Abstract :
    Electrokinetic injection is one of the most practical and economical methods and sometimes the only method for damp upgrading is used. In this type of injection of a substance that is injected as a slurry in the soil, sodium silicate, which penetrates into the pores and pores, improves soil resistance and reduces its permeability. In the forthcoming research with the combination of PSR, soil improvers and EC electrochemical methods, a method can be developed that can be of great help during gelling and penetration of the injectable material in soil pores. The question that has been studied and answered in this research. 1) What is the effect of electric gradient on EPSR efficiency? 2) 2) How does the concentration of sodium silicate solution improve soil quality with sand lens? In this experiment, the sandy sandy soil of Shiraz was used and the results obtained were prepared as follows: From the results of the study, it is deduced that the EPSR method led to the phenomenon of electro-kinetics and resulted in a sharp decrease in the permeability of sandy soils. This will be much higher at a concentration of 10%, due to the defect of the injectable injectables, their sedimentation and electrical conductivity, between the pores and the films and the bonding between the soil grains
