The following photos are a repair needed on a water tank project. There were issues with equipment which resulted in a cold joint/pour consolidation in areas. The contractor requested a site visit from a representative to evaluate the repair needed and suggest a repair material. After visiting the site, US SPEC STR Mortar CI was suggested as the repair mortar to be submitted. Many of these areas were deeper than 3” in depth, so the addition of pea gravel was suggested. We recommend a rate 30% by weight per bag for extension of US SPEC products. This repair will be a form and pour application. (The white tubes visible in the photos will house the post-tension cables. After tensioning, they will be filled with US SPEC NA-100 Grout).
