Restoring the Strength of Post-Tension Concrete Systems

Post-tensioned slabs and beams are common in Hawai‘i's high-rise construction. However, corrosion or breakage in these systems can lead to serious structural concerns if not properly addressed. Corroded and ruptured PT cables generally become present during the concrete spall repair process. All ruptured PT cables must be repaired before closing the concrete.



Seal Masters of Hawai‘i provides specialized repair services for post-tension cable systems. Our technicians are trained to locate, evaluate, and repair damaged tendons using proven, industry-approved methods.
