Dome Construction Process

Many memorable structures throughout history, like the Pantheon, have been built using the thin shell hemispherical shape of the dome. These time-tested monuments surpass many in beauty and longevity. Continuing in the tradition of these magnificent edifices, Dome Technology engages the latest engineering and architectural technologies to produce aesthetic, functional, and economical schools, gymnasiums, waterparks, community centers, and industrial facilities. At a fraction of the cost of a conventional structure, each building benefits from unobstructed views, seating efficiency, great acoustics, and space utilization.

Modern insulated concrete dome construction combines several materials to create a strong, efficient, weather-proof structure. Compared to other types of structures for the same application. Insulated concrete dome construction consists of four main phases.

Ring Beam Footing

Continuous reinforcing bars are embedded in the ring beam foundation. These rebar dowels securely connect the dome to its footing. The ring beam creates a solid base on which to construct the dome.

Inflate airform®

Made of tough, weather-impermeable material, the airform® is attached to the ring beam footing. The airform® is then inflated with dual inflator fans. The airform® determines the final shape of the dome and becomes a protective cover when the dome is completed.

Polyurethane foam

The foam is spray applied from in the interior to stiffen the airform®, and provide a secure surface to which reinforcement bar is affixed. The foam hardens and creates a superior insulation layer in the final structure.

Shotcrete

A framework of rebar is attached to the interior surface of the foam. Application of sprayed concrete (shotcrete) to the reinforcement bar framework comprises the final step in construction of the dome.
