Big Rocks

Emo

I'm doing a fence job and it looks like they used a lot of rock for fill. I can go about a foot down and then I hit rocks to big to get out. Will a electric jack hammer work to brake them up. Some are about 6'' thick.

I suggest some dynamite

It doesn't sound like that is going to be a pleasant job. I'd go back to the person who hired you and tell them what you've got going on there. I wouldn't even touch it. You don't know what's down there.

Post was big rocks, so I thought I'd bring mine in, just to see it was about.....rocks.

If your contract doesn't have a rock clause of some sort..or you didn't bid the job based on the possibility of rock.....suck it up and finish the job.

If you do have a rock clause..go back and mention that there will be a change order based on time...

Either way....in my experience...the electric jackhammer will work but not as well as an air hammer....

I just did a job that I knew would be rocky....we dug almost 50 holes this way..of course it was part of the bid.....

Good luck

If you are going to be hitting rocks all the time then get a big air hammer... If its just a few then the electrics will do alright. I own the hitachi h65 hammer for when we find rocks we just break them up and out with that. And most of the time the rocks I hit are granite so it takes a couple minutes with the electric.

I put the first panel up and have 7 more to go. The rocks are about 12'' or so and partly in the holes but too big to get out when deep. I gust need to chip them back from the holes. I was hoping a Elec. would work.

I would go with the electric... You could use the 60-80 lb range and they would work fine... If you want to be able to lift it out of the holes then the 40 LB range would still work just take a little more time.
