Framing the Standard: NAVFAC UFGS 09 97 23.17
The U.S. Navy’s Facilities Engineering Command (NAVFAC), together with USACE, AFCEC, and NASA, established Unified Facilities Guide Specification (UFGS) 09 97 23.17 – Corrosion Inhibitor Coating of Concrete Surfaces. This specification defines minimum performance requirements for extending structure service life, reducing corrosion of reinforcing steel, lowering water penetration, and increasing pull-out strength of concrete.
SURTREAT Technologies’ TPS XII, TPS II, and Repel WB are explicitly identified in this UFGS standard, confirming their compliance with military-grade criteria and their suitability for high-value infrastructure applications. These products form a comprehensive, multi-phase system for penetrating, strengthening, and protecting reinforced concrete far beyond conventional surface coatings.
TPS XII – Vapor Phase Migratory Corrosion Inhibitor
• Gas-phase migration: Travels through cement pores to reach steel reinforcement without injection.
• Protective film formation: Creates a corrosion-inhibiting barrier on steel.
• Specification compliance: Listed in UFGS 09 97 23.17 as a vapor phase corrosion inhibitor.
• Best suited for: Bridges, parking decks, tunnels, and marine infrastructure.
TPS II – Ionic Migratory Corrosion Inhibitor & Strength Enhancer
• Liquid ionic migration: Moves in solution phase to protect reinforcing steel anodically.
• Structural recovery: Boosts pull-out strength by ≥ 500 psi (3.4 MPa).
• Specification compliance: Listed in UFGS 09 97 23.17 as an ionic corrosion inhibitor.
• Best suited for: Understrength mixes, rehabilitation projects, and durability upgrades.
Repel WB – Surface Sealant
• Cross-linked silicone matrix: Forms an insoluble, hydrophobic barrier within concrete.
• Moisture defense: Cuts water penetration by ≥ 80%, blocking freeze-thaw and chloride ingress.
• Specification compliance: Listed in UFGS 09 97 23.17 as the designated surface sealant.
• Best suited for: Enhancing and locking in TPS XII and TPS II treatments for long-term resilience.
Performance Benchmarks (UFGS 09 97 23.17 Minimums)
• ≥ 10 years service-life extension.
• ≥ 50% reduction in corrosion rate of reinforcing steel.
• ≥ 80% reduction in water penetration.
• ≥ 500 psi increase in pull-out strength.
The SURTREAT Advantage
• Specification-backed credibility: Listed in NAVFAC/USACE/NASA UFGS standards.
• Proven durability: Independently test-verified under demanding conditions.
• Economic value: Lower life-cycle costs by preventing premature failures.
• Sustainability: Preserves existing assets, avoids demolition waste, and reduces CO₂ footprint.
✅ Conclusion: Backed by NAVFAC and UFGS 09 97 23.17, SURTREAT’s TPS XII, TPS II, and Repel WB deliver measurable, specification-driven performance that strengthens, seals, and protects concrete infrastructure for the long term.
