There's another thread going on about best way to dig 3' of bedrock. This is similar, but different enough that I didn't want to derail that one.
I have a (let's say 3'-4' diameter) boulder that got dug out when I built my barn. Not sure what type of stone, but seems pretty dense/hard. Excavator was able to roll it, I was able to push it against a tree with my 8000lb tractor and that's where it lies. I think that if I could split it in half, or more, I might be able to lift the sections with my FEL.
The other thread introduced me to Expanding Demolition Grout. Seems like a good option, but how do I drill holes and not end up spending $500 on a rock? When all I get is.... more rocks.
What type of drill? Type of bit? Bit diameter? How deep? How many holes? How far apart from each other?
Any way a homeowner can drill with a 1/2" electric drill? Would grout still work. Any experience? Guessing my chances are probably slim to none.
What do I need for a rock drill (or whatever)?
The Dexpan site (How to use Dexpan to break concrete or rocks easily?) say 1-1/2" bit, holes 1' apart, 80% to 90% of depth.
80% to 90% depth of a 3'-4' diameter bolder seems excessive and needs one heck of a bit.
Any way to cheat on the cheap? What's my options?
