LEAP4 Project, Diepsloot, Johannesburg. Preparation of on-site material for stabilized rammed earth (SRE) construction. The correct mix design is an important component of a successful SRE project. The correct SRE mix is placed in pre-prepared formwork. This is a labour-intensive process, which adds to skills development and job creation. Formwork is removed after compaction of part of a wall section of the new LEAP 4 school. A completed SRE wall section that shows the interface with conventional brickwork and the flexibility of this construction method. A close-up of a typical wall movement joint and boxed-out window opening. The aesthetic appeal of SRE lies in the subtle variations in natural soil colouration. A freestanding wall section with new formwork in place for adjacent panel illustrates a typical sequence of construction. A completed curved wall section with brickwork for lateral support in place illustrates the structural stability of SRE. The natural internal brick and SRE finish enhances internal temperature and humidity control, which is ideal for safe public spaces.
