We handle all the floor plan designs via telephone, fax and or email.

Because of the shape of the dome, a second floor is a natural. It is most cost effective to utilize the second floor for a guest room or storage.  However, any of our domes can be built without a second floor.

 

In a conventional house there is an attic which rarely gets used. To us it is just a space that holds hot or cold air which is waiting to leak into your house. In a dome the second floor space is useable versus being an unused attic space.

 

On the second floor of our domes even though you cannot stand all the way to the perimeter, there is ample useable square footage. To visualize the second floor useable space use the to-scale ruler in the back of the Stock Floor Plan Booklet (which is in the Planning Kit). Each mark is one foot. Cut out this ruler and use it to measure the second floor square footage that is six foot or higher from the dome shell. Note on the floor plans we have drawn in five foot, six foot and seven foot height lines around the second floor perimeter.


For example if you want to see how many feet on the second floor has six foot or higher ceilings, put the end of the ruler at the six foot height line on one side of the second floor and measure across the second floor to the other six foot height line and you will see how many useable feet is between the two six foot height lines.

 

If you choose a floor plan which maxs out the second floor and only leaves one fifth of the first floor open to the dome shell, you can have the following second floor useable square footages: 27′-225 sq.ft.; 30′ – 424 sq.ft.; 34′ – 614 sq.ft.; 40′ – 886 sq.ft.; 45′ – 1,127 sq.ft.; 48′ – 1,278 sq.ft. Generally most of our clients want only one half of the second floor installed. Therefore there are high vaulted ceilings over one half of the first floor, generally over the living room and dining room.

 

If you do not want to access the second floor by walking up the stairs, you could install a rail chair or a lift instead of an elevator. Your contractor would install an electric winch powered lift versus an elevator.


This way you can easily access the second floor rooms.

Q: What makes your panel concrete so crack resistant?

A: The panel concrete is a special formulation containing synthetic fibers and liquid admixtures. These ingredients improve the concrete’s characteristics, create super toughness, extend durability, make concrete impervious to water, give higher tensile and compressive strength, provide elasticity for expansion, and improve freeze protection. The concrete in your dome out performs other exteriors because of its specially developed formula. Because of its exceptional composition, it actually gains strength over the years. The exterior panel concrete adheres directly to the steel mesh and the E.P.S. insulation without the need of a bonding agent.

Q: I understand when I mix concrete on site to fill the panel seams; the recipe includes the same liquid admixtures and fibers that American Ingenuity used in the panel concrete. Is this true?

A: Yes, Ai ships the same liquid admixtures and synthetic fibers with the Building Kit so the seam concrete that is mixed on site in a mortar mixer not a cement mixer will have the same properties as the panel concrete that was applied at the Ai plant.  Fibers in concrete work to reduce the formation of shrinkage, (cracks in concrete’s plastic state) while helping to improve shatter resistance and reduce water migration. The result: tougher concrete.

The liquid admixtures shipped with your dome kit are marked A and B.  One is an air entrainment and the other is a water reducer.

The Concrete Mix recipe includes water, 1 bag Portland Cement (type 1 or 111), Admixture A, Admixture B, ¼ large bag fibers, Sand (called masonry or stucco sand….no rocks). The Assembly Manual includes the precise amounts for each of these items, and when to apply the admixtures.  During the assembly of the dome kit, the seam areas between the panels are filled with the special concrete in two applications.  In between the two applications of bonding agent, that is shipped with your kit, is applied on the first coat of concrete and onto the bonding ledge of each panel before the second coat of concrete is applied. Prior to the second layer of concrete being applied, decide the seam appearance, flat or curved.  The second layer is sponged so that its appearance is a “sponged sand finish” to match the sand finish, which is the finish on Ai’s prefabricated component panels. Prior to priming and painting the concrete allow the concrete to be rained on for one month to remove efflorescence. 

Prior to the application of concrete into the seams, all the prefabricated panel concrete or cured concrete around the area to receive the new concrete is watered down.  The “Old” concrete is kept wet while the new concrete is curing. Ai’s Assembly Manual explains step by step how to apply concrete in the seams and onto the entryway and dormer panels. 

Q: After all the seams between the component panels and building options are concreted, what is used to seal the concrete?

A:  Ai does not depend on the concrete to make the dome watertight. The dome is sealed with a concrete primer and two coats of good quality exterior concrete paint purchased locally.  Ai dome owners recommend the following paints:

  • Richards Paint: Rich Flex 245; use Rich Flex Alkali Resistant 100% Acrylic Masonry Coating for the primer.
  • Behr’s top of the line exterior latex paint is Marque. Seabrook Texas dome owner loves this paint. He uses semi-gloss. Marque has the most titanium in the Behr’s line.  – Home Depot
  • Sherwin Williams: Loxon XP Paint, Loxon Primer and Conditioner
  • Behr’s Premium Elastomeric Masonry, Stucco & Brick Paint –Home Depot
  • Seal Krete Paint (pigmented) –Home Depot
  • Ames Research Labs: Maximum – Stretch, at participating ACE & True Value Stores or can be purchased directly from Ames at 888-345-0809 (if using Ames paint, specific type sealants and primer need to be used.  TT3 sealant cannot be used.)

Q: I am considering applying elastomeric paint over the entire dome, should I do this?

A: Yes if the concrete was primed with concrete primer, if the paint is breathable and if interior water vapor is removed from the interior with Broan Bathroom Exhaust Fans, Top of dome exhaust fan, stove/microwave exhaust fans and use of Heat Recovery Ventilator or Energy Recovery Ventilator if needed in your area.  Water vapor accumulates in the dome from breathing, doing laundry and dishes, showering and should be removed from the dome. 

In northern climates, install a Heat Recovery Ventilator to remove moisture or check with your local HVAC subcontractor for latest solutions.  To read about Heat Recovery Ventilators click on HRV.

For an existing dome that has elastomeric paint applied to it, please do not remove the elastomeric paint.  Please call our office for the most current painting info for previously painted domes.  Phone 321-639-8777 Mon – Fri 9-5 eastern.

Q: What if I get a leak in the dome shell?

A:  Generally, it is easier to repair a leak in our concrete dome than it is to make a repair in a shingled roof. Applying EternaBond Tape (has MicroSealant) and textured knife grade patching compound is all it takes to seal the area if the concrete is bonded.  Call Ai’s office for more info (321-639-8777). 

Q: Where am I most likely to get a leak?

A: Where a passageway connects two domes, what Ai calls a link. A leak most likely will occur where the long flat roof of the link butts up to the curved surface of the dome shell. The expansion and the contraction associated with temperature changes produce the flex or separation at the link. The fall is the most likely problem time. Seal the area where the link meets the dome with the EternaBond Tape and textured knife grade patching compound and elastomeric paint.

Q: Explain why the use of a bonding agent helps prevent leaks.

A: Technology has developed now to prevent cold joints. The Assembly Manual that comes with the American Ingenuity Dome Kit explains how to utilize bonding agent and other techniques to join the concrete in the seams. Concrete, or a cement mixture, will not bond to a dry absorbent surface such as dry concrete. The reason is easy to understand when you examine the curing process of cement. When new concrete is applied over old, dry concrete, the moisture from the new concrete will be absorbed by the dry concrete especially at the surface where they meet. When the new concrete is robbed of its moisture at the joining surface it will not cure properly and therefore will not bond.

Bonding agents are designed to improve the adhesion between layers of concrete by acting as a glue and coating and sealing the dry concrete to prevent it from robbing the moisture.

Q: What else do I do during the seam concreting to assure that the second layer of concrete bonds to the concrete of the panels and to the first layer of the seam concrete?

A: This is discussed in detail in the Assembly Manual,  basically, wet the adjacent panels with water and allow them to soak up all the water they will before applying concrete into the seam areas. Plus apply bonding agent on the concrete ledge at the edge of the panel and on any concrete that has been placed in the seam before the second layer of concrete is applied.

Q: What other special features are designed into the panels of your kit to improve the bond and strength of your dome?

A: The pre-concreted panels have a ledge molded into the edge of the concrete where the seam concrete is most needed to bond. This ledge increases the bonding surface, thereby increasing the ultimate strength of the joint. The steel mesh, which extends from the old concrete to the new concrete is a small mesh which compliments the effect of the fibers in securing the joint.

Q: Can I spray concrete into the seams instead of hand applying it?

A: No. Ai does not recommend pumping or spraying the concrete into the dome seams because the equipment usually pumps faster than the seams can be finished. The over spray gets on the panels and unless it is washed off ASAP, it will harden and be difficult to remove.

Q: Why is it more beneficial to have pre-concreted panels instead of spraying concrete all over the dome on site?

A: A continuous sprayed concrete structure will cause the concrete to cure all at once.  Pre-concreted panels allow for the panel concrete to cure prior to the seam concrete being applied.

In 1976 American Ingenuity manufactured and then built its first geodesic dome prototype by utilizing reinforced concrete over E.P.S. insulation. Steel mesh was hand tied onto the propped up E.P.S. insulation, concrete was then gunited and troweled over the propped up E.P.S. insulation. Countless designs and manufacturing construction techniques were analyzed in the early years as American Ingenuity developed a new generation in dome housing. Ai has outgrown two previous models as we progressed to a five dome complex.

Ai does not recommend sprayed concrete structures because spraying concrete causes a waste of labor and concrete. The concrete ends up being 2″ thick in one place and 3″ to 4″ thick in other places. The concrete on the dome needs to be thick only in the seams and thin on the panels.  It is a waste of labor because it is difficult for the concrete finishers to stand in the concrete and try to finish the concrete as it cures.

Q: What is the curing time for the seam concrete?

A: The weather and the mix of the concrete (amount of water, etc.) will effect the curing time of the concrete. Usually by the time a complete row of panels is placed the next row can be assembled. If  a panel is placed above another panel and cracks start to form in the first coat of concrete, then the concrete has not cured long enough.  Stop placing panels until the concrete has cured and passes the “scratch test”.  Take a nail or screw driver and scratch the concrete if no indentation place the next row of panels.

The following article covers Geodesic Dome History.  Since ancient times scientists and astronomers endeavored to understand our starry night skies and create instruments to demonstrate their Charts of the Heavens.

In 1919, Dr. Walter Bauersfeld of the Carl Zeiss Optical Works in Jena, Germany completed construction of a hemispheric dome as a replica of the sky. He cut the vertices of highly subdivided icosahedrons in such a way that the new surfaces consisted of 12 pentagons and 20 hexagons arranged on great circles. Projectors were arranged in the center of the dome to produce 32 star fields on the dome shell.

When the complex skeleton of 3,480 struts, accurate in length to 2/1.000 of an inch was complete, Bauersfeld engaged the Dyckerhoff and Wydman Company, a leader in Ferro-cement to coat the dome sphere with several thin layers of cement to form a smooth surface which was then coated with white paint.

Basing the design on the ratio of the thickness of an egg shell to its diameter, Bauersfeld built the world’s first lightweight thin shell concrete dome.  He also produced the first dome comprised of geometric shapes which are now referred to as a geodesic dome.

Buckminster Fuller advanced the dome concept more than anyone and is known for giving the name “geodesic” to this type of polyhedral dome.

In 1976, Michael Busick, the founder of American Ingenuity, applied the polyhedral “geodesic” construction principal, in combination with the thin shell reinforced concrete technique and the use of expanded bead polystyrene (EPS) to advance the geodesic dome design even further.  For the first time a concrete dome could be built economically from a kit of component panels.  The design also exceeds all conventional housing in strength, energy efficiency and durability.

Mr. Busick’s design received a US patent in 1986. His design was a cover story in Popular Science magazine and has since received three NHBA Aurora Awards for energy efficiency, including the Aurora Grand Award and a Design Competition Award by Builder/Dealer Magazine,

Today, over eight hundred dome building kits have been shipped into 47 USA states and thirteen foreign areas.  Dome kits have been shipped from Florida to California ($6,400 shipping cost), to Tasmania by Australia (shipping cost $18,000) to Trinidad ($4,300 shipping cost). Why would a home owner pay these shipping costs?   Because they cannot build a home in their state or country that has the marvelous advantages of American Ingenuity domes…..extremely low energy costs for their home, super-strength 225 mph wind and F4 tornado warranty, noncombustible concrete exterior and experiencing the indescribable feeling of safety inside their dome.

In July of last year, the US Postal Service issued a commenorative postage stamp bearing a painting of Buckminster Fuller.  This painting originally appeared on the cover of Time Magazine January 1964 edition.

“Mr. Fuller reminds us all that America is a land of pioneers, haven for innovative thinking and the free expression of ideas.”  President Ronald Regan.
