The guy repairing the neighborhood sidewalks cut my two sections in half (they were already cracked along the line at the two ends).
Last year I got my neighbor and when he lost interest, a friend, to help me lift up and flip over onto 4x4's each of the cement sections.
I cut out a lot of root, but not enough, and one section looked great, but the other no, when we put them back.
BUT THIS YEAR, neither guy was enthusisastic so I did it myself, with 4 5-foot 2x4's, 4 8-foot 2x4's, 5 pieces of wood for fulcrums, and one 4x4 fence post for a ram, to move a fulcrum when there was weight on it. I didn't flip it over, just lifte it up and wiggled it to the side.
Took maybe 45 minutes, plus 30 minutes to chisel out more root**, and 30 minutes to put the slab back.
It's amazing what one can do by himself with the right tools. "Give me a lever and a place to stand and I will move the world." I forget who said that.
**Maybe I should just cut out the whole root. But I'm still thinking the tree gets some nutrition from the half-section root, and that it might die without that or the other two trunk roots that I trimmed last year.
