Echo Dam is a 158-foot high earthfill structure on the Weber River in Summit County, Utah. Inspections concluded that modifications needed to be implemented with concerns of soil liquefying during a seismic event causing deformation of the aged spillway structure. Challenges arose before the project started such as the required low slump, long transport distance, and project timeline. The US Bureau of Reclamation chose PREVent C to reduce shrinkage cracks, based on successful field trials from the past. The use of PREVent-C can allow an increase in joint spacing, since the potential for concrete shrinkage cracks is greatly reduced.
