Sustainable bridge renovation – a CSZ practical example

Responsibility in action
Climate change is one of the most pressing challenges of our time. CSZ takes this responsibility seriously and focuses on innovative, sustainable solutions. In this article, we present an outstanding example of our work: the comprehensive renovation of a bridge, which we managed from planning to implementation.

Project overview: from vision to reality
The bridge has been closed for a thorough renovation since mid-March 2024. Our planning objective is to significantly extend its service life. The road surface and waterproofing will be renewed with the aim of restoring the road safety and durability of the components. The primary damaging effect of de-icing salts is essentially caused by a defective seal. Accordingly, the level of care required for this renovation work is particularly high and so are our monitoring activities as part of service phase 8 of the HOAI. The same procedure is planned for the wearing parts of the bridge deck.

Once the areas damaged due to years of chloride ingress into the concrete have been repaired, a surface protection system is applied to the bridge caps to keep de-icing salts away from the concrete structure. The roadway transition structure will be professionally repaired.

The importance of sustainable bridge renovation: future-proof solutions
Sustainable bridge renovation is essential to counteract the ageing and loss of function of infrastructure structures. By reusing existing structures, we conserve resources and reduce the ecological footprint. Innovative measures improve energy efficiency, reduce operating costs and extend the service life of the bridge. The use of recycled materials and modern technologies ensures that the investment is future-proof.

This project illustrates CSZ’s commitment to sustainable infrastructure and responsible urban development. Through precise renovation measures and innovative approaches, we make an important contribution to the preservation and improvement of existing structures – for the present and future generations.
