Earthbags

The earthbag building way is both new and old. Sandbags have been used by the army for fortification works or for controlling  the streams of rivers. The same reasons that have established earthbags appropriate for the tasks mentioned, also apply for building houses. Really solid and stong walls are being created that can withstand all kinds of loads, from bad weather conditions to bullets and bombs.

Earthbags can be built really fast and with very few and basic tools.

This technique was introduced as a house building method by the architect Nader Khalili, who was experimenting using earthbags as structural elements, creating domes and arcs. Khalili was familiar with building techniques from the Middle- East where adobe bricks are used to create structural elements of this kind. His observation was that bags filled with earth are ideal for dome shaped houses. The bags are filled with slightly moistured loamy earth and are stacked one on top of the other in layers which are compressed really good to take the air out. At the beginning, hemp bags where used which functioned perfeclty until the bags rot. They were succeeded by polyprpopylene bags which, if kept out of solar light, have greater resistance. At permanent constructions the bags must be covered by plaster. And while Khalili died the earth bag technique continued evoluting.

Their most advanced form is called hyper adobe, where lattice bags, that come in 1 km rolls, are used. As a result, we have more solid constructions without the need to of in- between bonding elements, easier to build, with enhanced breathing abilities.
