Post-Tensioning Reinforcement

Post-tensioning reinforcement (P/T) is a method of producing prestressed concrete. The term prestressed concrete is used to describe the process of introducing internal forces/stress into a concrete structure during the construction process in order to counteract the external loads applied when the structure is put into use. Post-tensioning is done onsite by installing post-tensioning tendons/cables within the concrete form-work in a manner similar to installing rebar. Reduced cracking, reduced weight, and reduced maintenance all translate into savings, and are concrete solutions that have made P/T the premier way to reinforce concrete construction.
Some of the many advantages include: superior support for concrete slabs on the ground where soils are likely to move; reduces or eliminates shrinkage and cracking so no joints, or fewer joints, are needed; cracks that do form are held tightly together; allows slabs to be thinner and lighter which enables building slabs on expansive or soft soils or as multiple floors in a high rise parking garage.
A recently developed application of P/T is external post-tensioning for the strengthening or retrofitting of existing structures, especially as an upgrade to resist seismic forces.

Post-tensioned concrete is the preferred method for new tennis court construction and the rebuilding of old tennis courts. As the Post-Tensioning Reinforcement expert of Northwest Arkansas, Concrete Services, has constructed the tennis courts at Harbor High and Fayetteville High schools.

Post-tension concrete provides the best long term value for the following reasons:
• Ability to span unstable soils
• Increased resistance to settling and/or heaving
• Elimination of cold joints
• Better uniformity
• More controlled slope for drainage
• Stable, attractive concrete edge
• Lower maintenance costs
• Eliminates the potential liability from structural cracking
• Ability to construct over existing structures, thereby saving valuable resources associated with demolition and disposal

Post-tensioning reinforcement is an effective system that offers multiple benefits in terms of durability and economics. It also has proven to be a sustainable, low impact solution. Post-tensioning, when compared to conventionally reinforced structures, uses less steel and concrete while offering more usable space in a structure.
