Well-made monolithic domes, as described in the video, are expected to last for centuries. As described at the dometech.com website:
LifespanMonolithic domes are also relatively safe in a wildfire, due to the fireproof internal thin-shell construction. The external foam is apt to melt or burn unless protected by layers of fireproof material, but you should be safe inside the shell.
With the exterior protection of polyurethane insulation and the waterproof roof membrane, the steel reinforced concrete dome will not weather or decay. The life span of these buildings will be measured in centuries.
The monolithic concrete dome is probably the strongest building that can be built with a specific amount of time and materials. This means it has very high resistance to the natural forces of earthquakes, hurricanes, tornadoes, and floods. _dometech
The Formworks structural life-span is rated at 200-1000 years. That is five to ten times the structural life span of most homes. Plus - depending on what external features are chosen, the Formworks homeowner can reasonably expect a reduction of ninety-percent (90%) or more of the maintenance that is required on a conventional home of the same size. _formworksSome experiences of people living in Formworks homes
Here is yet another type of concrete home from Conrad'sCastles:
With poured-in-place concrete walls, there are no worries about rotting wood, termites, or settling problems that can cause a lot of interior damage. This means you have fewer headaches, more money, and more enjoyable weekends!
Strength and safety for your family.
Because of the concrete structure, these homes survive fires, tornadoes, hurricanes, and even earthquakes. What more could you want for your family? This also means cheaper homeowner’s insurance.
Peace and quiet.
You won’t believe how little outside noise you will hear in a concrete home! Noise from traffic or the neighbors’ barking dogs is practically gone. _Conradscastles
An arched or domed shape provides strength and uninterrupted interior space. Earth sheltering on top of the concrete provides further protection from fire and weather, as long as proper water-proofing is used. Monolithic domes, for example, are strong enough to be buried beneath about 30 feet of earth.
Homes that can last up to 1,000 years may seem like overkill. Of course if you plan to live in a house the rest of your life, you may wish it to be practically indestructible.
