01Executive Summary

Empowering Gabon's future through innovation.

The SABS Building System offers Gabon a unique opportunity to stimulate economic growth while addressing the nation's housing and infrastructure needs. Through local manufacturing, certification programs, and hands‑on training, SABS can create new jobs, develop skilled labor, and empower community members to participate directly in the construction industry.

By training General Contractors, tradespeople, and local residents to build with the SABS Building System, Gabon can establish a sustainable workforce capable of delivering high‑quality, resilient, and affordable housing throughout the country. Combined with local manufacturing operations and technology transfer, this initiative is designed to strengthen the economy, reduce construction costs, expand housing availability, and create long‑term opportunities for communities across Gabon.

02Building the Future Differently

Traditional construction can't keep pace with demand.

Rising material costs, labor shortages, and lengthy schedules constrain delivery. ELVIRA was conceived to answer these challenges through innovative community planning paired with advanced building technology.

  • Faster construction timelines
  • Reduced construction costs
  • Superior energy efficiency & thermal performance
  • Sustainable, community‑centered design
  • Scalable development & long‑term operational savings
03Why SABS Technology

An integrated structural & insulation system.

At the foundation of ELVIRA is the patented SABS Building System — structural EPS foam bonded with proprietary SABSCRETE™ coatings, delivering structure and insulation as one. Higher performance, lower cost, shorter schedule — certified under ICC‑ES Report ESR‑1638.
