Yesterday as I was digging a fence post hole I hit an obstacle about a
foot down, and ultimately dug out a big blob of concrete. Looks like
it was how some previous owner set a fence post. It's an 18-inch
diameter blob (roughly spherical) of concrete with a shallow (maybe 6
inch) hole in the top. This thing is way too heavy to put out with the
trash. So, how do I break it up for disposal? (After digging this
thing out of the ground, believe me I have already thought about the
pack-the-hole-with-dynamite option, but don't think that would conform
to local ordinances.) -- H
I've found that a decent sized sledge hammer works well (wear your
If you're not looking to suplement your weekly workout in this manner,
you could rent/borrow a small hammer drill with a spade bit and chop it
up that way.
If you live in a cold climate, you could do some science experiments
with water poured into the hole and allowed to freeze, and maybe
alternating hot/cold to thermally stress it. These methods will take
some time, but could be interesting to try out if you're into that sort
Around here, our trash collectors won't take any concrete.
Call the city garage. That's what I did when I had to dispose of
concrete from an old sidewalk. They didn't charge me a dime either.
I just used a sledge-hammer to break it up. Not sure how well that'd
work in your situation, though.

I'm told that concrete can be ground into aggregate to be used in
construction, presumably as concrete fill. You should be able to recycle
A big sledge will get er done. Eye protection, jeans and long sleeves
are a must.
If you stay at home on garbage day and have it in chunks small enough
to be lifted safely, a generous tip to your refuse collector tends to
make it disappear.
I've been trying to break up a 30 gal drumful of concrete with a big sledge
for a few days. Each humongous blow dislodges a teaspoon of concrete. Where
can I buy a "plug and feathers" aka "rock jack" or some expanding powder?
throwing it into a dumpster is stealing. Someone has to pay to get that
removed , probabley has to pay by weight. So the extra cost has to come from
someones pocket. Same as stealing his money.
I recently bought a 16# sledge from home depot for smashing an old
sidewalk, it worked well. i put a little muscle into it but for the
most part i let the hammer do most of the work.

Yes! That is the right way to break up concrete. Full force, round
house blows are great for building muscle mass but are wasted effort.
What does it are repeated moderate blows in the same spot (or in a line
if breaking a slab). At the start it will 'ring' with each blow then
after repeated blows "thud" . The block or slab has cracked.
It's easy to break it up. Take it to the roof of a 5-story building,
and throw it off.
Or you could rent an electric jack-hammer. That might be overkill,
but it's better than no plan. A contractor next door let me use his
jack-hammer. It was surprisingly easy. The hard part was lifting it
back up after it went through the sidewalk. The handles were as high
as my shoulders, so that made it worse. I'm 5'8". I felt like I had
a workout after only 3 or 4 minutes. But you'll have 4 hours. Wear

Suggestions for the blob:
1. Put out by curb on garbage day, topped with a chilled six-pack.
2. Leave in schoolyard in about two weeks (during dark of moon). Dilbert's
boss did that with an old refrigerator.
3. Clean. Paint green. Place on city hall lawn with plaque: "Honoring the
