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. Electrokinetic 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 current 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. The average current was observed for the 3 days using EKG on daily basis at
fixed time.
