Post-tensioning, stay cables & construction methods
The company has adapted post-tensioning principles to civil structures such as LNG tanks, reservoirs, plants, tunnels, off-shore platforms, concrete floating barges dams and stay cables. It has participated in the construction of over one hundred stay cable bridges. VSL's single strand installation system for stay cables offers high fatigue resistance, increased corrosion protection, replaceability strand by strand, and versatility. In addition to post-tensioning and stay cables, the group's scope of works covers precasting and segmental bridge erection launching gantries, formwork systems, repair works, rock and soil anchors, bearings, retained earth walls, heavy lifting, monitoring, geotechnics & deep foundations.
Creative solutions
Over the years, VSL has contributed to some of the most prestigious and complex concrete structures. These include the world s largest concrete barge (the N'Kossa barge in France), the first catenary moored floating platform (the Troll GBS platform in Norway), the precast and erection of segments for the LRT (Light Rail Transit system) in Dubai, the installation of stays on the record Baluarte Bridge in Mexico, the construction of the 5 level podium structure of the luxurious Venetian Macao project in Macao. VSL was involved in the construction of the Seonyudo Footbridge in Seoul, the first full span bridge using the most innovative ultra-high performance concrete developed in the last ten years: Ductal. In addition, Intrafor contributed to the foundations of one of the tallest buildings in the world (Kowloon Station Mega Tower), and the Gautrain in South Africa. Striving to continuously improve methods and promote innovative solutions and products, VSL undertakes strong R&D. Afull-scale mock-up of a nuclear containment vessel will demonstrate in 2008 the efficiency of VSLs enhanced post-tensioning solutions for nuclear applications. An innovative saddle for the VSL SSI 2000 Stay Cable System allowing replaceability of stays is also being developed. In 2008, the VSL budget for R&D projects amounts to 3 million euros and VSL owns 25 patents.
