Breaking up is hard to do - Concrete fence post footings

Drill holes in a line. This is an approximation to sawing. Imagine how you would saw it apart. Then place the holes accordingly. Once you have the line, a rock chisel will be far more effective.

Drill holes, then wait............

Drill a row of holes, where you want it to split, then use the method they have used since Egyptian times - hammer steel wedges into the holes, to gradually force them to split..

Didn't realise the Egyptians were adept at alloying iron and carbon..

Problem circumvented

After drilling a few speculative holes I have given up trying to break these damn things apart.

So far I have managed to load and dispose of the two smaller beasties - just the large one to go. I used a ramp, some chocks and muscle power to roll the lumps up into the trailer

Thanks for all the suggestions
