Yes as you said i focussed on the distance i needed from the wall to best accommodate joining to the inspection chamber (which i havent yet done and today is a washout so will likely do midweek)
So i got through a barrel of work yesterday but finally managed to get concrete down. The fall I ended up with in the end was about 1:45 or 1:50 so happy with that and alos did the water leak test and not a drop lost over a full afternoon which was good enought for me. So i did the double layer of DPM, through in as much tec 7 as possible to stick to the old membrane (for what its worth) and got my rented concrete mixer up and running. About 200litres of concrete later attached is the result. that is a week of my life I am never getting back!
cant thank you enough @Hugh Jaleak for all your guidance over the last week. Been a really great resource for me that got me out of a few decision-making rabbit holes. You are very generous with your time and am really appreciative.
