Unbonded Post-Tensioning

For unbonded post-tensioning construction, PTC Inc leads the way by providing the highest quality of products in the industry including the GTI Zero Void Anchor system coupled with quality domestic or commercial steel strands. 

Unbonded post tensioning is a way to reinforce concrete with high-strength steel strands known as tendons. An unbonded tendon is one in which the pre-stressing steel is bonded to the concrete at the anchorages. The most common unbonded systems are monostrand (single-strand) tendons, which are used in slabs and beams for buildings, parking structures, and slabs-on-ground.
