After historic flooding to Fort Randall Dam, located in South Dakota, inspections made it clear there needed to be repairs toward the dam to promise long term stability. In order to reduce concrete shrinkage for such a large product, the owner chose to use PREVent-C admixture at a 5% dosage rate in their specialty concrete mix design. With 130,000 dowel anchors being required to be drilled into the concrete, PREVent-C would help the amount of strain it would create to the concrete.
