Formed Earth (Straw Clay)

Very clayey soil, in a liquid state, is poured on straw, which has been chopped to the desired length. The mix is generally tampered afterwards into forms. These walls are not load-bearing: they are light, have a very high thermal insulation value and must be built in a wooden structure. It was traditionally used in Germany and was re-used for reconstruction after the 2nd world war. It is mostly known with the name Straw clay. Straw clay can be used as a filler wall, formed between a wooden structure or as prefabricated blocks.
