Repair & Preservation Solutions
VSL helps asset owners extend the life, safety and performance of existing structures through integrated repair, strengthening, preservation and monitoring capabilities.
Every structure ages. Exposure, corrosion, cracking, fatigue, fire, impact, changing use or evolving regulations can affect safety, durability and performance over time.
VSL supports asset owners from assessment to repair, strengthening, monitoring and lifecycle extension, combining structural engineering, specialist technologies and field execution to restore performance, reduce lifecycle costs and preserve existing assets.

FAQ ABOUT REPAIR & PRESERVATION SOLUTIONS
A structure should be assessed when visible damage appears, after impact, fire or extreme events, or when use, loads or performance requirements change.
Repair restores damaged elements or materials. Strengthening increases structural capacity, stiffness or performance.
In many cases, yes. VSL can develop methods designed to limit downtime, closures or disruption.
Yes. VSL can support tendon inspection, anchorage repair, grout re-injection, protection replacement, external post-tensioning and tendon rehabilitation.
Yes, VSL can support bridge bearing replacement as part of repair, maintenance or strengthening works. This type of operation may involve inspection, temporary jacking, removal of existing bearings, installation of new bearings and verification of structural behaviour. Bearing replacement is usually planned carefully to minimize traffic disruption and ensure safety during works.
Yes. Extending the life of existing structures can reduce demolition, reconstruction and material consumption.
Yes. VSL also supports steel, masonry, timber and mixed-material structures, depending on the project and local expertise.
Memory®-Steel can be used to strengthen various existing structures, depending on technical feasibility and project conditions. Typical applications may include concrete or masonry elements in bridges, buildings, slabs, beams, walls or heritage structures. It is especially relevant where targeted strengthening, limited intervention and improved serviceability are required.
