Repair & Preservation Solutions

Extending the life, safety and performance of existing structures

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.

Our solutions

Structural Concrete Repair

Repair of damaged concrete through patch repair, crack injection, reprofiling, replacement, jacketing, hydrodemolition and protection systems.

Corrosion Protection

Solutions to slow, stop or prevent corrosion, including coatings, waterproofing, cathodic protection and chloride or moisture protection.

Prestressing Repair and Tendon Rehabilitation

Inspection, repair, re-injection, anchorage repair, external post-tensioning and tendon rehabilitation strategies.

Structural Strengthening

Load capacity, deflection control or change-of-use solutions using external PT, FRP, UHPFRC, Memory®-Steel or steel reinforcement.

VSL Memory®-Steel

Active strengthening technology using shape memory alloy reinforcement for existing concrete structures.

Bearing Replacement

Controlled lifting and replacement of bridge bearings and support systems.

Structural Health Monitoring

Monitoring systems to follow structural behaviour, durability performance and asset condition over time.

Heritage and Material-Compatible Repairs

Sensitive repair approaches for masonry, timber, early concrete, steel and mixed-material structures.

WHY REPAIR AND PRESERVATION MATTER

Restore performance and delay major reconstruction.

Address deterioration before it escalates.

Limit closures, downtime and disruption.

Restore capacity or adapt to new requirements.

Reduce demolition and unnecessary reconstruction.

Extend the value of existing materials and structures.

FAQ ABOUT REPAIR & PRESERVATION SOLUTIONS

These are some of the most common questions we receive. Got another one? Reach out to us!

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.
