Yards are hard for me. I could ask the guy tomorrow what the number is. On my invoice he put it in sq ft- probably for dummies like me to understand. It’s a 116’ wall, 8” thick, like 3’ high with “spot footings.”
And 1800 sq ft of flat work with a little curb in the back.
I am going to need some flat work done this summer. Did you like your guy? Reasonable pricing? would you PM me his contact info?
