Dome Storage


Developed to improve storage conditions, the building process of Dome technology is based on integrating waterproofing and insulation, guaranteed by a PVC membrane combined with the application of a polyurethane foam. The waterproofing of the dome is guaranteed by a PVC membrane that will create the initial forming and the exterior coating. Thermic insulation is guaranteed by the application of a layer of polyurethane foam on the entire inner surface of the dome.

Storage should not affect the original quality of the product being stored. Storage cannot improve the qualities of agricultural products, it can only maintain or deteriorate product quality. When the initial quality is good, it should also be good after a period of storage. Moisture is the worst enemy of many stored products.

The technology used for building storage is very important, as vapor drive exists. Concrete is not a vapor barrier and damaged seals in steel silo let the moisture or vapor pass. In such cases one can observe corn caking inside along the overlap of metal sheets, with colored kernels showing the penetration of moisture.

Domes are the ideal solution for the storage of bulk materials that are sensitive to temperature and humidity.
The dome structure guarantees the best level of preservation of the product stored even with extreme external conditions.
Domes are a completely sealed storage structure, allowing for better monitoring and dust emissions management.
The dome’s geometry allows a reduction of conveyor’s length and a simplification of the handling equipment. Domes can be filled through a simple opening on the top of the structure.
Reclaiming can be done by gravity or with mechanical/pneumatic systems. Reclaiming systems used within a dome allows a 98% reclaiming
The dome structure is considered the toughest structure with a lifetime up to 50 years. A dome can support very heavy top loads (700 tons). The structure is therefore very well accommodating for seismic and high wind areas.
Domes are cost efficient storage solutions, especially for high unit capacities. It requires mostly superficial foundations, avoiding piling and other expansive soil treatments.
Dome storage provides a large column-free structure capable of storing a high volume of product, up to 100,000 tons in one cell. The execution time for construction of a dome structure is very short compared to other storage solutions.
