Keller Group constructed a 13 m deep underground parking lot. After many trials utilizing concrete diaphragm panels for ground support, this approach was found to be impractical. This was mainly due to the high aggregate-size variability of the morainic deposit (unconsolidated glacial debris) at the site. In such complex geotechnical situations jet grouting offers a valid alternative to traditional support systems.
