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!
