The following photos are of a repair needed on a water tank project. There were some issues with equipment which resulted in a cold joint/poor consolidation in areas. The contractor requested a site visit from a representative to evaluate the repair needed and to suggest a repair material. After visiting the site, US SPEC STR Mortar CI was suggested as the repair mortar. Many of these areas are deeper than 3” in depth, so the addition of pea gravel was suggested. This repair will be a form and pour application. (The white tubes visible in the photos will house the post-tension cables which, after tensioning, will be filled with US SPEC NA-100 Grout)
