Rehabilitation of a pedestrian and cycle underpass using a pulled-in rehabilitation profile.
The Challenge
The project focused on making use of the existing structure and conserving resources, while avoiding disruption to traffic. A full replacement in concrete would have led to a road closure lasting several weeks. The rehabilitation method therefore needed to be fast, practical and carried out with minimal impact on traffic.
The Solution
ViaCon supplied a solution using the SWB 73 profile for the rehabilitation of the underpass. The rehabilitation profile was pulled into place using a chain excavator. Around 2,500 plastic caps were also used as part of the installation.
This approach enabled a fast, high-quality rehabilitation using corrugated steel. Compared with a new concrete replacement structure, the solution reduced cost and significantly limited traffic disruption. Installation was completed within 6 days, and the project was completed in March 2025.
