Technologies for durable structures
We ensure the development and constant improvement of our portfolio of patented technologies, including post-tensioning systems, stay-cables, ground anchors and VSoL® systems for retained-earth walls.

VSL
Every engineered structure must meet functional, architectural and environmental constraints while resisting heavy loads and harsh conditions. If not properly controlled, these forces can cause deformation, vibration or failure. That’s where VSL makes the difference.
As a specialist in structural technologies, civil works and ground engineering, VSL helps design, build, maintain and repair major structures, to guarantee performance, safety and durability. Our strength lies in a 360° approach that integrates engineering expertise, advanced technologies and efficient execution.

VSL is a global leader in structural preservation and repair across bridges, buildings, heritage structures, energy and mining infrastructure, marine structures, and water and wastewater infrastructure, helping extend asset life and performance.
We combine engineering expertise, proprietary technologies, strategic partnerships with expert niche companies, and decades of experience to diagnose deterioration, restore safety and enhance performance.
Operating in 20+ countries, VSL delivers tailored solutions that minimise disruption, optimise life-cycle costs and support long-term resilience.
