Environmental Drilling Rigs by Geoprobe®

Direct Push, Rotary, or Sonic for Subsurface Sampling Success

Complete your environmental investigation faster, easier, and safer – and with less mess – when using a Geoprobe® environmental drill rig.

Make your environmental investigations quick and efficient with quality environmental drill rig components along with tooling systems like the Macro-Core®. With enough engineering to keep drillers out of harms way, fewer moving parts, and loads of tooling storage make your environmental investigations safer. Making field operations simpler includes little touches like modular design or indicator arrows to guide the sliding of the environmental drill rig head. These all combine for increased productivity.

With efficient and effective versatility to complete a range of environmental investigations, expand opportunities for handling multiple geographies or offering more services to increase your profit potential.
