Geotechnical engineering laboratory is concerned with identifying the engineering behaviour of geomaterials (soils and rocks) and by-products such as fly ash etc. Geotechnical laboratory tests consist of number of tests for the properties of soil. These tests are done to find out the suitability of soil for the construction projects. This information is used by geotechnical engineer for designing the type of foundations, earthworks such as dams, embankments, tunnels, reservoirs, pavement sub grades etc.
