<p>Soils with poor engineering characteristics require effective and sustainable improvement to endure environmental and anthropogenic actions. For this purpose, physical, mechanical, and chemical techniques are typically employed to improve the engineering behaviour of such soils. However, these traditional techniques have a significant carbon footprint and are labour and time-consuming. This necessitates the need to devise novel methods to combat the challenges associated with soils having poor engineering properties. To this end, the electrodeposition technique has emerged as a sustainable alternative. In electrodeposition technique, a low-voltage direct current is employed on the target material in the presence of a chemical wetting fluid, which leads to the growth and nucleation of electrodeposits in the pores of the target soil with the assistance of a mineralization reaction. Electrodeposition improves the engineering and physical properties of the target soil. In a way, the electrodeposition is analogous to the natural precipitation of minerals which occur at the geological timescale, with the main difference being the application of the external potential gradient, which reduces the time of precipitation to hours and days. Consequently, electrodeposition underpins a valuable approach to modifying and improving the engineering properties of poor soils. Accordingly, this review paper presents the information and observations of the current scientific knowledge on electrodeposition in clay in a unified framework, as it will be crucial for advancing the mechanistic understanding of electrodeposition in granular media, specifically sand.</p> Graphical Abstract <p></p>
