So you rented a bobcat to push your garage over? Don't you think you could have paid a couple of hoodlums to do that? Sorry if hoodlums is spelt wrong.

That was fun. Tomorrow is when I take out the 14" thick slab.


Quick, how much weight is there in a 14'x22'x14" slab?

[Mike K]

I paid for MikeC (All For One Roofing) to do it. The Bobcat also loaded the rubble into the dumpster and will be used to load the concrete into the dumpster once it is all broken up.

Too much!!!

Why in the world would there be a 14" thick slab under that?

Concrete weighs at least 100 lbs. per cubic foot, so based on those dimensions, you're looking at 30,000/35,000 lbs.

I saw 150 per cubic foot, if it has rebar. Stupid heavy, and I couldn't believe it was that thick either Randy. Dug under a corner and put a tape measure on it in two different places. Ridiculous amount of concrete for sure!

Maybe just the outer beam? You can hope?

[Mike K]

I have no idea. The whole building was put together on an extreme budget. Either the person that built the building had a friend that hooked him up with a lot of free concrete or he spent all of his money on the foundation and didn't have enough to build a nice building. Either way, neither one of us anticipated that much concrete.

I cut out two corners and started on a third, all three were that thick. I also used the jack hammer to peel back almost four feet into one corner and it never got thinner. Stupid thick!

Holy crap! Just figured it up and it's almost 54,000 pounds of concrete, if they maintained 14" all the way across!

14x22x14" @ 150lbs= 53,850

Dizzam! Mike, be there in a bit with two workers and a backhoe. We're bringing in the big guns...

take the bobcat forks and put under the concrete, lift and tilt down while pushing forward. it will break and flip the concrete up the size of the forks.

Makes you wonder if there's a body in all that concrete.

[mikec]

No body, Randy was right in that it had a really big beam. Put a Deere 310 on it and it peeled it up really fast. Once I got almost two feet in it was only 4" thick.

Looks good now!

[Vertnut]

Hell, even a broke clock is right twice a day. ;-)

Glad it worked out alright.

[mikec]

Me too man, really made me step back when I measured that stuff. Sure glad it wasn't that thick all the way through.

Like Mike said, it was a hatchet job, only one strand of number three in the beam, with wire mesh to hold it together.
