The soil which is generally weak and possesses high deformation values in vast areas are covered with soil deposits having low shear strength and high compressibility. Clayey sands (SC) mostly tend to exhibit high liquid limit (LL) and plastic limit (PL). The technique of combining any two materials of different strengths to form a composite single material of greater strength is the frequent procedure followed in civil engineering practice. The soil is quite good in compression and weak in tension can’t bear the load alone. When a material of high tensile strength is introduced in the soil as a reinforcing material, the soil turns into a composite material and tends to possess relatively very high strength and attains the ability to carry loads of heavyweights. Reinforced earth is a technique primarily used to increase the ease of construction and cost-effectiveness. Keeping in view the research findings outlined about, in the present experimentation, it was carried out to investigate the efficacy of plastic gunny bags stabilizing the weak soil, thereby, improving the shear strength and bearing capacity of the soil. A systematic methodical process followed involving experimentations in the laboratory under controlled conditions. It was observed that 1cm thickness and 0.03mm thickness of plastic gunny bags with clayey sand effectively improved the shear strength and bearing capacity of the soil.
