Citadel Bridge Hamburg

The Lotse Canal separates Harburg’s Schlossinsel (“castle island”) from Hamburg city centre. To improve accessibility in both directions, the city authorities decided to build a new swing bridge for pedestrians and cyclists across the 44-metre-wide canal.
Task
Protect the structure and the budget. Hamburg wanted an innovative and cost-effective coating technology for the Lotse Canal swing bridge.
Challenge
Provide a proven coating solution. As a matter of principle, public authorities will only consider the introduction of innovative materials if their successful performance has already been proven beyond any doubt and they additionally deliver savings for the public handbag.
Solution
Polyaspartic technology protects the bridge and saves money. With years of experience of using this application in other fields of engineering, it was clear that Polyaspartic technology would protect the structure just as thoroughly against corrosion damage as previous coating systems – and, thanks to needing one layer less, would deliver savings at the same time. As a result, the swing bridge across the Lotse Canal became the first application of Polyaspartic technology in a public infrastructure project in Germany. The unique Polyaspartic technology benefits were confirmed by The Sherwin-Willliams Company, as provider of the coatings for the bridge: “Polyaspartic technology enabled a curing process that was four times faster than normal, resulting in a significant productivity boost.”

Why Polyaspartic technology was the right solution for this project:

• Ultra-durable: Thorough protection against corrosion.
• Economical: The need for one layer less cuts cost.
• Proven technology: Years of successful application in other fields.
• Fast-curing: Cures four times faster than conventional solutions.
• Ease of application: Good handling without the need for additional equipment or training measures.
