How It Works
Earthbuilt® uses a unique and rarely considered structural principle – traditionally compressive materials are particulates that are bound by firing, by cement or other chemicals or by glues. Earthbuilt® simply binds particles with an external tensile membrane. Genius.
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.
WHY EARTHBUILT IS SO STRONG
A short presentation of Our Earthbuilt Technology
Earthbuilt® builds better
“(Earthbuilt will be) similar to unreinforced load bearing masonry construction.“
Peter Standon, CEO,
Partridge Partners Engineers
With 23 years of research on prior art shows Earthbuilt® to be one of the most RESILIENT building materials, showing impressive structural performance even in BUSHFIRES, FLOODS and EARTHQUAKES.
Earthbuilt® mechanically turns waste into walls
- Earthbuilt® produces a continuous extrusion of waste (earth, old brick and plaster etc.) which is bound by a membrane, not heat or chemicals.
- Earthbuilt® is mechanically produced where it is needed, so it doesn’t need to be purchased, handled or transported. When laid, it’s hard and square, resembling normal courses of brick.
- Earthbuilt® doesn’t need high-quality clay. Layers can be tailored to the waste streams on or near the site.
