“…Australian researchers studied factors of influence on hydraulic characteristics of geosynthetic clay lining [9]. As the scientists noted: "The results of this study will help minimize failures of liner systems in barrier applications, such as landfills, mines, tailings dams, significantly reducing the potential risk of groundwater pollution.…”

“…The application of geosynthetics in the geo-environmental industry is increasing rapidly due to its vast number of applications (Cheah et al, 2016(Cheah et al, , 2017Gallage et al, 2019;Garcia et al, 2007;Jayalath et al, 2018;Weerasinghe et al, 2019aWeerasinghe et al, , 2020. Geosynthetic clay liners are one such composite geosynthetic product with a core of low-permeability sodium bentonite clay sandwiched between two geotextiles or adhesive bonded to a geomembrane.…”

“…The most significant challenge faced by the industry is the failure of the liner systems due to separation of panels on side slopes, separation of panels due to shrinkage, punctures and wrinkles, installation faults, liner design faults etc (Fox et al, 1998;Rowe, 2014;Rowe et al, 2017;Thiel et al, 2005). Hence, significant research is being carried out to investigate how the overall hydraulic performance of the GCL could be improved by maintaining its optimum capacity throughout the barrier application (Daniel et al, 1997;Egloffstein et al, 2012;Mazzieri et al, 2015;Rowe et al, 1997Rowe et al, , 2016Weerasinghe et al, 2020;Xiong et al, 2009). The main factors identified affecting the hydraulic conductivity of the GCL are the overburden confining stress, shrinkage effect occurring due to the temperature variation, chemical compatibility of the bentonite to restrict various permeants, wrinkle effect due to the overlying geomembrane, and side slope shear effects (Fox et al, 1998;Thiel et al, 2005;Weerasinghe et al, 2019a).…”

“…Well-constructed and maintained geotechnical structures are crucial for the economy of any country. It is mainly because these structures are integral parts of many civil engineering projects related to embankments [1-9], road and railways [10][11][12][13][14][15][16][17][18][19][20][21], landfills [22,23], costal protection [24][25][26] and tunnel construction [30][31][32]. Therefore, the accurate measurement of soil or earth pressure is essential in laboratory and field investigation on the performance, and health monitoring of these geostructures [30][31][32][33][34][35][36][37][38].…”
