In ground improvement techniques like micropiles, soil nailing, jet grouting, and reinforced earth structures, the values of skin friction and shearing resistance between geomaterials and construction materials are considered in their design. However, it is very essential to estimate the stresses transferred along with the interface between geomaterials and reinforcement. Also, in the context of the study of debris flow after a landslide, the interaction between the debris and the surface material is crucial parameter to estimate the transportation parameters of debris material. When stress component is important for earlier studies, strain marks its importance in that of the later. Though the vast literature is available on the stress phenomenon, limited scope has been depicted on the strain parameter which is equally important. Hence, the present study aims to investigate the interfacial studies between soil and various textured surfaces and understand the interface behavior. The textures have been mimicked resorting to abrasive papers on a wooden block.
