Breaking Rocks

[RollTideRam]

I'm in a 4wd club. We use a clubmembers property to have a Rock Crawling event. We wanted to make a easier access road for a concession stand and to remove broken vehicles easier. I don't know the name of the stuff, but we drilled holes with a hammer drill, poured in the expanding grout. This stuff is amazing. Went back with long steel rods to help move them around the next weekend. If we had more practice on our drilling technique we could make gravel out of the whole hillside. The drill bit and the grout were about $200.
It works overnight in warm weather, but we worked in January to avoid the poison oak easier, and it worked in about 3-4 days. JC

The easiest way I know of to break those puppies is to lift it up and drop it. If you can only lift one end then lift that corner and place a stone under it, then drop it.

They appear to be a sandstone type stone and will break easy this way.

A good hammer drill and wedges will also make quick work of it too. I use a twelve inch Stihl with diamond blade and it'll go through them quickly.

But if you want to break them try to move them without breaking them. It works almost every time. /forums/images/graemlins/grin.gif

Thanks for all the good ideas, will have to try the droping on harder rocks first(cheapest) first. Most of them I think I can lift at least one side. But it will be awhile before I can try it, the area is all mud now. /forums/images/graemlins/mad.gif

you might want to look at the cost for renting one of the chain saw type cutters, they work pretty good I hear, also vote for the scribe one side and flip it dropping it so that one edge has the scribe down then you drop it onto one other stone or support step. that way the scribe line is unsupported, and if it don't break along the line then a wack with the bucket might perswade it to go...

This is what I was going to suggest. Typically they are callled "feathers and wedges". The ones I have use a 1/2 inch hole and about a 3 pound hammer. Very easy once you drill the hole.
