My first concrete slab demos. 2 slabs about 4-6 inches thick average. First one was 100'x20' with curb and a number of poles concreted into slab and ground and cut off at slab. The other was about 40' x 50' Pics are of first slab. Never did it before so I punched holes with a 500lb hoe ram after I made my little grid then broke it up with my industrial grapple. Was out there 2.5 days including loading the tandem 10 times. Had a lot of trees to cut, stack, and grind stumps so it wasn't all concrete breaking but I think it turned out pretty clean and ready for builder to figure out where to put new slab. I usually don't do this type of work but I do all these folks trees so I didn't another contractor coming out and ramming trees. I was amazed at how strong my little bobcat s330 was when handling the concrete with my 74" CI tooth bucket and the 66" industrial grapple. It has some power and felt much more stable than my 272c and s300 did. That little extra weight makes a difference. I also found out that sharp teeth on a bucket will cut rebar!
