Geotechnical works comprise the investigation of subsurface conditions and materials for the purpose of the determination of the relevant physical, mechanical, and chemical properties of these materials in supporting constructions of structures. The investigation is also done to ascertain presence of minerals that may be mined.

Geotechnical involves coring using drilling rig and analysis of the core to determine the rock types and their physical characteristics. Envo-Hydro solutions deploys appropriate drilling equipment and tools for coring and analysis of the cores.
