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..
