Compressible soils, such as clayey soils, take time to consolidate as these type of soils have low permeability characteristic which slows down the flow of water out of the soil (Consolidation, in layman’s term, means the process of extracting water from the soil matrix in order to harden it for supporting or bearing loads from any structure). By electro-osmotic consolidation, it hastens the flow of water using electric currents between electrodes which are embedded in the soil that needs the development. It is much faster than the pre-loading consolidation technique however, the process will be an expensive one as it requires electrical power supply and electrodes spaced every 1 to 2 meter. Considering the time of consolidation using the pre-loading technique, electro-osmotic consolidation could be the solution otherwise other techniques such as PVD or vacuum could also be used.

There are Electrically Conductive PVD for this purpose. Such technic is being developed and recently applied successfully.
