Earthbags are bags filled with soil or other natural materials, used in construction to create walls and structures. They are often made from durable materials like polypropylene or burlap, which can be filled with local earth, sand, or gravel. This method is eco-friendly and cost-effective, making it popular for sustainable building projects. The technique of using earthbags dates back to ancient times but has gained renewed interest in modern sustainable architecture. Structures built with earthbags can be strong, energy-efficient, and resistant to natural disasters. They are often used in earthship designs and other green building initiatives.
