Evaluation, Repair and Protection of Unbonded Post-Tensioning in Parking Structures

Unbonded post-tensioning has been employed by engineers in the design and construction of buildings and parking structures for decades. Though the technology has evolved and improved over the years, early generations of the technology were highly susceptible to moisture infiltration and corrosion of the high tensile steel strands. This pernicious risk often flies under the radar until a strand violently erupts from the concrete. This webinar will discuss the methods of unbonded post-tensioning evaluation, corrosion mitigation and repair.
