Micro Bore 10mm pipe in concrete

[marlb]

Hi,
Can someone give me some guidance?

I am going to add a radiator to my micro bore, sealed central heating system. It is on the ground floor which is solid concrete. The current rads downstairs a fed by pipes that have been channeled into the concrete floor. I am going to have to do the same for the additional rad. How do I seal the pipe from the concrete as concrete will corrode the pipe? also how deep do the pipes need to be?

Use plastic sleeved pipe, You are restricted to the depth by the water membrane under the concrete floor.

Cheers for the advice. With regard to depth - can I go down maybe 1 inch or so and then screed over the top or do I need to go deeper?
