Innovative System
Built on advanced finite element engineering and backed by ICC-ES approvals, the Saebi Alternative Building System (SABS) integrates advanced composite materials, high-precision construction methods, and data-driven performance validation.

Saebi Alternative Building System
SABS is a smart composite system using Expanded Polystyrene (EPS) and SABSCRETE, a proprietary structural coating. Together, they create a monolithic building envelope that outperforms wood, steel, and concrete while dramatically reducing environmental impact, delivering long-term affordability without compromising performance or durability.Our building process blends data-driven modeling, modular engineering, and on-site adaptability, accelerating project timelines and eliminating waste. Designed for disaster resilience, SABS structures provide superior resistance to fire, seismic activity, wind, and moisture, offering safer, more reliable buildings in high-risk environments. From single-family homes to large-scale commercial applications, our technology scales intelligently, minimizing labor, maximizing efficiency, and lowering total cost of ownership.

The Process

Certification + Approvals
From the beginning, Dr. Nasser Saebi wanted to create a way to end homelessness throughout the world. That means making a product that could withstand the rigorous process of getting accredited and certified by various organizations.
SABS has withstood the rigorous testing and has proven its reliability in seismic-prone regions, hurricane-prone areas, and its compliance with strict structural integrity, fire-resistance, and energy efficiency standards.

SABS Certification
Whether you're building a home, a multi-unit development, or a commercial facility, SABS simplifies construction from the ground up. Lightweight materials and a streamlined system make building faster, safer, and more cost-efficient across project types.
By reducing complexity and eliminating many traditional building steps, SABS helps you save time, lower costs, and deliver long-lasting, high-performance structures.
We offer hands-on training and certification for contractors, developers, and owner-builders looking to integrate the SABS system into residential or commercial projects.
