To have the information’s about the physical properties of soil and rock, to design foundations for different structures and the Geo-tech investigations are performed.
Also Geo-tech Investigations are used in measuring the thermal resistivity of soils, oil and gas pipelines etc. Geotechnical investigation includes surface exploration and subsurface exploration of a site. Subsurface exploration usually involves soil sampling, laboratory tests of the soil samples etc.
In any geotechnical investigation, the general tasks are as follows:
Determination of soil profile and groundwater status within the proposed site.
Recommendations for foundation design and construction of various building structures and underground utilities.
Recommendations for site preparation and surface drainage
Recommendations for constructing parking areas and driveways (for light and heavy-duty asphalt paving).
