Soil strata samples may undergo a variety of tests, starting with a classification test to determine the type of soil present at the construction site. In today's urbanization, especially in the construction sector, the importance of geology can only be understand after the events such as earthquakes, floods, landslides, collapses and destruction, which are caused by geological reasons and property destruction caused by them.
