Soil Exploration

A geotechnical investigation will include surface exploration and subsurface exploration of a site. Sometimes, geophysical methods are used to obtain data about sites. Subsurface exploration usually involves soil sampling and laboratory tests of the soil samples retrieved. Site investigation or Soil explorations are done for obtaining the information about subsurface conditions at the site of proposed construction. Soil exploration consists of determining the profile of the natural soil deposits at the site, taking the soil samples and determining the engineering properties of soil. It also includes in-situ testing of soil.  Soil is used as: Construction material as, for example, in the construction of dams, pavements, building etc., Supporting material (Foundation) for carrying the loads of the super-structure through their foundations.The field and laboratory investigations required to obtain the necessary data for the soils for proper design and successful construction of any structure at the site are collectively called soil exploration. The soil behaviour of the soil or the properties of the soil for design of the foundation are investigated. So, you should know what the property of a particular site where this foundation has to be constructed, so in that way you have to go for the field test as well as the laboratory test.
