| Primary Mechanism | The tank is built using a skeletal armature of steel reinforcement bars and welded wire mesh, which is then plastered inside and out with a thin layer of cement-sand mortar (~2 cm). The mortar waterproofs the structure, while the steel mesh provides tensile strength to resist hydrostatic pressure, creating a monolithic, leak-proof container. |
