Copper pipes in concrete floor

Hi,
I may have to run a new set of downstairs pipes for my central heating and they will be in a concrete floor.
It looks like I have a leak under the concrete somewhere that I can not see so I think I may start with a new set of pipes.
What is the pratice for laying copper pipes in concrete?
Aoes anybody know of infomation about this I can look up?
I think they have to be lagged to protect them from the concrete but which type of pipe lagging is it?
All I seemed to find on the internet is the normal foam sleeves.
Is the lagging the same as the pipe lagging in the loft or does it have to be a special one for concrete?

Not a quick answer and there's plenty here - do a search.

I'm having problems finding anything from a search of this site.
Either I'm searhing wrong or there is nothing.

Try eg burying
