How to break up a concrete bumper

[gary300]

I have this concrete bumper in my garage installed by the previous owner of the house that I do not use and just trip over all the time. What would be the best way to break this thing up into a few managable sections that i could move easily? I have a compressor and air hammer with a few bits, and also a circular saw with masonry blade. Any help appreciated!

saw cut it, then cold chisel and a sledge.

Put it on craigslist for 10 bucks.

is it pinned to the floor? Put a pry bar under it and pry until something breaks

I like that idea. Or pay the neighbor's teenager $10 to get rid of it for you.

Take it out.....it most likely just sits of top of those two rebar rods sticking up.

If you don't put it on CL....just smack in the middle with a sledge hammer...

In my neighborhood....if I want to get rid of something...if it is somewhat 'usable'....I put it out at the curb the day before trash pickup....it's usually gone by the next morning.....funny how it works....

Don't forget to put the $10 sign on it! Nobody likes to take something that's free.

Those things are harder to move around than one would think. When you lift it up
with a pry bar, slip a 2x under it and tap on top with sledge. It may have pencil rod
re-inforcing inside so have a sawzall with a metal blade or side grinder on hand to cut.
Reduce it to 4 to 6 pieces to save your back and fingers. If the rebar pins won't come
out of slab, grind them flush with slab. Remember the safety glasses!

Looks like somebody (else) had a "non-parking" wife. ha ha ha

move the cars, pry it up, put it on a hand truck and haul it outside. then grind the pins flush and be done with it. i have managed to break one of those things with just a 12lb sledge, they arent anything crazy. smack it apart and then cut the rebar.

I work for a pre cast plant. Lift one end and drop it on a 4x4 it should break.

It's got rebar in it. It'll break but it won't fall into pieces like you'd hope. Bust it up with a BFH, toss the pieces in with your trash over a few weeks. Bend up the rebar and toss it separately.

Damnit, I need one of those!

As said above, it probably has rebar in it...so it will be a REAL ***** to cut/break.

Are you guys saying that the guy working in the friggin pre-cast plant doesn't know it has rebar?!!?

No, I'm saying metal reinforced concrete doesn't normally just fall apart without a SERIOUS amount of effort.

Also it looks kinda old - concrete never really stops getting stronger over the years. The Hoover Dam is still curing.

Well our regular parking stops are poured with out rebar. And some are poured with fiber mesh they will still break but you know ive never dropped one before in the hundreds of them ive loaded.

Looks like a blue handicap parking curb. You may be breaking some kind of law.

Pry it up, then stick it on a dolly or two-wheel cart and put it at the curb on a couple 2x scraps to make it easy to grab. Someone may have a use for it. If it is not gone in 2 days then break it up with a sledge and trash it. A few blows will do it especially if it is on blocks. Concrete is brittle even if reinforced. Cut or bend the reinforcement once it is free from the concrete.

Have any problems with people speeding in front of your house? It would work really well as a speed bump in the street.

OK, I tried my best to break this thing up witht the biggest sledge I could find. All I managed to do was chip it! It must be made from the concrete from hell... I did try my air hammer on it and it looks like I could eventually break it up, but would take a long time and make a big mess. I'm thinking now I might just cart it out in front and let my local garbage pickup handle it. I get two free large/heavy object pickups a year.

Well, that is an idea but I think it might piss off the neighbors and make a bigger mess than the air hammer rout.

Explosives AND ******* off the neighbors? I don't see a down side!

You could try drilling a series of holes in the middle...after a while, whack it again with the hammer.

+1 if you insist on doing it in a civilized manner. Just did a concrete foundation this way and it worked if the holes were less than 3" apart. HOWEVER, I'm lobbying for the explosives. Any garage project that potentially involves homeland security, media coverage and the bomb squad is obviously the way to go!
