Hi, I need to put my soil pipe through my exisiting wall under my suspended floor (first few rows of brick), but underground both internally and externally.

Internally, the soil pipe runs tight to my wall. What's the best method of getting the soil pipe out?

Do I need to drill the hole big and sleeve it? If so, what size would you reccomend (110mm soil pipe).

Do I need a rocker pipe set up? I might struggle with this as the elbow will be so tight against my interall wall.

Or can I just drill the hole 110mm and seal with flexible sealant?

Thank you!
 
Just drill a 110mm hole and seal any gap with foam or whatever depending on the hole size.
You don't need to sleeve it although a slightly bigger hole and foam will do that.

Thanks for the advice! Because my soil pipe is so close to my internal wall, the socket part of the soil pipe will be inside the wall, so will have to core drill either 127 or 152mm.
