Replace short run of cast iron.

[MikeFromHC]

I have to replace about 30 feet of cast iron pipe. Most of the run is under a thin concrete and and a digging bar makes "easy" work of it.
There is however a short run of less than 10 feet (that may not be straight) which is under four or more inch concrete.
Is there any way to do a "trenchless" replacement.

Just get a Bosh Brute and bust up all the concrete. It is easer and cheaper.
