We have established our reputation as a company committed to providing engineering solutions to complex geotechnical problems as well as developing economic and safe designs for foundations and soil-related problems. Our project line-up includes major thermal power plants, refineries, bridges & highways, commercial & residential infrastructure, metro & railways, etc.
We are represented in several national forums such as Indian Geotechnical Society, Deep Foundation Institute, Association of Consulting Civil Engineers, Indian Roads Congress and Indian Society of Rock Mechanics & Tunneling Technology. Our directors have served these forums in various capacities. Our directors are also members of the technical committees of the International Society for Soil Mechanics and Geotechnical EngineeringBureau of Indian Standards and Indian Roads Congress and have been instrumented in drafting various codes and policies related to geotechnical engineering, piling, fly ash utilization, etc.

For us at Cengrs, “QUALITY” is a habit, to actively pursue on a routine basis, not something that is unwillingly imposed upon its staff by the company management. We recognize our commitment to the society at large and are aware of the implications of our work in nation building. We work with the motto “We test today for tomorrow’s progress”.
