Earthbuilt® is extruded from a machine that runs along the ground or uses a wall or foundation as a track. As it goes it builds up layers, very much like courses of bricks.

Loose fill goes into the hopper at the top – and it’s wrapped as it’s being extruded. The fill can be various types of earth, like sand, clay and gravel. Or you can up-cycle waste like crushed brick, glass or concrete.

It’s when it’s wrapped that the magic happens. This binds the highly compressed fill in place, so it can’t spill or crush, in a structural system called ‘terre armée’ or in English, reinforced earth.
