Earth building also known as SuperAdobe is an affordable and sustainable way to build homes anywhere in the world. Polypropylene woven tubing or earthbags are filled with damp earth, tampered down and arranged in layers to form a dome. Strands of barbed wire secure each layer while acting as reinforcement. Permanent structures should be rendered over with a mixture of earth and cement to protect the polypropylene from the elements and strengthen the structure. Earth building is a fast and flexible construction method which the whole family can enjoy. Earth building material is used to build Eco Dome houses, retaining walls and for flood & erosion control. When built correctly Eco Domes are earthquake, fire and flood-resistant structures which can be made to suit a single person or a large family.
