Braking concrete
 
I bought a house that has a 5'x6' concrete pond. About all it is good for is breeding skeeters. It has a 8"x12" footing all around it. What is the easiest way to brake this thing up? I beat it with a sledge but didn't get anywhere. Renting a jackhammer is not in the budget at the moment. Any easy way to do this? Thanks

If you want cheap, keep bashing at it with the sledge hammer. If you want easy find the $ to rent the jack hammer. No easy way without the jack hammer. You could try drilling holes in strategic places to assist with cracking.

Neal, think this expanding mat'l would be less expensive than renting a jack hammer for 1/2 day?

I was looking at "ecobust". They want you to drill 1.5" diameter holes. How big of a rotary drill would that take? Anyone have any idea of rental cost for the drill and bit?

They may want you to buy the bit, tell them what you are drilling so they rent you a size appropriate drill.

@thunderhead

Easy breaking up concrete is a fantasy

Spend the dough and get a jack hammer

You should be able to rent an electric jackhammer for around $40-50 a day. Dexpan would probably cost 10x's that for the same effect....

If you keep after it with a sledge hammer it will break. Once you get one section broke up the rest will be easier. Is there any chance of rebar being in the concrete?


Pool chemicals and aeration will prevent the pond from being a breeding ground for bugs.

+1 on the electric jack hammer, I once broke up about 100' of side walk and a front porch slab with one. I don't think it took much than a hour to bust it all up.


And the rental on the core drill is probably similar to the rental of the hammer.

I don't know about rebar, sure hope not!

There are some cracks and it leaks so I don't want to keep it.

I will check into the electric jack hammer. Thanks for the replies.

Let us know what you do and how it goes.

I used an electric jackhammer to break up a large area of concrete in front my house. Fortunately, it wasn't full of rebar.

GIRD yourself for some nasty physical labor. I'd use the jackhammer to break up the pieces, take it back to the rental yard, then dispose of the "rip-rap" that results.

Oh, yeah, more fun than herpes, tossing that rip-rap. If you aren't in shape to start, doing that will put a long ways there . . . . :biggrin2:

I was able to get rid of that for free by Craigslisting it in the freebie section and some guys came by and used it to stabilize their slope against erosion.

If you don't want to do that or, can't for some reason, you'll probably need to rent one of those dumpsters for construction debris. I'd look into what that might cost and plan ahead a bit, and don't be afraid to ask more questions here if need be.

I think, for what it's worth, getting rid of the pool is a good idea if you know you aren't going to swim in it. Pools are magnets for little children to fall into and drown and die or get brain damage. Ponds, too. Little ones can drown in 6" of water.

Yeah, maybe put on some jailhouse stripes and get someone to honk on a harmonica while someone wails those "busting up concrete with sledgehammer blues." :biggrin2:

I did that once, without the stripes or the harmonica.

Once was enough. It channeled a lifetime of bad feelings breaking that driveway.

Yodaman had an easy time with an electric jackhammer. I had a hard time with one. I think the difference is in the thickness of the concrete. I can believe a jackhammer will have an easy time through 3" slab. Mine was maybe 10" thick. I am predicting OP will have a real fun time with that footing --- hope that's 12" wide, not 12" deep.

Depends on the quality of the concrete.

Breaking up concrete is never easy, like breaking up a concreted relationship.:vs_cool::vs_mad::devil3:

Several yrs ago I tore down a 150 yr old house that had a bath rm added in the 80s. It was in a small addition on a 4" concrete slab. I thought I'd pull it up with my tractor bucket, that didn't work so I attacked it with a sledge hammer and couldn't even crack it. A backhoe struggled but did get it up.

bosch sds max will make 1 1/2" holes,,, cheaper & faster ? rent bosch brute 60# for breaking,,, seems to me your bigger issue is funding this work

...and the age. Concrete continues to harden for many years. It's much easier to drill new concrete vs old.

Breaking up concrete is never fun. Years ago I did a patio tear out where the slab was tied in to the foundation. We cut back the pad with a wet saw to get a straight line along the foundation, then we started breaking up the 4" slab only to find another 6" slab under it. At that point we called in the machine ops from down the street to have at it with their excavator. Half way through pulling up the 4" and 6" slabs they found another 8" slab under half of the patio! I'd still be there to this day chipping away at all those layers if we didn't bring in the excavator.

Done! I rented a makita electric jack hammer. The bottom was easy but those sides were a major pain! They turned out to be about 2'. Took me 7 hours but I finally got it.

Good job. A little concrete will never be a obstacle for you again. :wink2:
