I have a 110mm soil pipe horizontally through a 160mm hole in a brick &
breeze block wall.
Anyone guide me to the best way to seal this with the wall?
Do I use ordinary brick mortar, concrete, flexible mastic type sealant or is
there something specific I should use?
Thanks

I'd just use ordinary mortar. Should be fine. You could always apply
mastic around the mortar/plastic interface afterwards, should there be
any gap there, but there's no reason why there should.

Squirty foam and a plastic trim (or render/mortar) on the outside.

Think about fitting a sleeve first. 150mm soil pipe is ideal. That would
be mortared in permanently. The 110mm soil pipe inside the sleeve doesn't
need much,
something flexible to accomodate movement. I would use an oil based mastic.
Certainly not concrete.
