Concrete? 
won't react with cable or anything, shoulda mentioned that was what I was worried about, like with plaster and t&e
Put them in some sort of tube or ducting, so it can be replaced without ripping up the concrete should anything ever go wrong with any of the cables, or something else superseeds them in the future
im putting extra in to start with, so no, but if it is likely that i will end up with a problem then I will, and if i do, then i dont need to worry about anything reacting with the cable. 
ok, some old hosepipe 
any alternatives to concrete like i remeber reading you could fill concrete with polyfilla(or am i going mad)

Are you cutting a trench in an existing floor. then laying cable and back filling the trench with concrete ? If so then you need to consider whether the strip of new concrete is strong enough to resist any loads without cracking. It is unlikely to be strongly bonded to the old concrete.
If the sides of the trench are vertical then the concrete strip under pressure from a chair or table leg may deflect, snap and crush the cables.
If you must avoid conduit then cut the trench wide enough to have at least a inch of clear space on the floor of the trench either side of the cables. Then pour the concrete ensuring the cable do not float up. The concrete either side of the cables makes a "wall" of support for the "roof" over the cables
ok, will use conduit then
