The concrete won't affect the plastic but use some hair felt and it will accommodate any expansion in the pipe http://www.ebay.co.uk/itm/Hair-Felt...2mtr-New-/121201318122?_trksid=p2054897.l4275

You should use 50mm when entering a concrete floor with basin waste, shower waste pipe etc.
And use long radius elbows where direction changes.
That will reduce the chances of blockages and easier rodded.

Solvent weld is a better option also as it reduces the chances of a joint being de-coupled when pouring commences.
