Practical example of bridge renovation – Sustainable solutions from CSZ

A bridge is more than just concrete and steel – it is a lifeline. The question is: do we extend its life responsibly or do we let it fall into disrepair and then rebuild it at a cost of millions?

➡️ From challenge to solution
CSZ recently oversaw the renovation of a heavily used bridge – from planning to implementation. The goal: to extend its service life, ensure traffic safety, and use tax funds efficiently. Right from the start of the project, it became clear that the damage was more serious than expected. Peripheral areas such as footpaths and cycle paths were particularly affected by de-icing salt, moisture penetration, and concrete degradation. However, instead of investing in expensive quick fixes or a new construction, we thoroughly analyzed the causes, flexibly adapted the planning, and closely monitored every measure – because every wrong step burns municipal money.

🛠️ Technical implementation – targeted rather than wasteful
Among other things, the following measures were implemented:

• Renewal of the road surface and sealing – to prevent chloride damage from occurring again.
• Professional concrete renovation with surface protection system – provides lasting protection against moisture and de-icing salts.
• Repair of the road transitions – technically challenging, but essential for durability.
• Sustainable protection of the bridge caps – less wear and tear, less maintenance, lower costs.

Conclusion: Every dollar was invested in a measure that demonstrably makes the structure fit for the future.

🌱 Sustainability = economic sense
Renovation is not a cost driver, but a cost saver.

• Preservation instead of new construction: Saves resources, CO₂, and millions of dollars.
• Innovative materials: Extend service life and reduce operating costs.
• Adaptive action: Prevents bad investments in the ongoing construction process.

When dealing with special assets in particular, this means that those who renovate responsibly create more infrastructure with the same resources.

🚀 Conclusion
This project clearly shows that doing nothing ultimately costs many times more.
Sustainable renovation means ensuring mobility, maintaining quality of life, and using tax money in a way that benefits future generations.
👉 Therefore: it is better to renovate properly now than to spend a fortune in 15 years’ time.
