VSL IS COMMITTED TO
VSL's special construction systems have been used throughout the world since 1956. They are technically proven and have earned a well-deserved reputation for their quality and reliability. This has led to VSL becoming a recognized leader in the field of special construction systems/methods and related engineering
POST-TENSIONING AS CORE BUSINESS
VSL technology is based on the principal of post-tensioning where the prestress is permanently introduced into the structure after the concrete has hardened. This is achieved by the stressing of suitably arranged, high-strength prestressing tendons. VSL post-tensioning generates favorable stress conditions in the structure, enabling efficient use of the building materials while controlling deformations under service conditions. Complying with national and international standards, they are approved in every country where the use of posttensioning requires official certification.
VSL operates through 34 subsidiaries as a world-wide network, including two technical centres in Switzerland and Singapore, and two production facilities in Spain and China. With 2,900 employees, including 900 engineers and technicians, the Group provides technical consultancy and support for the full range of works from project planning to complete final design , construction engineering and on-site activities. STRONG COMMITMENT TO RESEARCH AND DEVELOPMENT
Recent R&D applications are enhanced systems for higher durability (saddle, anchorages) and for nuclear requirements (anchorages). R&D projects amounts to 3 million euro and VSL maintains 25 active patents
VSL ACADEMY – WORLD'S 1ST PT ACADEMY. A UNIQUE TRAINING FACILITY FOR POST TENSIONING TECHNIQUE
Competence is a key issue: based on the principle of continuous learning and training, and sharing of best practices through the network, VSL foremen, supervisors and site engineers benefit from centralized training in the VSL Academy where they are given best practice in all aspects of post-tensioning.
