Post-Tensioning - Buildings

Post-tensioning in building construction

Post-tensioning is a proven method to enhance the performance, durability, and cost-efficiency of concrete structures. In the context of buildings, VSL’s post-tensioning systems allow for thinner slabs, longer spans, reduced material use, and faster construction cycles. These benefits are especially valuable in high-rise towers, commercial buildings, parking structures, and industrial facilities. 

The Role of Post-Tensioning in Building Construction

Post-tensioning plays a key role in modern building design, enhancing structural performance while enabling greater flexibility and construction efficiency.

Post-tensioned tendons provide active reinforcement that increases load-bearing capacity and reduces cracking, allowing for more slender and economical structural elements. 

By reducing the need for intermediate columns, post-tensioning opens up floor plans and increases usable space. 

Prefabricated anchorages, reduced rebar quantities, and efficient stressing operations shorten construction cycles significantly.

FAQ about post-tensioning in building construction 

These are some of the most common questions we receive. Got another one? Reach out to us!

Bonded systems use grouted ducts to protect strands and allow force transfer along the length. Unbonded systems have individual greased and sheathed tendons, ideal for flat slabs. 

Yes. VSL systems are designed to meet seismic code requirements, and post-tensioning can help reduce damage by controlling deflection and cracking. 

Post-tensioning minimizes material quantities, reduces formwork, and enables faster floor cycles, resulting in labor and time savings.
