The Geotechnics of Hydraulic Works Unit performs geotechnical-engineering studies for embankment infrastructures and provides specialised technical consultancy to multiple entities, particularly regarding design, construction and safety monitoring aspects.

Internationally, one may highlight the studies conducted in the Portuguese-speaking African countries and Brazil, in addition to the training and capacity building for their laboratories. In Portugal, NGOH contribution occurs within the scope of RSB (Dam Safety Regulation) as an advisor to APA (Portuguese Environment Agency) and as consultant for dam owners.
