The picture depicts the procedures for constructing a storage area using a material called concrete canvas. Overall, there are several steps involved in creating the storage space, starting from manufacturing, delivering, pumping, unpacking, spreading, air pumping, watering, and resting.
To begin with, the first step is the production of concrete canvas, which involves three different materials. The top layer is made of fibrous material, combined with dry concrete, and finally covered with a waterproof coating. These components are packed and transported to the construction site, where the concrete canvas is unwrapped.
Next, the canvas is spread on the ground floor with the help of a machine attached to a rope. There are four pegs, one at each corner, measuring 10 meters in length. Moving to the next process, a large door is made vertically underground, and an air pump fills the space with air.
Moreover, the entire site is manually watered to a height of 8 meters. Finally, the materials rest for about one day to allow for proper bonding. After the setting process is complete, the storage site is ready, and items can be stored.
