Post-Tension Repairs

Post-tensioned slabs are concrete systems in which high-strength cables are fully tensioned upon hardening of the concrete. Some of the benefits of this system include longer spans between columns, less overall rebar reinforcement and less shrinkage cracks. The main disadvantage of the post-tension system is the difficulty in repairing the system when a cable fails or snaps. First generation post-tension cable systems were not encapsulated, thus leaving the ends of the cable vulnerable to water infiltration and corrosion. This is a chronic problem in many coastline buildings, that if not promptly and properly addressed, can lead to significant repair costs and disruption in normal building operations. USSI has PTI-certified post-tension inspectors and has experience in assessing existing conditions, implementing site-specific maintenance plans for extended services life, and repairing post-tension systems that have failed.
