Drilling depth capacity’s are based on feedback from field operatives and can be reasonably expected with vertical, water filled holes, by well-trained drilling crew

using high quality drilling tools. Gemsa cannot guarantee that these results will be achieved in all drilling conditions.

(-%20) safety margins are considered on components capacity’s.

GEMROCK GDT is small and efficient machine, designed for high

performance and productivity with ease of maintenance in mind. Proven

itself from easy access open drill sites to the remotest steeply soft

formations. Suitable for energy hole, water well and geo-construction

applications and can achieve depths approaching 280 meters in good

conditions. The machine offers a comfortable operating environment

with adding smooth interaction of the modern control systems with

simple icon displays, carefully designed ergonomic features and

excellent visibility. Thanks for the in line design, all components very

accessible for fast and safe servicing.

GEMROCK GDT is known as high performance in terms of speed,

reliability and long life. Suitable to adapt narrow environments .
