Is it ok to put pipes under concrete

Leif

I think the problem was that they did not know that cement corroded copper, hence they buried copper pipes in screed.

Not usually corrosion, mostly due to the movement by expansion and contraction or the pipework wearing a hole in the pipe from the aggregate in the concrete;)
ANY pipework in domestic situations MUST be lagged correctly to allow for this:)

You can get Sulphate Resistant Cement(SR), which I have had previous experience of with MS pipework in commercial situations, but, even with this overtime wear will occur, and its usually just a sharp piece of aggregate touching the pipe that eventually wears its way through:mad: a pain in ther bum to find and repair, especially on 3" pipework :rotfl:

Use 10mm plastic inside plastic conduit to each radiator, so no joints are needed in the floor. A manifold will then connect each circuit.

Cement will eat away the copper wherever it touches it and the expansion/contraction will just speed the awaiting disaster up.
