Shower waste exiting at or under dpc

[sparer]

I will be fitting a shower into a bathroom and want to embed the waste pipe into the floor. This will mean that the waste will exit the external wall either in the first or between the first and second blue courses. Is there anything wrong with this?

Thanks

Not if you reseal the DPM.

It's a 60's bungalow woody. Don't think there is a DPM.

Then it won't be any worse.
