Thanks BigWallop for these great tips.

The house is 15 years old and the pipes are copper. The pipe that I
think is leaking comes out of the ground with an insulation tube or
foam around it. Other pipes are coming out bare but have green oxide at
the bottom.

When the pipe is repaired would the floor of the room dry out and how
long should it be given before I cover it again.

Do you think this is ok to tackle for someone with basic skills in DIY,
I have put pipework for a shower unit in years ago and it is still ok.
Once again I would like to thank you for your kind advice.

Firstly, the green stuff you see on the pipes is corrosion, and this means the
other pipes are in need of replacing as well, or new pieces set in where the
minerals from the concrete have attacked them at least.

I honestly think it would be better for you to cut out the whole lot of the
pipes and replace them all inside a proper duct system which doesn't allow the
new pipework to come into contact with concrete at all when the repair is made.

The concrete should actually dry quite quickly once the source of the dampness
is removed. Any moisture left in will be soaked up by the new mixture you lay
in, as the mixture doesn't need to be soaking wet when you make the repair to
the floor. The only wetting time is when you come to polish the surface to make
it smooth again. That's left until you see the concrete surface turning a
lovely pale shade of green, which you'll see when you start the repair, and also
gives it its name of being "green" when not totally cured.

So, it's now up to you. Do you feel up to the job of replacing all the pipework
and concrete you remove, before you get more leaks on the other pipes?
