You're right and the one product I have used is Dexpan and there is one other, but it you Yahoo/Google it you will find what youre looking for.

Not cheap, but good stuff.  I broke apart my porch slab that was a "hunk" of concrete and it took about 3 holes and a gallon of the liquid breaker to take care of the porch.  What a good time that was.  The hunk was about 5'x3'x4'.  The breaker busted it up in no time.  I finished it off with a prybar.  Enjoy.

Wedges and feathers work just as well. And you are not buying material that you are just throwing away.
