Geotechnical Engineering Division ever since its inception has been working actively in the traditional domain knowledge of soil mechanics and foundation engineering with focus on laboratory and field investigations. With the advent of knowledge, industrialization, space technology and fast computing techniques, frontier areas like landslide studies, earthquake engineering, application of remote sensing & GIS, geophysical investigation and environmental geotechnique got added with the traditional knowledge base. The division maintains liaison with industries and other user agencies to find application of its vast knowledge base.


The division has an excellent blend of human resources from the disciplines of geotechnical engineering, earth sciences, instrumentation and mathematics.

Some of the important infrastructures are:

  • Computer controlled Triaxial and consolidation Testing System
