A
Creative and Cost-Efficient Structural System
What is Post-Tensioning? Post-Tensioning
(PT) is a method of reinforcing and prestressing
concrete, masonry and other structural elements.
Concrete and masonry are very strong in compression,
but relatively weak in tension.
Bonded
Post-Tensioning
Comprised of multiple post-tensioning
strands housed in ducts, a bonded tendon is designed
to form a continuous bond along its length with
the surrounding concrete.
Unbonded
Post-Tensioning
Unbonded post-tension reinforcing, where the prestressing
steel tendon is not bonded to the concrete after
tensioning, provides a flexible reinforcing system
that meets architecturally complex projects.
