Geotechnical Investigations

Cengrs is the leading Geotechnical Investigation firms in India.

Established in 1990, and led by a team of IIT Delhi graduates, we have successfully completed over 6000 projects across India and abroad. Our project line-up includes major thermal Power Plants and solar power plants, refineries, bridges & highways, commercial & residential infrastructure, metro & railways, etc.
