soil pipe in concrete

[thenewestguy]

Hi there, just looking for a bit of advice, can a plastic soil pipe be laid then abour 250mm of concrete poured over it? there will be no blocks laid on the concrete, just a row of slabs? would this be a big nono or pretty acceptable? any helps great thanks

all pipes beneath paved driveways etc. are encased in concrete.

so it should be ok? and any joints surrounded in compresible aggregate?? or just straight forward c35 concrete

 

[noseall]

where exactly are these pipes located?

250mm c35 concrete for a row of slabs be it a driveway for a sherman tank? or an extension

should be no problem.
Just be aware that plastic pipe can float up in the concrete, so should be ither weighted or anchored dow prior to pouring the concrete
