In the current era, civil engineers are mainly indulged in the construction sector for improving
infrastructure of our country. This in turn alarms geotechnical engineer to go for building structure even in weaker soils
leading to the need of improvement of such soils. Electro kinetic process is one of the best methods of soil improvement
by dewatering, decontaminating and enhancing soil-chemical interactions. The present research work envisaged to study
various factors affecting dewatering using nonwoven conductive geotextiles with help of different nonwoven material and
steel mesh. The objective of paper is to evaluate the moisture content parameter and to study the effect of various factors
during the process of dewatering. The present study, for vertical dewatering four laboratory scale cylindrical models
were prepared for the experimental work. With the help of carbon rods acting as an anode and nonwoven conductive
geotextile which acts as a cathode current is applied to the soil for obtaining the required outcome. The different
parameters studied include effect of using different nonwoven geotextile and effect of preloading. The results were taken
for the moisture content for the preloading as well as using EKG on daily basis at fixed time.
