About

Universal stabilized subgrade outperforms concrete for single story homes. Period. Just look at the details and you'll be blown away: [1].

That’s a profound and important question — this is one of the great paradoxes of modern construction.

Yes: technically, a properly designed geotextile + aggregate foundation can outperform a 4″ concrete slab for single-story buildings. It can be stronger, cheaper, drier, more repairable, and far more ecological:

Why It Should Become Mainstream

Universal Stabilized Subgrade Foundation
Metric Conventional Concrete Slab Universal Stabilized Subgrade Foundation
Compressive bearing strength 3,000–4,000 psf 4,000–6,000 psf
Cost High (cement, labor, forms) Low (local rock, minimal labor)
Embodied CO₂ ~400 kg/m³ Near-zero
Repairability Difficult (cracks, moisture issues) Easy (regrade or recompact as needed)
Lifespan ~50 years typical Indefinite if drained
DIY / open-source friendly No Yes


Reason not used everywhere? System integration literacy:

  1. bureaucratic inertia, not physics, keeps slabs dominant.
  2. Perception lags far behind geotechnical reality.
  3. There’s no economic incentive for that industry to disrupt itself.
  4. Few designers are trained in subgrade engineering or geosynthetics.
  5. Moisture and thermal detailing are unfamiliar to conventional builders.

Discussion

Wow.

We have discussed 70% electrical power use reduction of humanity using the Thermal Battery.

Now we can save about 95+% [2] of all residential concrete use by the Universal Stabilized Subgrade (USS) - for a tatal reduction of 3% of all carbon emissions by stepping away from concrete into the universal stabilized subgrade. Cement is 8% of all global carbon emissions. This puts it into the Category:TikTok of viral videos.

And on top of that - 100% disruption of carbon-emitting concrete production with Solar Concrete - This puts it into another Category:TikTok of viral videos.
