I need to break up a 20x13 concrete slab. I am assuming 4" thick at least - it was a driveway. What kind of jackhammer should I rent? Any idea how long will it take? How are they powered? Air? Electric?

I'm no expert but the big jackhammers require a tow behind air compressor (BIG ONE). Home Depot rents some electric Hilti's that may be big enough, it may take a while to bust up something that big though. It may be cheaper and easier to find someone with a backhoe to come in and get rid of it for you. Probably would take them more than two hours tops.James -
Bin there, done that, Thats looking for a heart attack. Check for any contractors working nere yiou willing to pick up a few extra bucks. You got to get rid of that stuff after you brake it up and a contractor can get rid of it. I learned that lesson a long time ago.

I helped a friend do something similar and he knew somebody that had a big jackhammer. Even though the JH is needed, it's still a tough job. Then handling all the pieces to go into the dumpster, what a job.Originally posted by crokett
I would contact someone and then weigh your costs; rentals, dumpster (make sure they take concrete), bad back, time ...Brian

Crokett, I recommend 2 options:
1. Rent the equipment and find a few college kids home for the summer.
2. Contract it out.
Running a jack hammer sucks. It will beat the snot out of you worse than any other job I can think of.Comment

the situation is a sloped drive that I am going to level out and turn into a patio. So the concrete won't move except to the deeper part of the slope. then it will be covered with 20" of dirt.
So sounds like I need a big compressor along with the jackhammer. I will call the rental places and see what the $$$ are. A backhoe would take care of it, eh? I know a guy I can call.David

Can you rent a bobcat with a ram and a bucket? It would make short work of it but may end up costing more.spellling champion Lexington region 1982Comment

A bobcat around here is $184/day and the hydraulic hammer attachment is $160/day. Might be the best $350 you spent...Comment

Did you consider one of those expansive demolition agents? According to what I read, you use a hammerdrill to make a series of holes, mix up the compound, and fill holes with it.
