VSL Korea is one of the 35 worldwide subsidiaries of VSL International, which is a world-leading group in the field of engineering and construction based on post-tensioning and other state-of-the-art engineering technologies. VSL Korea has much reputable experience in the area of prestressed concrete structures such as over 200 concrete box girder bridges, over 20 cable bridges, over 20 containment structures (tanks for LNG, LPG, silo and nuclear power), buildings and heavy lifting structures, since its establishment in Korea in 1982. Recently, the company has constructed some of the most prestigious and complex concrete structures; Seonyu footbridge, Busan-Geoje fixed link project (immersed tunnel and 3 pylon cable stayed bridge), Handuri bridge and Mokpo bridge.
Post-tensioningVSL’s pioneering technology is based on the principle 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’s post-tensioning is proven to be more economical than other systems, especially when fast construction cycles are envisaged. This technology leads less material handling on site and labor force reducing which induce minimization of the site congestion. To make it better, the post-tensioning works by VSL Korea aim at “the best quality and service” through the technical tie-up with VSL International’s highly specialized team.
Global Network Over the past three decades after the company establishment, VSL Korea has grown into a nationwide engineering and construction company in collaboration with VSL International. It is proven that its clients have been greatly benefited from not only continuing development of special construction methods but information exchange taking place within the VSL network. Thanks to the technical support from VSL International as a licensor of VSL Korea for the full range of works from project planning and design to engineering, construction and other on-site activities, VSL Korea has been able to provide clients with innovative practical designs and construction solutions whenever it is demanded.
One-stop Service VSL Korea’s technological expertise has come to perfection through the accumulated construction works of up-to-date prestressed concrete structures. The construction experience by the company extends from bridges (concrete box girder bridges in ways of precast segmental method, balanced cantilever method, incremental launching method, movable scaffolding system and cable stayed / extradosed bridges) and containment structures (tanks for LNG, LPG, silo and nuclear power) to heavy lifting, damper installation, special structures (immersed tunnel and wind power plant) and post-tensioning in buildings.
As a general contractor, to provide “One-stop Service” with clients is the essence of VSL Korea.
