Toilet 100mm soil pipe under concrete floor

I was put off by some negative feedback related to Saniflow toilets and I thought I need to avoid them at any cost. After the works, the bathroom will be 1.6m x 1.4m. It would be tough to have toilet, basin and bath (or even shower).

Btw why is this is an issue having a basin in the new toilet. I thought the waste from the basin will go to the toilet soil pipe rather than having another 4 meter pipe for basin.

Sorry when you say the concrete breaks out you mean I cannot do it because of the foundation issues? I am not sure how you can put such big pipe under concrete from outside. Is it doable for a 4 meter pipe?

I said "put it in trench", you only need to tunnel for the 2'6" or so under the footing or edge beam
