- The role of sand size and shape in behaviour of sand-bentonite liners [around highly contaminated wastes HCW disposed] has long been a disputable subject, attracting interest of many researchers. Based on our in-house developed principle of effective stress for unsaturated bi-modal soils, this paper presents a simple, expandable, and repeatable micromechanical model to show when, how and to what extent the shape, size and sorting of sand in clay liners impact the composite material’s state properties and serviceability of liners. The model is further simplified into a simple ‘decision-support’ colour chart, allowing geotechnical engineers to make informed, rapid, correct decisions
