Hey, I’ve got a cold room in my place that is concrete on all sides, I’m going to be framing it in and insulating and I don’t really need any help there unless there’s anything cold room specific I should know, however.
As you can see I have a floor that appears to be a stepped concrete pit, filled with quite a lot of dirt, and what I believe is probably a tie in to the sewage drain.
Can I just get rid of the dirt? The whole room spells like petrichor because of it.
Assuming the pit continues to step down, can I just build the floor over it regardless, and do I need to support the pipe in some way if the dirt is removed?
Or, if I’m completely off base please let me know what I should be doing.
Thanks


Where are you building? I’m assuming this is the basement or the ground floor. What is the rest of the subfloor on that level?
Wood resting on dirt is a big no, so that is an obvious red flag. Whatever floor you put in, I’d preserve your access to that clean out. Once you answer my Qs above, I can help give you a recommendation.
Basement yep. The rest of the basement subfloor is poured concrete. Other than this cold room the basement design seems to be very typical poured concrete foundation dug under grade, typical of eastern Canada.
