Building a Backyard Arch. Follow up post to yesterday. This was a few years ago. No leads or strings. Just laying with a level. If I wanted it to be perfect, I could have set it up that way. But frankly, fun to freehand it. Feels more...artistic, and less scientific, this way. Note how easy the arch is! Put up formwork. Lay the brick over. Take formwork out. The arch is the shape masonry wants to be in; it keeps everything in compression. No steel or anything else necessary. This has literally been done for millennia. It's crazy how often the modern world (in the US) wants to complicate this. Make the interior concrete block, add steel and lintels, use metal ties to attach face brick....crazy!! Just build the dang thing out of solid brick. It's so simple. No need to complicate it. Lots of people asking about foundation. SUPER simple. Just a concrete footing. In Oklahoma that's just 24" deep. Did about 28" wide (with a 16" deep arch). Key is to do a continuous footing across, including below the opening, with rebar. Otherwise you can get differential settlement and it will crack. With this, even with movement, the footing moves as one piece, and the entire structure with it, so no cracking. Also, to answer another question, this is extremely heavy. Like 5,000+ pounds. Not going to blow over. Kids can climb all over it. A tornado could knock it down, but otherwise you are totally fine. Can you do this yourself? Yes. I'd start with laying a small wall to get used to the feel. But have had college students come down and build things like this over a week with zero prior experience. Main thing is it just takes them a very long time, and may look a little crude, but still beautiful.
