Soil nailing is a construction process utilized to enhance the strength of ground that ensures the safety of new or existing land slopes. The reinforcing action of the ground is increased via the nail insertion process which in returns increases tensile force in soil nail. The main part of the resistance becomes from the enlargement of axial force, which is a tension force. Specifically, cutting and bending may contribute little to the resistance. A number of bars are installed into a slope during the top-down excavation. The excavation support is an effective and economical way to build a retention wall to support hilltop, bridge abutments and highways. This process is effective on uneven soils, broken rock, shale and hard surface conditions. In this research, a physical model is prepared that comprises of pressure gauge, Acrylic sheet, flex sensor, multimeter and four steel bars. The soil for the model is collected from the campus of Chandigarh University. Sieve analysis is performed to determine the type of soil. To determine the effectiveness of the prepared mode a number of tests have been performed. Four different materials named as Hexagon Geonet, Tuflex Geonet, hexagonal drainage Geonet, and Biaxial Geogrid are used to determine the efficiency of these materials. From the experiment it is observed that Biaxial Geogrid can bear maximum stress of 78 Kg/cm2. Also the experiment is performed with flexible facing and rigid facing and concluded that rigid facing perform well with a maximum stress of 98 Kg/cm2.
