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
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.
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.
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.
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.
