Land Based Geotechnical Investigation

Land-based Geotechnical Investigation is a field of Civil Engineering that deals with the technical behavior of earth related materials. A routine Geotechnical project ideally begins with a survey of underlying materials and their physical, mechanical and chemical properties. DBM comes in where such a site investigation is required and services projects pertaining to:

 Residential, Commercial, Industrial Buildings.
 Tunnels for Railways, Highways, Sewerage projects with maximum depth of 200m.
 Hydro-electric, Pumped Storage, Pipeline, Irrigation Projects.
 Cement, Power, Refinery, Roads, Highways & other major Plants

DBM boasts of a one of a kind Soil Mechanics Laboratory based in Mumbai where extensive testing is conducted on soil, rock and water samples. For a detailed list of tests visit our Soil Mechanics Laboratory section.
