There are numerous advantages that are acquired by utilizing a post-tensioned methodology. It takes into consideration adaptability of plan, quicker development and lower material expenses. Ludicrous term, it can decrease upkeep costs and take into consideration expanded burdens over the long haul. 

Extensions that use post strain ligaments can contain long and clear ranges, have not many bars and slim individuals and more slender sections can be utilized which is unimaginable in the event of normal scaffolds. This technique builds up or reinforces the solid or other material with high strength steel bar or strand which is known as "ligaments". It altogether decreases the structure weight and establishment load which is exceptionally valuable in seismic regions. 

Post pressure ligaments help in development of complex extensions which has explicit math prerequisites like complex bends and super height. Very long range scaffolds can be developed with the assistance of post pressure ligaments. Such models works viably without upsetting the traffic moving under it and furthermore diminishes the effect on climate fundamentally. 

Post pressure ligaments are made of prestressing strand, safe haven, pipes, and grout and erosion insurance materials. Since this innovation is new consequently there are no assessment frameworks for ligament parts. Late instances of erosion of post strain ligaments in complex extensions have become a huge issue. 

Subsequent to getting data about ligament consumption, division of transportation has investigated their post pressure structure stock to evaluate and measure the pace of ligament erosion and to assess the leftover life expectancy of the influenced part. 

Foundation Protection Company (IPC) has built up a complete post strain ligament investigation administration named "TendonScan®" which uses non dangerous testing and assessment techniques that can discover consumption and segment misfortune inside a PT ligament. 

What it is? 

As we have referenced over that it is a thorough ligament checking framework which chips away at non dangerous testing chiefs to discover voids, water interruption and draining grout in outer ligaments. This framework likewise incorporates a gadget to identify segment misfortune inside the ligament. 

For what reason was it created? 

During development of complex extensions, ligaments are filled in grout to forestall erosion. Be that as it may, during grouting measure, the grout will in general separate contingent upon grout's quality, admixtures, siphoning gear and techniques. This division result into low pH grout at ligament focuses and port which made these areas vulnerable to erosion.
