in my experience its always been a grinder with cutting disc, then chisel/floor breaker, very messy,hard work and a no no in an occupied house because, the dust and noise will be there for weeks after, suggest you use plastic cladding and hide the pipes in that,  |

Hi Tom many thanks for your input but for me it will hard going back to my customer as he wants to put french doors where the one rad is that needs to have the pipes moved and I must say his house is very plush in very good decorative order they have a 2 1/2 little girl and another on the way......... how do you explain that to the customer ..........suppose I can only tell him how it is ........   |

Angle grinder like Tom says. The dust is atrocious. Wear a mask

I've laid, and broke up, a fair bit of concrete over time. As Tom says, cut a nice straight line, then clear it out. You could hammer and bolster it, but chips flying off, (hitting all the plush surroundings), ridiculous time and effort needed, is a no no. You will need to dig deeper than 15mm, if you don't want the pipes to chafe and leak.... Tell the customer how it is. If they balk at your recommendation, best leave the job alone. They'll have you making good forever and a day. |

Many thanks all for your thoughts but at the end of the day there was nothing I had not thought about just wondered if anyone had any real good tips or short cuts but in my heart of hearts I think I know what I have to do tell the customer how it is then  Otherwise I think I will be in it up to my ears  Many thanks Guy's |

For one off use no professional will spend loads on a tool unless the customer pays for it!! |

Yes they're a handy little tool. Used one a few years ago. Great for turning everything in the room white! You clean up, and 10 minutes later it's like it snowed again.
