A recognized subsidiary

VSL designs and builds structures that employ post-tensioning systems, a technique for improving the load-bearing properties of concrete that extends the potential of concrete applications in structures such as long-span bridges and decks, etc. The subsidiary is also a major operator on other high added-value markets, such as cable-stay bridges, the reinforcement of existing structures, ground improvement techniques and heavy lifting of structures. Ever since 1956, VSL has contributed to some of the world’s most prestigious and most complex concrete structures. Some of the more recent of these are Tran Thi Ly Bridge in Vietnam, the Hodariyat Bridge in Abu Dhabi and the Baluarte Bridge in Mexico. Other projects handed over in the last few years include the Newmarket viaduct in Auckland, New Zealand, the elevated metro in Dubai and the Peace Bridge in Seoul, South Korea.

R&D as a driving force

With more than 30 active patents to its credit, VSL bases its development on a constant need for innovation and is investing heavily in R&D to maintain its technical leadership on post-tensioning and cable stay systems. Recent applications of its research programme have included improving the durability of saddle systems and stronger anchorage to comply with nuclear standards. Tested at the Technische Universität Berlin, the VSL SSI Saddle system successfully passed all the fatigue and tensile tests imposed by the most stringent international standards.
