How to shutter existing waste pipes correctly?

[Rott]

Hello,

Im building the extension, and my existing waste pipe goes through middle of my foundation. I need to keep it due to the drop, house on slope. I can only find build regs how to bridge over pipes penetrating wall. Any info how to do the ones in the foundation correctly? Shutter and bridhe? thanks!

Yes and close off the ends with compressible material

Is that the way to do it? As im planning to pour the foundations Tuesday.

The bridge would go across the pipe after the pour, it looks like yours is going along the pipe
