Sargacrete & Ashcrete
Recovered Resources. High-Performance Building Materials.
Composite materials engineered from processed sargassum and recovered fly ash — designed for structural applications where durability, sustainability, and performance converge.
The Challenge
Construction demands materials that balance performance, cost, and environmental impact
Supply Chain Exposure
Traditional materials depend on virgin extraction and long supply chains, creating cost volatility and geopolitical risk.
Environmental Cost
Construction accounts for 40% of global CO2 emissions. Sourcing from recovered feedstocks is imperative.
Waste Liability
Fly ash and industrial by-products accumulate as liabilities. Converting them to value addresses dual challenges.
Standardization Gap
Circular materials lack standardized testing and acceptance criteria by building codes.
The DURTEQ Solution
Engineered composites from bio-processed feedstocks
Biological Pre-Treatment
DURTEQ's biological processing improves material properties by selectively removing contaminants and optimizing particle distribution before composite formulation.
Engineered Composition
Formulated to meet target performance for load-bearing applications, with composition adjusted for end-use requirements.
Quality Assurance
Every batch tested and tracked through the AXERP registry, providing engineers with verified performance data and traceability.
Pilot-Scale Production
Currently in pilot production. Performance data from structural testing and field trials is being compiled to support building code adoption.
Potential Benefits
Circular Sourcing
Sourced from recovered feedstocks with verified supply chains and audit trails.
Performance Designed
Engineered for specific structural applications with testing targeting building code requirements.
Reliable Supply
DURTEQ's integrated acquisition and processing reduces cost volatility and supply fragmentation.
Cost Basis
Negative cost feedstock acquisition creates economic advantage relative to virgin extraction.
Target Applications
Foundation Systems
Structural fill, CLSM, and foundation base courses for residential and commercial development.
Pavement & Civil Works
Road base courses, sub-base layers, and embankment fill for infrastructure projects.
Industrial & Remediation
Site remediation, contaminated soil stabilization, and industrial construction applications.
