Hey guys. My grandpa is removing some concrete and dirt to put in a slab of concrete. The concrete is a little narrower than a sidewalk. It's a like a dual tire path for a car to his garage. The area is about 20 feet long by 8 feet wide. Now, that's quite a bit of concrete and fill to move to make way for the slab. I have a couple questions, actually. First, how deep should i dig down for concrete? I was thinking about 5 inches, should that be sufficient for a slab? Second, what kind of equipment would you suggest? I was thinkin a mini-X, but I'm not sure if I'll clear the sideboards of a dump truck. The excavator I had in mind was JD's new 27C ZTS. My local rentals just got it, along with a new Deere 240 skid steer and a JD 110 TLB with thumb on the backhoe. I thought about taking a hyd hammer and busting up the concrete with a skid steer and then switch over the to bucket to load the chunks into the truck. The mini x doesn't have a hammer, so I'd have to lift 700 lb sections of concrete 9 feet high with a mini x, which I don't think it will handle that. My grandpa wants to do this the most cost efficient way, so I figured I'll trade something for the use of a dump truck. I haven't been able to find anyone with a dump insert in a P/U so that's out of the question, otherwise I wouldn't have this problem. Any ideas guys? Thanks!
