Here are three photos from different angles, showing both layers of reinforcement installed. As explained in the previous post, a continuous beam requires double‑layer reinforcement.
The red dot on the threaded rod marks AISI 316 stainless steel, which is acid‑proof and chosen for its durability. I didn’t cut corners on materials — stainless rebar, glass fiber rebar, stainless vent pipes, everything top quality.
This project is not only about building a double‑vault composting toilet, but also about experimenting with reinforcement techniques. And yes, I filmed the ‘outhouse jam session’ too, because such a build deserves both seriousness and humor.
