Soil is the main part of the foundation; it is very important to build a strong and durable structure. If soil is not stable then, there may cause the failure of the structure. In black cotton, the soil has a very low bearing capacity and high swelling and shrinkage characteristics it forms a very poor foundation, that cannot be affordable, India is the largest area occupied by black cotton soil. India is an agricultural country that comes in the top ten countries in the world it contributes many times through the agricultural field. India consists of 30-40% of Black cotton soil. Maharashtrian Western produces sugarcane on a large scale and bagasse formed by sugarcane. And to improve the strength of soil the stabilization (making more stable) of soil by conducting experiments on Black cotton soil by replacing bagasse ash (4%, 8%,12%,16%,20%). Another material mixed in black cotton soil is bio-enzyme (Terrazyme) with different dosages of 250ml/2m^3,250ml/1.5m^3,250ml/1m^3,250ml/0.5m^3 respectively. Due to this the strength of soil increases.
