Loam is produced by the natural weathering of rocks. It can be found almost everywhere and is considered a local building material – even on the Upper Rhine. It consists of different rock or particle sizes, from sand to silt to clay. If dried loam is combined with sufficient water, it becomes plastic again and can be brought into a new form.

In a joint seminar of the KIT Professorships of Sustainable Construction and Building Technology, a small rammed earth garden house is currently being built near Freiburg. After the material has been tested and suitable formwork has been built, the clay is currently being brought in and compacted.

The students received the basic and background knowledge in advance and currently have the opportunity to gain practical experience in this construction method under adapted conditions, to obtain technical know-how and to experience the materiality of rammed earth live.
