One of the most common post tension services is using post-tensioning cables. Post-tensioning is done to reinforce concrete. Post-tension cables are steel tendons inserted in a plastic sheath and used in many structures, including residential buildings, water tanks, and bridges. They’re called post-tension because they’re used before concrete is placed. An anchor is placed by applying tension to the tendons which are cut at the anchor and sealed to prevent corrosion. But what are post-tension cables used for? Here are four common reasons to consider having post-tension cables.

1. To Add More Strength to the Building

According to Catalyst Condo, post-tension cables are primarily used to increase strength to thin or long slabs. Consequently, the span lengths between two columns can be longer. When an anchor is placed on the tendons, they apply tension. This tension compresses the concrete, thus enabling it to service bigger loads. Using post-tension cables increases the structure’s durability by minimizing cracking in the concrete. Post-tension cables reduce deflections and vibrations caused by hydraulic shrinkage.

2. To Save on the Amount of Cement Used

Another purpose of post-tension cables is to save costs by reducing the amount of cement used. Post-tensioned cables are used on thin and long slabs, thus minimizing the amount of cement and other building materials used. Furthermore, they allow for unconventional geometrical structures such as slender beams and more spaced columns. Post-tension cables reinforce concrete, thus reducing the need for more cement for reinforcement.

3. To Reduce Building Weight

A building can significantly benefit from having a lower weight because it reduces mechanical system and façade costs. Transporting materials might also be cheaper because of their lower weight. Post-tension cables help reduce material usage and consequently build weight. That allows for less load on the foundation and less need for more material usage on it.

4. To Increase Overall Efficiency

Post tension services are used because they increase the overall efficiency of construction. For example, they ensure more efficient use of building materials and allow for the construction of unconventional geometrical structures. They also allow faster construction through pre-fabricated segments.

Now you know why post-tension cables are used: to add strength, increase efficiency, and reduce the weight and amount of cement used. Do not hesitate to call us at Post Tensioning Solutions for the best post tension services, including post-tension cables.
