Hello everyone,
we have received our detailed construction plans. The issue concerns the drainage of our kitchen. Underneath the kitchen is our basement living area made of waterproof concrete. Now, the drainage from the island with the sink is planned to be routed downwards into the basement room below (which is a living space because it’s a basement living area) and then further to an exterior wall, from where the pipe will be brought down from the ceiling. I hope I explained it clearly?!
I find it quite unattractive to spoil the nice living space like this, since a 10cm (4 inch) pipe will run across the room, and then the pipe will also go down along the wall from the ceiling and will need to be boxed in.
Is there no more elegant solution, or does my builder just want to choose the cheapest option for themselves? My layperson’s opinion would be to place the drain pipe inside the ground floor ceiling and run it along a room edge before going down. From what I understand, I can’t avoid the boxing-in in the basement due to the waterproof concrete?
Thank you in advance for your help.

We also have a living room beneath the kitchen. In our case, the construction financing arranged for the wastewater pipe to run within the watertight concrete (in-situ concrete basement). However, we do not have an island in the kitchen, so I cannot provide information on that. The wastewater pipe in the wall was not an issue, but if you have agreed on this with your construction financing beforehand, I would recommend having the pipe marked on a plan. This way, it won’t be accidentally drilled into.
Best regards

It could also warp under the screed and then extend down into the basement.

Thanks for the feedback. As I mentioned, it would already help if the pipe could be moved from the center of the room to the edge and then down. But for that, it needs to go through the wall in the ground floor ceiling, so into the screed. I’m not sure if that’s feasible; I will inquire about it.
@ypg – you mean me when you say "a lot of time." But I agree with you; we did discuss our floor plan a bit. As I said above, we are currently working on the detailed construction plans and the problems described there.
Does anyone else have any ideas on this?

Caspar202026 Apr 2016 10:44You do know that a pipe needs a slope, right? You should calculate about 1cm (0.4 inches) drop per 1 meter (3.3 feet).
But why are you using a 100mm (4 inches) pipe for a sink drain? Is that just an assumption, or is it specified in the construction plans?
Usually, a 40mm or 50mm (1.5 or 2 inches) PVC pipe is used. Or is it a butcher’s sink?
If the pipe is oversized, the water cools down faster, which increases the chance of clogging because the grease tends to solidify again.
Also, how far is it from the center of the drain to the wall? What material will the ground floor ceiling be made of, and what does your floor construction on top of it look like?
