Running a DPM up inside the cavity?

[Frankieboy231]

I have an internal floor that is significantly lower than the external ground level. Still designing so:
1) with a cavity wall full of Rockwool, can I run the slab dpm through the internal leaf (into cavity) and up to internal wall dpc?
2) would this be ok with BCO?
3) does anyone know of a diagram somewhere - 3hrs. and I can't find one..

any other suggestions on how to fixit?

Thanks for looking - grateful for any advice..

OK, just found an old thread on this subject so answer found ... just got to manage to get in contact with BCO to confirm nothings changed and still ok.

Subject dead now .....
