CORROSION HAS A CLASSIFICATION.

YOUR SOLUTION SHOULD TOO.

From C1 to CX — One System. Total Protection.

The Hidden Reality of Concrete Deterioration

Corrosion isn’t random.
It’s predictable. Classifiable. Escalating.

The global standard ISO 12944-2 defines environments from:

• C1 (Very Low) → Controlled interiors

• C3 (Moderate) → Urban/industrial exposure

• C5 (Very High) → Coastal + high salinity

• CX (Extreme) → Offshore, marine, aggressive industrial zones

But here’s the problem:

Most “solutions” don’t adapt to the environment.
They sit on the surface—while corrosion advances beneath it.

THE SURTREAT APPROACH: ENGINEER THE SUBSTRATE

Not a coating. A system.

The Surtreat 3-Part UFGS Solution—aligned with
UFGS 09 97 23.17—is designed to work inside the concrete, not just on it.

1. Vapor-Phase Protection (TPS XII Technology)

• Migrates through concrete as a vapor

• Forms a protective molecular film on embedded steel

• Protects both anodic and cathodic corrosion sites

2. Ionic Penetration (TPS II Technology)

• Penetrates as a reactive silicate solution

• Densifies the matrix through ion-exchange chemistry

• Inhibits corrosion at the anodic level

• Reduces permeability and chloride mobility

3. Internal Seal (Repel WB Technology)

• Forms a cross-linked silicone barrier within the concrete

• Blocks water ingress without trapping vapor

• Preserves internal chemistry improvements

ONE SYSTEM. ALL ENVIRONMENTS.

From Low Risk to Extreme Exposure—Covered

• C1–C2: Prevent corrosion before it begins

• C3: Protect against urban pollutants + moisture cycles

• C4: Stop chloride-driven corrosion in coastal/industrial zones

• C5–CX: Deliver long-term protection in the harshest environments

Result: A unified system that adapts to exposure—not just appearance.

REAL-WORLD PROOF: OKINAWA

Extreme Environment. Measurable Results.

At U.S. military installations in Okinawa:

• ~80% reduction in corrosion rates

• Increased compressive strength

• Reduced permeability

Even after long-term exposure, treated structures demonstrated sustained durability gains.

WHY THIS MATTERS

Most asset owners are stuck in a cycle:

Inspect → Patch → Coat → Repeat

But corrosion doesn’t stop because you covered it.

It stops when you change the chemistry of the concrete itself.

THE BOTTOM LINE

• Corrosion is classified.

• Exposure is predictable.

• Failure is preventable.

And now—so is the solution.

SURTREAT® LIFE EXTENSION TECHNOLOGY

From C1 to CX — We don’t fight corrosion at the surface.

We eliminate it at the source.
