The provided diagram illustrates the eight-stage process of constructing a storage facility using a specialized material known as concrete canvas. Overall, the procedure transforms a flexible, multi-layered material into a rigid, dome-shaped structure through a sequence of preparation, inflation, and curing steps.
The process commences with the manufacturing of the concrete canvas, which consists of a fibrous top surface, a layer of dry concrete, and a waterproof base. Once manufactured, the material is delivered to the site and unwrapped. In the fourth stage, the material is spread across the ground, measuring 10 metres in length, and secured using pegs and ropes attached to a vehicle.
Subsequently, an air pump is utilised to inflate the structure, creating a dome shape. Once inflated, the exterior is sprayed with water to initiate the hardening process. The structure then undergoes a setting period of 20 to 24 hours. After this time, the concrete canvas hardens, resulting in a finished dome structure that stands 8 metres high. Finally, the interior space is ready to be utilised for storing goods, completing the construction cycle.
