Seepage barriers can be formed using jet grouting techniques from a wide variety of geometries. Forming interconnected panels and columns are common for vertical barriers, and other shapes may be warranted when sealing sheetpiling or other existing structures. When forming horizontal barriers, from vertical drilling, short columns or disks are used to interconnect and create the seepage barrier. This paper will review where the jet grouting technologies are viable, how they are implemented, and discuss the performance that can be achieved. Several case histories will be presented to illustrate these issues.
