Clay is one of the oldest building materials in history. Clay bricks and clay mortar have been known for thousands of years. Loam is formed by the weathering of rock and is made up of clay, sand, gravel and silt. The grain goes from fine to coarse. Clay is considered to be the substance that determines the binding force.

With this correct clay mortar mixing ratio, it can then be prepared ready for use. In order to produce a good clay mortar, construction clay with a maximum grain size of < 2mm is used, which must be stone-free. Fine-grain and fine-fibre additives such as sand, chopped straw or plant fibers are used as additives. The clay content must not be too lean, but also not too rich. The result is a homogeneous mass that is processed directly.
