SURTREAT IN AVIATION

Scientific Concrete Restoration for High-Demand Airfield Infrastructure

Aviation infrastructure lives at the intersection of extreme mechanical stress, aggressive chemical exposure, and zero-tolerance operational requirements. When concrete deteriorates—whether through cracking, surface fragmentation, jet fuel residues, or corrosion—the risk is not aesthetic:

It is operational. It is safety-critical. It is costly.

Across military installations, commercial manufacturing environments, and medical facilities, SURTREAT’s TPS II chemistry has consistently delivered quantifiable improvements in strength, permeability, pH recovery, and corrosion reduction—all without demolition.

This is a polished look at our proven impact across major aviation projects.

1. Boeing C-17 Assembly Ramps – Long Beach, CA

+62.6% Strength Increase & Reduced FOD (foreign object debris) Potential

Project Synopsis-Boeing Assembly Plant…

The C-17 assembly ramps were experiencing propagating cracks and FOD-prone surface fragmentation. Boeing required a solution that preserved operations while reinforcing the substrate.

TPS II Performance (ASTM C900 Pull-Out):

• Before: 4,842 psi

• After: 7,875 psi

• Increase: +3,033 psi (+62.6%)

Operational Value

• Higher resistance to wheel-induced shear and torque

• Reduced fragment formation under turning forces

• Improved durability of crack edges

Boeing summarized the outcome clearly:
TPS II demonstrably inhibited the formation of FOD-generating fragments.

2. Seymour Johnson Air Force Base – Runway & Taxiway System

99.5% Reduction in Water Permeability

Seymour Johnson Project Report …

Runway slabs from the 1958–1960 era had developed widespread cracking that was producing FOD and weakening the near-surface matrix.

SURTREAT’s TPS II was applied across an 1,800 sq ft evaluation area.

Measured Results:

Strength (Pull-Out):

• Before: 6,000 psi

• After: 6,850 psi

• Increase: +14%

Water Permeability (1 atm):

• Before: 10.0 cc/min

• After: 0.05 cc/min

• Reduction: 99.5%

Operational Value

• Vastly reduced moisture migration

• Slower crack growth

• Improved freeze–thaw durability

• Less surface raveling under aircraft loading

This project demonstrated TPS II’s ability to chemically stabilize older, high-strength runway concrete.

3. K-2 Aircraft Shelter – Republic of Korea

Strength +19% Avg • Permeability +1,200% Avg Improvement • Corrosion: Moderate → Low

K-2 Aircraft Shelter Report 200…

This joint U.S./ROK military evaluation remains one of the most comprehensive analyses ever conducted on TPS II (formerly GPHP).

Multiple locations were tested for:

• Compressive strength

• Water permeability

• pH

• Corrosion rate (Galvapulse)

Results Across All Test Areas:

Strength Gains:

• Range: +15% to +37%

• Average: +19%

Permeability Improvements:

• 614% to 1,678% reduction in water flow

• Average: 1,200% improvement

Corrosion Reduction:

• Average rates dropped from 50–60 μm/year (moderate)

• To 14–23 μm/year (low)

pH Restoration:

• Fuel-contaminated, acidic concrete restored to pH > 7

Operational Value

• Better steel passivation

• Longer service life inside shelters

• Reduced maintenance cycles

• Ability to treat contaminated surfaces without removal

Inspectors noted CAPO cones retained shape after treatment—a visible sign of improved cohesion.

4. Christiana Hospital – Helicopter Pad (Wilmington, DE)

Surface Durability & Chemical Resistance Restored

Christiana Hospital, Wilmington…

Helipads experience a unique mix of:

• Rotor wash erosion

• Freeze–thaw exposure

• Deicing and chemical contact

• High-impact tire loading

TPS II was used to strengthen the surface, reduce permeability, and mitigate corrosion.

Outcome Highlights

• Increased compressive strength

• Reduced chloride activity

• Lower permeability

• Improved pH profile

• Enhanced overall durability

This project confirmed TPS II’s ability to perform in thin-slab, high-wear aviation environments.

5. Patuxent River Naval Air Station – Four Pad Program

TPS II + TPS IV Delivered Significant Acid Resistance

Patuxent River Naval Air Station

New and older concrete pads near the taxi line were tested for durability improvements and chemical resistance.

After TPS II and TPS IV applications:

• Pads previously reacting violently to hydrochloric acid

• Showed minimal reaction after a 12-hour cure period

Operational Value

• Resistance to aviation fuel byproducts

• Protection from chemical spills

• Stabilization of both new and aged concrete

This result reinforced SURTREAT’s suitability for hangar aprons, fuel storage areas, maintenance slabs, and deicing zones.

6. The Aviation-Wide Conclusion: TPS II Changes the Substrate

Across all project data, five outcomes appear every time:

1. Measurable Increase in Strength

From +14% to +62.6% depending on existing condition.

2. Dramatic Improvements in Permeability

Including near-total permeability shutdown in some cases.

3. Restoration of Chemical Balance

TPS II elevates pH, stabilizes the cement matrix, and increases passivity.

4. Reduction in Corrosion Activity

Consistently shifting reinforcement from moderate to low corrosion rates.

5. Meaningful Reduction in FOD Risk

Especially in high-load, crack-sensitive areas (Boeing, USAF).
