Webinar: Construction & Maintenance of Post-Tensioned Slab-on-Ground Foundations (DC10.2-17)-Construction & Maintenance of Post-Tensioned Slab-on-Ground Foundations (DC10.2-17)

Video Transcription

Video Summary

The Post-Tensioning Institute held its monthly webinar for April, moderated by Kyle Boyd, focusing on the construction and maintenance of post-tension slab-on-ground foundations. The discussion covered various topics and protocols important for ensuring the quality and durability of post-tensioning systems. The webinar emphasized the necessity of proper document control, delivery, and storage of materials to prevent damage, stressing safe handling procedures to avoid rust and ensure the integrity of tendons.<br /><br />The importance of site preparation was highlighted, underscoring the need for proper drainage and soil compaction to avoid foundation problems. Installation strategies were advised, including placing tendon anchors four inches from the edge of concrete and ensuring tendons are tied and chaired correctly to maintain appropriate profiles. The session delved into the construction aspects, discussing suitable concreting methods and finishing strategies to maximize structural integrity.<br /><br />The webinar introduced encapsulated systems, mainly used in corrosive environments, and outlined their potential applications. Stressing the importance of proper stressing techniques, the discussion touched on equipment calibration, elongation measurements, and safety during post-tensioning operations.<br /><br />Addressing job site troubleshooting, the webinar covered common issues such as tendon ruptures and equipment malfunctions, proposing solutions for improving longevity, like proper landscaping and drainage maintenance.<br /><br />Participants were advised to use detailed checklists and were encouraged to explore additional institute resources, such as training programs and publications, to deepen their understanding of post-tensioning practices. Future webinars will cover topics including barrier cable systems and innovations in post-tensioned bridges.
