Soil is the basic entity or to be more precise, it is a naturally occurring construction material which is primarily used for the foundation work. Naturally occurring soil (untreated soil) should have certain basic physical properties such as Bearing strength, Shear strength, etc. But with the advancement in the technology and modernization excessive construction has lead to the lack of good natural soil for the construction work. Poor quality soil needs to be treated with certain techniques of stabilization. But the fact being, these techniques are sometimes extremely expensive. This project serves the purpose as the alternative to these expensive stabilization techniques of soil. High Density Polyethylene(HDPE) is used as an additive in the soil to increase the physical parameters such as Bearing strength, Shear strength, etc. and to improvise the overall soil stabilization.
