Adding Life to Concrete - A 20+ Year Success Story at Ports of Auckland

In 1999, Bledisloe Wharf in Auckland was facing potential replacement due to severe chloride contamination and corrosion. Our innovative Colloidal Nano Silica Hydrogel treatment changed that trajectory completely.

Key Achievements:

• ✅ Stopped ongoing corrosion - Independent inspection 10 years after treatment confirmed no further corrosion at previously tagged sites.
• ✅ Eliminated deck water leakage - Transformed from extensive leakage to a single small leak point, even during heavy rainfall.
• ✅ Extended service life by 20+ years - Structure remains in active use decades after treatment.
• ✅ Saved millions in replacement costs - Alternative cathodic protection system was abandoned due to cost
• ✅ Protected complete structure - Unlike cathodic protection, hydrogel technology protected pile caps, piles, and all deck surfaces
• ✅ Performed in challenging conditions - Overcame issues with bilge water contamination and tidal salt water exposure

The wharf remains operational today - a testament to the long-term effectiveness of penetrating hydrogel technology in marine environments. What began as a "hold strategy" to gain a few more years of service life became a long-term solution that continues to deliver value.
