While electric field is being applied, permeability of soil is increased by factor of two or more, thereby reducing time required to introduce group when pumping at specified pressure; electric field also acts to pump grout into soil or causes development of negative pore pressures near grout pipe which effectively increase grouting pressures without increasing danger of surface heave; summary is presented of some recently reported, successful applications of electrokinetics in grouting in Roumania, Israel, United States and Great Britain; several possible limitations of method are suggested and indication of cost of power is presented.
