I have found where the slab is leaking. I have read the advice concerning how to find the leak and then to jack hammer the floor to expose the pipe. I know this sounds dumb but how do I jack hammer into the slab without accidentally hitting the pipe?

The pipe will be located well below the cement pour. Not to worry. You'll probably have to dig down to it after the cement's removed. Before you can solder in a repair ALL the water and moisture must be evacuated from the pipe to be repaired. Good luck, Tom
