In response to Re: Cracked waste pipe under grade slab

The best way to cut concrete is with a Concrete cutting Wet saw with diamond blade. Next would be a jackhammer. Both of these run on 120 volts. I doubt that you have rebar in the floors. The best bet is to hire someone for the cutting. It's very quick and painless that way. There is a bit of art to removing concrete without destroying what is below the surface. With the Jackhammer, I rest it on my leg and am ready to pull the hammer out if it starts to sink to low. Terry: After cleaning out the waste lines I found a crack at the bottom of the waste pipe near the tub. when I snaked out the vent pipe I found dry dirt. They are 50 year old galvanized pipes. The run is about 22'. I want to do the labor so the plumber can run pvc and finish the concrete. Do I need a concrete saw and a jack hammer? How do I use them? Will they run on house current? What about the rebarb, do I need to replace it? Please help me through this terrible mess.
