Leka soils from LEHMAG are made from individual regional rammed earth and, depending on the customer's requirements and the demands of the application, with the addition of lime.
DEVELOPMENT: Loam is a mixture of clay, sand, silt (very fine sand) and, under certain circumstances, stones. It is mainly formed by weathering, erosion and sedimentation of rocks. Clay is therefore available almost everywhere in the world in different colours and compositions.
HISTORY: Along with wood and stones, clay is one of the oldest building materials of mankind. Even today, more than a third of the world's population lives in buildings that were built partly or entirely of clay, using various techniques. Even in Central Europe, centuries-old buildings are still made of clay, although the building material here was mostly used by poorer societies and almost completely displaced by concrete with the advent of cement.
