We have oaks by an easement with roots growing under a concrete walkway. I've cleared multiple times the top 10 to 12 inch layer with a Dewalt electric hacksaw, probably went through 60 blades of various kinds as inevitably there are chunks of concrete at depth, rocks and who knows what else.
Perhaps once in 10 years or thereabouts, city comes and rips up sections of the walkway, excavates the roots ( think "Gold Rush" ) with massive dozers, re-pours the concrete and generally leave the area looking like a vision of a war zone. It takes years to recover the ground aesthetics even with resodding.
That is why I prefer to delay the destruction by City crew for as long as I can but am thinking I may be using the wrong tool or blades.
If there is a simpler and safe way to cut along the edge of the concrete (about 100 yards in length, not just one spot), suggest away.
