Hit the 50 pound mark on my subfloor pour and it totally changed my approach

I was doing a small bathroom remodel in a 1960s house and the subfloor was trashed. I figured I'd just pour some self leveler and be done, but I ended up needing 50 pounds of it for a 5x7 room. That number caught me off guard because I always underestimated how much material actually fills the dips. Now I always overestimate by at least 20% just to be safe. Anyone else get humbled by a concrete pour that seemed way too small?

50 pounds for a 5x7 room? Man that is wild. I did a similar size pour in my own place and went through almost 80 pounds before the dips stopped swallowing it up. The house had settled so bad in one corner I think I could have poured a whole bag in there and still seen a low spot. It really changes how you think about those little bags when you realize how much material it takes to actually level things out.

Oh man, do you think the house settling was worse because of the age of the foundation or just the soil underneath? I'm always curious what causes those deep spots.

Whoa, 80 pounds for a bathroom? That’s insane, man.
