What is ‘superadobe’?

“For me, it’s fascinating to have a superadobe home, above all because of the architecture and the use of earth, using local resources,” Saavedra says. Saavedra and his family are the beneficiaries of materials and instruction from the Mexico City-based architecture group Siembra Arquitectura, which aims to provide people made homeless by the earthquake with the knowledge they need to build structurally sound buildings. Adobe and superadobe production both involve mixing materials and then stepping on them – with the help of horses, in Hueyapan’s case – in order to fully compact the mixture.
