Geotechnical Rotary Rig (5 ft. Tooling)

Over the last 15 years Geoprobe® has increasingly been supporting customers focused on successful geotechnical investigations.  On many geotech sites, the need for speed and efficiency is of the utmost importance.  The specific methods of geotechnical sampling varies greatly and are usually dependent on a combination of subsurface site conditions and what is considered an acceptable practice in the geographic region.  The Geoprobe® Engineering Team set out to design a rig specifically for geotechnical sampling that could quickly perform SPT borings (augers and mud rotary), collect shelby tube samples, take rock cores, and push CPT cone…all on a 19,500 lb. GVWR truck that does not require a Class A or B CDL to operate.  From this vision, the all new Geoprobe® 3100GT was born.


Geotechnical Rotary Rig (10 ft. Tooling)

Specifically designed for customers focused on traditional geotechnical drilling applications utilizing: hollow stem auger, solid stem auger, SPT, mud rotary, air rotary, and high speed coring…Geoprobe® has released the all new Geoprobe® Model 150GT.

As we spent time with clients focused on rotary geotechnical projects, it became clear that some clients preferred 5 ft. tooling systems while others demanded speed; speed that could only be achieved by operating 10 ft. tooling.  There was really no single drillmast configuration that could offer our customers a real solution for every application.  For those customers that utilize 10 ft. tooling systems consistently, we are now able to offer a solution that we believe provides the drilling industry unique features that in the end will help Geoprobe® customers succeed.
