Monolithic dome

Monolithic dome is the creation of David B. South. This style of architecture is said to be nearly indestructible and has been proven to withstand Catagory 5 hurricanes, earthquakes, and even F5 tornadoes. They are impermeable to fire, insects, and rot. Other variations of the Monolithic dome include the geodesic dome, which are constructed of wood framing and are not usually as resistent to damages. Also, the geodesic is not weatherproofed.

Features

 * Monolithic Domes use half as much concrete and steel as traditional buildings.
 * The curved shape of the dome makes it resistant to wind and storm damage.
 * During earthquakes, Monolithic Domes move with the ground instead of collapsing.
 * Monolithic Domes cannot be damaged by fire, rot, or insects.
 * The thermal mass of the concrete walls makes Monolithic Domes energy-efficient.

History
David B. South created the first monolithic sytled dome in 1975 for potato storage in Idaho. Monolithic domes are created using balloon construction. The builder inflates a pvc airform (balloon). While the balloon is inflated, a grid of rebar is bent and formed in the shape of the airform to create the basic shape of the monolithic dome. While the balloon remains inflated, roughly 3 inches of concrete is applied over the rebar, once the concrete dries the balloon is deflated (for use again in most cases), and the basic monolithic dome structure has been created.

Newer styles of monolithic domes approach construction in a similar way. The airform is still used to create the ideal shape but it is now common practice to spray polyurethane foam before applying the concrete (in order to insulate the final product as well as to hold the rebar in place better). Newer versions of the monolithic dome may have a more finished appearance. The concrete finish is often replaced with stucco, wood shingles, or even stones. The monolithic dome has yet to hit a high in popularity because of its irregular appearance, the difficulty of building it (only trained contractors have mastered this building style), and the need for high quality air purifiers and humidifiers (thanks to the lack of seams). The largest monolithic dome recorded to date is 72 feet high and 280 feet in diameter, it is found in Birmingham, Alabama and is home of the Faith Chapel Christian Center.
