Provide instant stability, accelerate drainage and prevent liquefaction for an up to 12 m (40 ft) high road embankment.  The soil profile consists of soft to very soft silt and clay with some peat layers. Below an only 0.5 m dry crust, in some locations the soil is so soft that equipment as shown in the photo below would sink in without the presence of a geotextile reinforced work platform.

Electronic Cone Penetration Tests (CPTs), supported by digital process data from Vibro rigs, supplemented by full-scale load embankment trials and evidence from dug out columns.
