Engineering Geophysics caters to addressing varieties of subsurface investigations pertaining to civil and infrastructure projects. With the state-of-the-art facilities in Surface and borehole geophysical investigations, we use seismic, electrical and GPR survey techniques for defect mapping and stability evaluation. Because of its application in engineering judgment of site characteristics and post-failure investigations, engineering geophysical techniques are quite handy and indispensible.
In order to access the extent of old workings in Zinc mines, we successfully located them by cross-hole GPR survey. To assess the threat potential of subsidence around the buried oil pipeline of IOCL, we used cross-hole seismic survey to identify the potential threat zones. During foundation evaluation exercise post-grouting of the Chenab bridge pier, we mapped series of weak zones within the load bearing area leading to further reinforcement.
