Diedrich D-50

The Diedrich Drill D-50 is a heavy-duty drill rig for soil and rock exploration for both geotechnical and environmental investigations using augers or core drilling tools. The D-50 is rated to depths of 125 feet (38m) to 250 feet (76m) with hollow stem or continuous flight augers up to 14 in (356mm) hole size. It is rated to 1000 linear feet (305m) of core drilling using N series tools. The Diedrich D-50 is comparable in size and ability to a CME-55.

Diedrich D-50 Track

Geoprobe 7822DT

The 7822DT is track-mounted, highly maneuverable (remote controlled) and is capable of drilling on a variety of surfaces, terrains, and in locations not readily accessible to truck-mounted drilling equipment. This rig is perfect for limited access and low clearance areas. Don't be fooled by the size, this drilling rig can spin hollow-stem augers like the big boys! The winch and mast also allow for extra safety measures when drilling. All of these components equal a drilling machine that can take on many unique field applications.

Geoprobe 6600

The Diedrich D-50 Track Rig is a true all-purpose rig. With 9,100 foot pounds of spindle torque, it can muscle through just about any job. Auger, air rotary, or Geoprobe-type drilling will be no problem for this rig. This rig has the same capabilities as our truck D-50 rig, but on a all-terrain track system! The D-50 track only produces 4 PSI of ground pressure. If you need big rig work in a remote location - this is the rig for you!

The Geoprobe 6600 has been a staple in the environmental industry for over two decades. This direct push rig can service many different types of jobs, and is a perfect solution for low clearance or small work areas.

Stanley Dolly Probe

The Stanley Dolly Probe is perfect for shallow probe borings in very hard to reach places. The dolly and associated power-pack can be easily maneuvered in buildings for sub-slab sampling.

Geoprobe 6620DT

The Geoprobe 6620DT is a rubber track-mounted, mobile remote controlled drill rig equipped with a powerful hydraulic hammer with built in rotary spindle that is great for your hard to reach locations!
