Post-tensioning is VSL’s core business. Multistrand and monostrand systems are used in every area of concrete construction. The post-tensioning principle is also applicable to stay cables and external tendons. VSL’s understanding of prestressing has also led to the development of the VSL heavy lifting technique which provides safe and cost-efficient solutions for lifting and lowering of large and heavy loads. In addition, VSL offers form travelers for construction of balanced cantilever concrete bridges.

VSL provides technical support during the planning and construction phases of projects. Our comprehensive range of services includes feasibility studies, preliminary designs, alternative proposals, detailing, project coordination, and contractor consulting. VSL can also execute the work utilizing VSL personnel and equipment.
