2. Aircrete Building Questions
What is Aircrete?
Aircrete, is simply a mixture of water, cement powder, and a water-based foam. It’s also sometimes known as aerated concrete or cellular concrete. This unique building material combines the durability of concrete with the lightness of air. It’s made by mixing tiny air bubbles into a cement slurry, creating a lightweight, durable material that can be molded into almost any shape. > Read all about Aircrete here.
What do I need to start building with Aircrete?
The essentials are a foam generator, mixer, forms, and cement. Our bundles include the specialized tools — you’ll need to source cement, water, and an air compressor locally. > Read about the Domegaia Building System here.
What does a typical project cost?
Costs depend on design, location, finishes, and how hands-on you are. A simple guest dome can be built for ~$10,000–$20,000 in materials; multi-dome homes or boutique retreats scale from there. Aircrete delivers high value per dollar versus conventional methods.
What’s the cost per square foot?
Most small dome builds land around $200-$300 per square foot, including foundation, finishes, and labor. DIY builds can be as low as $50-$70 per square foot.
Do I need special permits to build?
Requirements vary by region. Because Aircrete isn’t in every building code yet, some areas ask for engineering approval. We can support your permitting path with structural guidance and plan adjustments; a local engineer typically provides the final stamp.
Can I build multiple stories with Aircrete?
Yes—with the right engineering. We focus mostly on single-story domes, but you can add lofts or second floors supported by interior walls, and multi-level builds are possible with proper structure.
How big can I build? Can domes be connected?
There’s no fixed limit—builders scale domes up, link multiple domes, and create compounds for living, hosting, and work. It's often more efficent and easier to build multiple connected domes than one giant dome.
Can I build this myself?
Definitely. Many first-time builders succeed with our tools + courses and a small crew. Our method was designed to be DIY-friendly.
Yes. Aircrete’s light weight and insulation make it ideal for remote/off-grid projects. Builders commonly integrate solar, rainwater catchment, and composting toilets.
Is Aircrete suitable for all climates?
Yes—Aircrete performs well in hot, cold, dry, and humid conditions. It resists mold, pests, and rot, and its thermal properties help stabilize indoor temps year-round.
Is Aircrete waterproof? What finish do I use?
Aircrete is porous, so finish it properly: stucco and elastomeric coatings are our go-tos for sealing and durability.
Can I add plumbing and electricity?
Yes—standard plumbing and wiring integrate cleanly into Aircrete walls and openings.
Is Aircrete only for domes?
No—while we specialize in domes and arches, Aircrete works for straight walls, sheds, furniture, benches, garden beds, and hybrid structures. Explore what is possible with Aircrete!
Plans are delivered digitally (PDF) so you can print, share with contractors, and submit for permits. Many plan packages include source files for customization.
Do I need a SketchUp membership?
No. You can open .skp files in the free version of SketchUp for Mac or PC.
Do I need plan approval or an engineer?
Often, yes. These plans are an excellent starting point, and our engineers provide the final approval to match local code. You can also contact us to help translate your Aircrete project into language your local authorities can understand—making the road to permits and engineering approval clearer, faster, and less stressful.
Can I customize the plans?
Absolutely. You can edit the provided source files yourself or ask us about plan customization services (e.g., layout tweaks, openings, climate-specific details, dome-to-dome connections).
4. Equipment & Bundles
What do I need to start making Aircrete?
Core setup: foam generator + foam-injection mixer + forms + foaming agent + cement. You’ll also need: air compressor (3–5+ SCFM @ 90 PSI), clean water, mixing barrels, and basic hand tools.
Includes: Dragon XL, Foam Injection Mixer, Metal Tubing Bender (3/4" EMT), Dome Builders Academy (6.5h), Aircrete Quick Start, Construction Manual, Architectural Plans.
How it all fits: Learn via Academy/Quick Start → generate foam (Dragon XL) → inject and mix (Foam-Injection Mixer) → bend EMT frames (Tubing Bender) → follow the manual/plans to build.
Includes everything in Ultimate + Full Access Workshop Pass (3 years) to attend any Domegaia workshop.
Why choose it: Combine online training with repeated hands-on practice, mentorship, and community at live events—perfect for those who want to master the craft or lead multiple builds.
Voltage: 120V standard (contact us for 220V options).
Why it’s better: Higher-integrity foam → fewer collapses, stronger bubbles, better compressive strength/R-value, and stable performance in cold/hard water.
Dilution:1:55 (e.g., 12 fl oz per 5 gal water).
Target foam density:~38 g/L.
Yield: Up to ~1340 gal foam per gallon of concentrate.
Throughput: About 2 gallons of Mearlcrete-S for a 16' dia x 4" wall dome (typical recipe).
Use with: Dragon XL and most foam generators.
Shipping: Free within the continental USA.
Shelf life:2+ years sealed, cool, and dry.
Dish soap? Works in a pinch, but is more sensitive to water quality. Mearlcrete is faster, more consistent, and easier to dial in.
Availability, shipping & support (equipment)
Most tools ship 3–5 business days after ordering. We stock replacement parts, provide setup guidance, and offer a 1-year limited warranty on mechanical tools (support continues beyond warranty).
What you get: 11 chapters / 56 lessons distilled from years of footage; live Q&A access; certificate of completion; upgrade credit (apply 100% of tuition to the Dome Builders Academy later).
Is it enough to build a dome? It covers core Aircrete techniques. For full dome/arch construction, we recommend the Dome Builders Academy.
Includes everything in Quick Start, plus: design reviews by experts, help on permitting hurdles, a quality design library, tools & materials checklists, and full build phases (foundation, stacking, reinforcement, finishing, electrical/plumbing, doors/windows, skylights).
Already bought Quick Start? Email aloha@domegaia.com for a special upgrade price to Academy.
Do I need to be very fit to do this?
People of many ages/abilities build with Aircrete. For on-site work, expect to lift ~50 lb with a partner at times.
What is the format and access of the online couses?
All courses are pre-recorded HD videos, learning is self-paced, and you will have a lifetime access.
Is there a guarantee?
Yes, we offer a 30-day money-back guarantee!
