Overview of a Monolithic Dome

They are called Monolithic Domes and, as the name implies, they are circular, one-piece, steel-reinforced concrete structures that offer a number of advantages over more traditional bulk storage building designs. Here's a quick overview:

• Less costly to construct the silos
• More self-unloading than flat storage
• Simple foundation requirements
• Automated reclaim is easy to install and economical to operate
• Superior insulation qualities
• Condensation is virtually eliminated
• Maximum waterproofing
• Structures are adaptable for multiple use

Dome Technology improving its Domes

The hemisphere gives you the most volume for the least amount of surface area, explains Thomas W. Hedrick of Dome Technology. For many years, Dome Technology has constructed an average of 30 domes per year. Without knowing more, one would expect the company to just keep on building 30 domes per year, the same way it has in the past. However, the company's mechanical systems designers and engineers are constantly finding ways to improve the concept, resulting in better ways to build domes. In this article, we review how new design innovations are affecting the evolution of dome construction. Read More.

Benefits of domes for bulk storage

Domes are a popular storage option in the bulk storage industry. They vary in design from simple dome structures with low profiles, to domes with hemispherical shape, or dome silos. The dome is generally less costly than silos; additionally, automated retrieval is simpler and more cost effective compared to flat storage. Foundation requirements are generally simple and the dome can be erected swiftly, regardless of weather. The structure is strong, durable, insulated, offers maximum waterproofing and is not prone to condensation. The dome's ability to accommodate a variety of products makes it very popular. Read More.

Ecologica Carmelo Dome in Puerto Rico

The Ecologica Carmelo dome is the first dome of its kind built on the island for industrial purposes. A dome was selected over other types of storage systems because of its rapid construction, greater structural integrity and higher cost-efficiency compared to other construction techniques. The most efficient use of space was achieved with the concrete dome. With a diameter of 50.6m and 28.9m in height, the dome has a storage capacity of 34,000 cubic meters. In addition, a dome provides the most efficient structural system to withstand hurricane force winds. The construction of the dome from inflation stage to finished shell took only 42 working days.
