VSL specialises in the development of prestressing systems for civil engineering structures and buildings, a technique which consists in improving the mechanical properties of concrete by adding steel cables incorporated in the structure. It also specialises in cable stay systems for large bridges. Through its network of 35 subsidiaries, VSL operates throughout the world.
VSL’s development is based on three strands:
- An active R&D policy. The firm concentrates its research on cable stays, of which it is one of the world’s leaders, and particularly on saddles. VSL’s prestressing process has obtained European Technical Approval, which recognizes its conformity with the highest current safety standards, thereby allowing it to be used throughout Europe.
- Establishing partnerships with related businesses. Together with Sika, VSL has developed CarboStress®, a prestressing system using carbon fibre that is stronger, more flexible and more economical. With Insituform Technologies, VSL has founded Insituform Asia Ltd, which specialises in the restoration of pipes in urban areas.
- Development of a sales policy based on alliances. These alliances allow access to new markets with a comprehensive solution that combines VSL’s know-how with that of its partners.
