much scraping is going on, is this just like a nick, or is the car dragging? Your driveway is maybe 3" thick at most, so you could probably get away with taking it down 3/4" - 1".

^^ You have to make sure to joint it though, there is probably a joint at the crest where it is scraping, so if you take that away and just fill it in, then when the concrete expands/contracts, the whole driveway will crack.

7/29/2010 9:40:18 AM

just make a crack/joint every 10 feet or so and you'll be fine

all you are trying to do is create a crack where one would occur on its own

How thick is the concrete?

7/29/2010 12:19:51 PM

We have the same problem here at our house. Some days I want to go out there with a sledge hammer and beat the damned hump out.

7/29/2010 12:44:14 PM

I estimate that if you could harness the energy of people venting in The Soap Box, you would have already had all the concrete pulverized. A little work with a hoe and wheelbarrow and that driveway would be good as new.

don't forget to think about how water will drain on your new slope

7/29/2010 1:16:31 PM

Have you considered redoing the whole thing with a stamped design?

7/29/2010 5:54:43 PM

Stamped is junk, go with pavers if anything. You could do just the apron.

Did the hump rise up and that is what is causing the issue or did the adjoining slabs sink? If the adjoining slabs have sunk and that is causing the problem, you can get a company like RamJack to come out and jack up the adjoining pads for a few hundred dollars. They drill small holes and pump foam that expands and will give you a lifetime warranty that it won't sink again.

If it is due to a tree root or something causing it to rise, I would recommend demo'ing it and re-pouring it with a 4" thickness. I would guess you could do this for under $2K for a 10 x 20 section.
