Bracing of elliptical stair risers and placement/finishing of concrete. For all the hates out there saying how this was gonna float, break, bulge and spill everywhere.. y’all can take a long walk off a short pier! 🤣JK! Curves are strong and when placed at the correct slump, you can still get a nice finishing and not make a huge mess. And FYI, I’m not a finisher. I’ll place concrete and finish footings and walls. Flat work is another animal/discipline all together that I have huge respect for. H
