Core Drilling Machine

GSI provides services for geotechnical investigation, exploring, prospecting, water well drilling and construction projects like road, bridge, water conservancy and hydropower, tunnel, industrial and civil construction as well as geological exploration, large diameter boring pile.

Portable pneumatic down-the-hole (DTH) drilling machine

For large diameter borehole drilling operations of rock excavation, especially advantageous for rugged and steep sloped terrain where other drilling rig can’t operate normally, GSI provides portable pneumatic down-the-hole (DTH) drilling machine available for the first time in Nepal. GSI is able to work in harsh environment, drilling in hard rock of small and medium-sized mine, earth and rock engineering and so on.
