GEO 900

Flexibility

The GEO 900 was conceived as a mid-size hydraulic drilling rig for geotechnical works. This rig incorporates a particularly flexible design and accommodates many different accessories, which has allowed for an extremely diversified technical evolution of the GEO 900 over the years, including fields other than geotechnical engineering. Currently the GEO 900 is one of the most versatile models of the Comacchio line covering a large spectrum of activities related to geotechnical investigation, environmental studies and monitoring. These include soil investigations carried out with destructive and non-destructive coring techniques, Sonic technology, but also ground engineering works with the use of both rotary and/or rotary-percussive drilling. Due to the high mast pull force and rotary head torque output, the GEO 900 is also perfectly suitable for water well drilling and the installation of geothermal borehole heat exchangers carried out with single string drilling (both with mud circulation and a down-the-hole hammer).
