Like all structural elements, cable systems deteriorate over time and require regular inspection and preventative maintenance. As critical load-bearing components, any defects identified in cable systems must be addressed promptly to ensure structural integrity. While modern systems incorporate advanced corrosion protection, older technologies and construction methods may lack such safeguards. Freyssinet offers efficient and proven solutions for the maintenance, rehabilitation, and upgrading of cable systems—ranging from internal post-tensioning tendons to externally exposed stay cables—ensuring long-term safety, reliability, and performance.

Our cable system solutions

Post-tensioned cables are designed to remain in service throughout the structure’s intended lifespan with minimal maintenance. Freyssinet offers specialist inspection services to assess the condition of your post-tensioning systems, helping to ensure their continued performance and structural integrity.

Stay cables are external to the structure and therefore more exposed to environmental conditions, making them susceptible to issues such as vibration and water ingress. However, when properly installed, inspected, and maintained, stay cables are designed to remain in service for their full design life with minimal intervention. Freyssinet provides expert inspection and maintenance services to help ensure the ongoing safety and performance of your stay cable systems.

Older stay cable and post-tensioning systems can be effectively enhanced through retrofitting with modern technologies, increased load capacities, and improved corrosion protection measures. Retrofitting offers a highly cost-effective solution for extending the service life and performance of existing structures—particularly in applications such as stay cable bridges—without the need for full replacement. Freyssinet specialises in the design and implementation of tailored retrofit systems to upgrade existing infrastructure to meet current standards and future demands.
