Abstract A trial was conducted on a Victorian embankment to evaluate the use of electrokinetic geosynthetics for embankment stabilization. The embankment had been constructed by end tipping London Clay fill onto unprepared ground and has a history of instability. Ground investigations indicated a core of firm material underlain by softened embankment fill and alluvium and overlain by softened material towards the ground surface. The slope was treated to a maximum of depth of 7 m using electrokinetic geosynthetics and electrokinetic soil nails. Over a period of 42 days, electrokinetic treatment forced water out of the ground by raising it >4 m above the initial groundwater level such that discharge from activated electrokinetic prefabricated vertical drains (ePVDs) was >25 times that of control drains. Cation exchange processes were active as part of the treatment and correlated with reductions in plasticity and shrinkage. Overall DC power consumption was approximately 11.5 kWh m −3 of soil treated. Post treatment boreholes demonstrated that the soft material beneath the embankment had become firm and exhibited apparent improvements in both undrained and drained strength parameters. Pull-out tests on electrokinetic soil nails demonstrated an improvement in the bond strength of the nails by an average of 263%. Inclinometer data showed a significant reduction of movement tending to zero after treatment.
