The anchorage system plays a vital role in prestressed concrete structures by retaining the tensile force in the strands after stressing. This ensures the structural performance and durability of the building over its entire service life. That is why leading post-tensioning companies around the world — and in Vietnam — such as #VSL, #Freyssinet, and #PMEC have all developed their own proprietary anchorage systems. These systems are specifically engineered to meet both technical standards and real-world construction demands.

The development of proprietary anchorage systems by contractors aims to ensure that post-tensioning operations meet technical standards, while also minimizing force losses and reducing on-site execution errors. This leads to optimal structural performance and quality for post-tensioned elements and the project as a whole. The PMEC Post-Tensioning System has been researched and applied to suit all types of reinforced concrete structures in civil, industrial, and infrastructure projects. Building upon a research initiative by the Ministry of Transport of Vietnam on anchorage wedges in compliance with national standards (TCVN), PMEC has further developed its own anchorage wedge, synchronized with the anchorage head and bearing plate, all fully compliant with Vietnamese regulations.
