Soil has important rank among the materials for the engineers because of its diversity of forms and their physical, chemical, mechanical properties and also because it is the part that moves the origin loads. Problems associated with soil properties calls for thorough study of soil, in order to avoid problems resulting from unknown soil characteristics. Major construction issues such as cracks in the concrete elements, and other flaws, all of which can be avoided through the prior study of soil characteristics on the construction site. It has been found that much more amount of investment is done to solve problems caused by soil after construction then actual construction cost. So by proper geotechnical investigation many problems caused during construction can be solved.
