Jack Hammer help

[Riodog]

I need to get a demo-hammer or whatever to bust up some concrete footing and blocks. Anyone have any advice? I know nothing about these and don't want to wind up with something that I won't ever use again. I have a couple of hammer-drills but they don't git it.
Thanks,
Rio

just rent a electric jack hammer, if you have alot to do then rent a 90lb air jack hammer with a screw type compressor. price around most rental yards are slow and will compete on prices. either way its hard work.

Unless you are breaking apart anything thicker than 4" go with the 60lb electric, if thicker go with the 90lb air hammer.

If you are thinking about purchasing one for mild demo work the 30lb. Bosch always worked well for me.

When you say footings and blocks. what type of footings and blocks?

Are to taking about a foundation for a existing stucture? if so can you get to them from the top or is it going to be attacking them from the side, maybe even underneath a house? Do you need to remove the entire thing or just part? how big is the job?


We really need to know these before we can direct you to the right tool.



If you are working under neath a house, spend the extra bucks and rent a hydrolic hammer, instead of a air powered one. trust me

I'd rather use a weak 25 lb electric then a air powered hammer in a crawl space any day of the weak.

What it are is -> the footing and block wall of a planter that runs about 3 feet high, 1 block thick, and 80 feet long. I can hit it from both the top and side.
I was looking at the Bosch 11227evs but didn't know if it was big enough.

You're using a jack hammer on a block wall? Cinder block? I may not understand the type of wall you describe.

I have a concrete breaker for my skid steer (just a big jack hammer attachment) but I've never used it on a block wall. You can drive slowly into a block wall with the bucket down and it will fall over. It won't stay together, either. It will fall into chunks of, at most, a few blocks.

I'd rent a skid steer and a trailer and you should be able to have that wall gone in an hour.

Hit up Home Depot for a 20# sledge, the biggest demo bar they have, then rent a mexitool on the way out of the parking lot.

While that would work, it would be a little small.

Have you tried the "hit test" yet?


you know you take a 10-15 lb slegde and take a couple swings( you will break off the block as its really weak). If it sounds solid, out the hammer bounces, its breaking hammer time. If not, keep going. Some times a slegde will be faster then a breaking hammer.

Anything is going to break the block out, as its really just a concreate form, its what is in the middle.

Just pray you don't find a bunch of bar... that makes life fun...

if its a block wall that changes everything. if it has a footing rent a mini x with a blade and a thumb pull the block over push into a pile pull the footing. use the bucket and thumb to load and the blade to cleanup then you can level the existing dirt to your liking or anything else. no back pain when your done. go to the river pop a cold one.

Some of these Bosch units have maintenance timers built in and will shut off at 500 hrs or so, ready to be taken in. Just an FYI.

Not that your going to pile that kind of hours on this project.

If it was a retaining type wall the footing will be a minimum 12''X12" and have RE-BAR Get a 65lbs bosch elec hammer with a chisel and a point and hopefully you have a torch for the re-bar. If no torch you will wind out with a very long piece of broken concrete all tied together by 2 lengths (or more) of #8 OR 9 re-bar. If it was done right! You could get lucky and have a backyard weekend wall and it will break up with the hammer. I did demo for 15 years and you never know till you get into it.

Thanks buddy, I appreciate the offer.
All great advice. I always know where to get the answers.

The block wall is a retaining wall-> planter. Filled and rebarred. The pool, decking, and other bs is just about done and this is the other side of the yard. Long story short is it will prolly be a 6 month project. I have the sledge, the bars, but not the 300 lbs or the energy. lol. HD parking lot here I come.:skull
