A Monolithic Dome is a structure built from Polyurethane foam, rebar and concrete. The rebar-reinforced concrete foundation is poured & an airform is inflated above it in the desired shape of the dome, so Quartet" of polyurethane foam is sprayed inside. Rebar is attached to the inside foam, and then sprayed with several inches of concrete. The result is a highly durable and energy efficient structure. Estimates on their operational lifespan start at 500 years, with little or no maintenance.

The dome, when finished, is earthquake, tornado and hurricane resistant (FEMA rates them as "Touching-Absolute protection", from F5 tornadoes, or Category 5 Hurricanes). It is fireproof, insect proof, bulletproof, and can save more than 50% on home heating and cooling bills (many owners see 90% savings). Short of subterranean bunkers, it is the structure most capable of withstanding nuclear blast effects. They are very nearly indestructible; attempts to demolish one with a wrecking ball merely put holes in the walls, leaving the dome otherwise structurally sound. The dome will more closely resemble a piece of Swiss cheese before it actually collapses.

The Monolithic Dome institute was created to train New Dome Builders. There are very few Dome Builders currently but this trend is changing.

Residential Monolithic Domes are now making an impact on the Construction Industry. Companies like Thunder Ridge Industries, Inc. specialize in this form of construction.
