Quizplus · Accepted Answer

The minimum depth of the foundation for the black cotton soil is 1.5m. This is because black cotton soil is a highly expansive soil, which means that it swells when it comes into contact with water. This can cause the foundation of a building to crack and settle, which can lead to serious structural damage. By placing the foundation at a depth of 1.5m, the soil is less likely to come into contact with water and cause the foundation to swell.
