Geotechnical Drilling Rigs by Geoprobe®

Effective Versatility to Advance in the Industry

Complete your geotechnical investigation faster, easier, and safer when using a Geoprobe® geotechnical drilling rig. The low impact and maneuverability of the geotechnical drilling rigs allow for free movement on geotechnical investigation sites with limited access, such as next to foundations, inside buildings, or under power lines. But don’t be fooled by the small footprint. These rigs pack the pull and push power necessary to complete your geotechnical investigations for roadways, buildings, tunnels, and levees while also providing the control to fine tune your geotechnical soil testing.

Make your geotechnical investigation quick and efficient with quality components like the automatic drop hammer and combo head along with tooling systems like the interlocking split spoon. With enough engineering to keep drillers out of harms way, fewer moving parts and loads of tooling storage make your geotechnical investigation safer. Making field operations simpler includes little touches like a measuring device on the drop hammer and indicator arrows to guide the sliding of the head. These all combine for increased productivity.

With efficient and effective versatility to complete SPT, DPT or CPT, complete your geotechnical investigations and expand opportunities for handling multiple types of job sites or offering more service lines to increase your profit potential.

With drill rig service shops in North Carolina, Pennsylvania, Florida, and Kansas, you’ll have service support nearby for your routine maintenance or more in-depth drill rig remounting and refurbishment work. Our service technicians are backed by our team of engineers to ensure solutions not bandaids to issues. And our production processes mean your geotechnical drilling rigs are constructed consistently and tested thoroughly to ensure easier service support.
