Healthy Homes for American Samoa — Rainfall, Cyclones, and Freight
Virtual Home Health Score assessments on Tutuila and Manu'a. GaiaCrete™ evaluated against American Samoa's rainfall, cyclone code, and shipping constraints. Founding Mr Hemp House® dealer territories open by ZIP code.
Cyclone and tsunami dual hazard
American Samoa faces both tropical cyclones and tsunami risk, demonstrated in 2009, so siting and elevation matter as much as wall construction.
Extreme rainfall and constant damp
Rainfall in American Samoa is among the highest under the US flag, and closed imported-style houses trap that moisture where open fale design once released it.
Shipping-constrained materials
Every non-local material reaches American Samoa by ship, so weight, packaging, and schedule limit what can practically be built.
What Climate Zone 1A Means for American Samoa Homes
American Samoa lies south of the equator with rainfall measured in hundreds of inches a year in the Pago Pago highlands, plus tropical cyclone season and a documented tsunami history from the 2009 event. Traditional fale architecture solved that climate with open, ventilated, shaded structures, while imported closed-box construction often does not. Everything not grown locally arrives by ship, which makes material weight and packaging a design constraint.
American Samoa Building Code (with cyclone provisions)
The territorial code sets cyclone-resistant design requirements administered through the American Samoa Government.

Home Health Score
A free screening that scores your home across indoor air quality, moisture and mold risk, building materials, and ventilation — so you know where to look first.
Healthy Home Assessment
A professional walkthrough of materials, moisture conditions, and ventilation, delivered as a prioritized action plan. Screening and guidance — not a medical or diagnostic service.

- Thermal planning reference R-2.5+ per inch
- Class A surface burning characteristics (ASTM E84) — material behavior, not an hourly assembly rating
- Alkaline mineral composition may be less conducive to some biological growth conditions
- 100% Biobased Carbon Content (ASTM D6866-22)
- Vapor-permeable, hygroscopic, no added VOCs
- Net carbon sink by design
Actual thermal performance varies by formulation, density, moisture content, installation method, and complete wall assembly. Final whole-wall thermal performance depends on the complete assembly, including material density, framing, finishes, thermal bridging, moisture conditions, and installation.
