Strengthening of Structures using External Post-Tensioning System
In cases where a concrete structure in need of addressing concerns with strengthening due to deterioration, overloading, construction defects, or simply change of purpose, CTech-LLC®’sTensa-Ex™ External Post-Tensioning System is an ideal, engineered solution.Tensa-Ex™ External PT system provides active reinforcement by placing the concrete structure under compression in those regions where load causes tensile stress.
Tensa-Ex™ External PT system consists of high strength tendons (steel strands or bar) that are installed outside the structural element, protective ducting to improve tendons durability and/or fire resistance and the anchorages needed at both ends of structural element.
After the tendons installation, the tendons stretch as they are tensioned with a jack and locked into place using an anchoring component, introducing compressive stress on the structural member, which offsets the tensile stress the concrete member might face under loading.
CTech-LLC® Tensa-Ex™ External PT system has a well-earned reputation for its quality, reliability, and durabilityand issuitable for repair and strengthening works of buildings, bridges, tanks, , and special structures.
