The Carillon Parking Deck Repair

Read all about this structural strengthening restoration on the Carillon Park Deck to see our Sika products in action!

A large, post-tension, concrete girder below the loading dock and dumpster container area had developed significant cracking which resulted in having to perform the epoxy injection, positive moment and shear strengthening. This girder had a flared concrete beams tying into one side which did not show any signs of stress-related cracking but would need to incorporate into the strengthening of the girder. As part of the original construction, one side of the girder had an electrical conduit chase poured monolithically with the girder, this portion was not positive moment strengthened. The girder intersected with perpendicular girders at one end in which the positive moment strengthening crossed over approximately 2’-6”. 

The solution developed by WGI was to add 6 rows of Sika Carbodur S1012 side by side along the bottom width of the transfer girder followed by placing SikaWrap Hex 103C 2x horseshoe wraps side by side along the entire length of the girder. At the flared beam tie-in, the SikaWrap was installed in an “X” pattern, followed by adding a horseshoe wrap at the transition point of the flare. The end of the girder to girder intersection also was wrapped with Sikawrap 103C 2x to aid in the end anchorage of the Sika Carbodur.

Stone Restorations crew had to first shore the girder and epoxy inject all of the cracks that were located throughout the concrete. After installing 700 epoxy injection ports and injecting almost 8 gallons of epoxy the beam was ready for strengthening. The strengthening began on day 1 with installing the positive moment Sika Carbodur S1012 followed the next day by the installation of the SikaWrap Hex 103C 2x.
