The thin loam bread process is an earth building technique with which houses can be built in a way that saves capital and materials, but requires a considerable amount of personnel. This procedure is also called "Kraftsches procedure", named after the missionary Kraft, who demonstrated the procedure after an invitation from Gustav von Bodelschwingh in Dünne .

Emergence

In the period after the First World War there was neither capital nor material to rebuild the houses of the poorer population. However, clay was available in sufficient quantities and could be used as a building material. The technique is easy to learn and there were plenty of workers to lend a hand.

In 1923 Pastor Gustav von Bodelschwingh first built his own house in his home parish of Dünne ( Herford district ) with walls made of “loam bread”, a technique that he had got to know as a missionary in East Africa. By 1949, more than 300 settlement houses had been completed in this way, mainly in Bünde-Dünne and Ennigloh . Many of the houses are still inhabited today.

technology

The technology originally comes from Slovakia and Yemen . Their advantage over the rammed earth - and the cob technique is that these require much more effort and expertise.

In the clay bread technique, the roof is first erected and covered on round wooden supports, then the outer and inner walls made of clay bread are stacked underneath. The clay loaves (about the size of a brick) are formed on tables with your hands or with an extruder and laid in a damp wall bond without mortar. For better plaster adhesion, small holes are drilled with fingers or sticks and small stones are also inserted.

Two layers of lime plaster on the outer walls serve as weather protection. If the clay breads are made manually without an extruder, no technical assistance is required, which is an advantage especially in poorer regions.
