Presents the
SABSBuilding System
Foam-core, concrete-shell construction that builds faster, stronger, and more efficiently than wood framing — code-approved nationwide.
Who we are
Xtrata
An advanced building technology that replaces wood framing with a foam-core and concrete shell — designed to make construction safer, simpler, and more affordable.
- Formerly Strata International Group — developer of the patented Saebi Alternative Building System (SABS)
- Projects completed domestically and internationally across residential and commercial markets
- Growing licensed builder network with structured training and certification programs
- In-house design and engineering teams, permitting support, and ongoing technical field guidance
The system
One shell. Three jobs.
SABS replaces framing, insulation, and stucco with a single patented assembly: EPS foam panels wrapped in a SABScrete structural coating.
Set the foam
Lightweight EPS panels are cut, placed, and bonded into walls, floors, and roof — no lumber, no steel studs.
Apply SABScrete
A reinforced cementitious shell is sprayed and troweled over the foam, creating a monolithic structural envelope.
Finish directly
Paint, plaster, stucco, or cladding go straight onto the shell — structure, insulation, and finish in one application.

Six more reasons builders switch
Compliance
Approved nationwide & global
IRC
ICC-ES Evaluation Report ESR-1638 confirms compliance with the International Building Code (IBC) and International Residential Code (IRC), validating structural integrity, fire resistance, durability, and weather protection.
CRC
FBC
Supplements cover the California Building and Residential Codes, the City of Los Angeles, and the Florida Building Code — the two most demanding jurisdictions in the country for seismic and hurricane loads.
Engineered submittals are prepared for international authorities on request, with completed projects across four continents.

Operating cost
High energy performance
SABS helps builders deliver homes with dramatically lower operating costs.
- ENERGY STAR certified design — exceeds all current IECC energy code requirements
- Reduced HVAC loads allow smaller, less expensive mechanical systems
- Lower utility bills are a powerful sales and marketing advantage for builders
- Stable interior temperatures — comfort year-round
HERS (Home Energy Rating System) score and data points are from a completed SABS build in Arizona, 2026. HERS is a US rating where lower is better; 0 is net-zero.
Economics
Savings at a glance
SABS reduces shell construction cost and adds ancillary savings that lower total project cost.
Savings estimates are averaged across past SABS projects and are not a guarantee of individual project savings.

Beyond land
SABS floating houses
Man-made islands and floating structures from foam hulls wrapped in glass-fiber-reinforced concrete — U.S. Patent US8262321B1, inventor Nasser Saebi.
The creation of man-made islands and other floating structures using composite materials such as plastic foam coated with a fiber-reinforced coating (FRC), including glass-fiber-reinforced concrete (GFRC).
Continuation of Ser. No. 12/455,855 (2009), priority to 61/131,194 (2008). Incorporates U.S. Pat. Nos. 6,308,490 and 6,912,488 (curved structures in habitable buildings) and 6,721,684 and 6,985,832 (manufacturing and analyzing a composite building).
Islands built by moving sand are enormously expensive. Foam-and-FRC hulls are light, buoyant, and fabricated with the same crews and materials as a SABS home.
