Summary
[edit]DescriptionJet grouting- a surgical approach to levee work (11357087973).jpg | Crews operate a jet grout drill at a levee section along the American River in Sacramento, Calif., Dec. 11, 2013. This U.S. Army Corps of Engineers Sacramento District levee project at the E. A. Fairbairn Water Treatment Plant is using a precise construction method called jet grouting to inject a seepage cutoff wall around the plant’s buried utilities. The Corps installed more than 20 miles of seepage cutoff walls into American River levees between 2000 and 2002, but work was set aside for later where complicated encroachments existed such as utilities, power lines and bridges.
