This has probably been asked but I couldn't find it....

Tying into existing PVC under basement slab for a new bathroom and wet bar in the basement. Running 2 inch PVC to the wet bar and don't quite have 1/4 in/ft slope under slab and would need to run about the last 2-3ft to get to the bar through concrete (horizontally).

Do I just need to sleeve the portion of the PVC going through the concrete?

How thick is this concrete? The way I'm picturing this, you'd have a weak spot in your concrete.

Can't you pop up early and pipe horizontally above the concrete?

I cant pop up early because that would necessitate me moving the wall. Concrete slab is standard 4 inches thick.

If possible put the last 2-3 ft under a cabinet or somewhere where it won't matter. But in general I believe you can do what you propose, you'll be interfering with (displacing) the concrete for under an inch of height. You want to separate the PVC pipe from the concrete with a barrier of compressible foam similar to sill sealer. (In fact you could just spiral wrap the pipe with sill sealer.)
