Post Tensioning Solutions investigated and repaired the existing button head post-tensioning system. This building lacked the concrete coverage needed to adequately cover the shims and stressing washers.
All anchors were sand blasted and cleaned of all rust and corrosion. Even though there was considerable corrosion, the system was still holding and did not need to be replaced. The anchors were galvanized, waterproofed and covered with an additional 3″ of concrete for future protection.
