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 :confused: 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?

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?
