Underwater Lagoon Repair – South Africa
Client: Freshwater Lagoon Owner
Scope: Underwater Refurbishment
Location: South Africa
Products: RA 500UW-LV
The large freshwater lagoon (c.40,000m2) in South Africa required to be refurbished with a coating solution that would provide long-term corrosion protection.
It was decided that the greatest time and cost efficiencies would be achieved by carrying out the coating application without removing the water from the lagoon.
As a result, the chosen coating solution had to be applied underwater whilst ensuring the required adhesion, corrosion protection and without contaminating the water in any way.
Chemco’s Diver-cote™ RA 500UW-LV was identified as the only viable coating solution on the market which could fulfill the application.
The underwater surface was prepared using a combination of water jetting and mechanical tooling which removed all prior coating/algae and created a suitable surface profile.
RA 500UW-LV was then applied to a thickness of 400μm using both brushing and power brushing.
The solvent-free, wet tolerant properties of the Chemco system allowed the coating application to be completed quickly and efficiently, with the lagoon returning to full service within the given timeframe.
• Wet tolerant
• Glassflake-reinforced for exceptional abrasion resistance
• Eco-friendly application with little dispersion in water
• Excellent adhesion to minimal surface preparation
• Excellent abrasion and erosion resistance
• Long-term, maintenance free performance
• No recoating limitations
Diver-cote™ RA 500UW-LV
Diver-cote™ RA 500UW-LV is a solvent-free, wet tolerant, low viscosity underwater coating which has been reinforced with glassflake and is recommended to be utilised for a wide range or underwater applications including the protection of risers, pipes and structures below the splash zone.
