Soil Exploration – Purpose, Planning, Investigation and Tests

Soil Exploration – Purpose, Planning, Investigation and Tests

The nature and extent of soil exploration depends upon the ultimate use to which the results of the investigation will be applied. For example, for structures which transmit heavy load on the soil, the aim of soil exploration is to provide data which will help in the selection of proper types of foundation, its location and design of foundations.
