drain lines under slab


Do you put anything in trench, ie; sand etc. to support drains lines (not supply lines) in a slab foundation?

#57 stone is what I use.
Just using the soil you removed is going to settle over time and the pipes going to move.
Sand is not compressable.

I use sand or pea gravel- both offer good compaction. Be sure you don't lift the pipe while bedding- it's very easy to do

No disrespect meant but pea grave is rounded and will just move, not what I would use to hold a pipe in place.
Just step on it and it moves and you sink.
Ever seen a pea stone driveway? There's a reason why it's not used for that.
Works fine for landscaping but that's about it.

To each his own Joe- but its the flavor of the day around here. Delivered right to the ditch line in a mixer from the batch plant if you want it that way.
We also use fines from the pit if you want something sandy.

Down here we use sand or clean fill, pea rock outside the foundation only, mainly in the lats.
