Hello,
Any chance you could let me know what you did with the basement flat floor in the end?
Have the exact same situation. Considering limecrete with ASHP + UFH. Bodge job of waterproofing performed historically with membranes approx 1.5m above the floor level. A couple of the walls retaining soil.
Thanks in advance..
After getting your notification, I have headed over here to my "profile posts" page. I don't get many PM's but I have noticed that most of the ones that I have received over the years have disappeared. I now only have 6 listed, going back to 2010.
I still have the utmost respect for you, honest.
