We have our own drill rigs to get the work done.
SK Geotechnical has three fully equipped drill rigs making us the largest hollow-stem auger drilling company in Montana. We provide dependable, competitive geotechnical and environmental drilling services. Drilling services are provided throughout Montana, Wyoming, South Dakota, Oregon, Washington, North Dakota, and Idaho.
This drill rig is our powerhouse! With over 18,000 foot-pounds of torque, the D-120 is one of the largest, privately owned, hollow-stem drill rigs in Montana. More torque allows us to drill deeper, faster, and provide more detailed subsurface soil, bedrock, and groundwater information for the project.
Have a site with difficult access? Our Mobile B57 is fitted with 24-inch wide rubber tracks, making it capable of traversing 1:1 slopes allowing it to exert a ground pressure of only 6 pounds per square inch! This allows our team to navigate the rig via remote to areas that would otherwise require cutting in and creating temporary access roads, saving you time and money.
CME 75 High Torque
Our CME 75HT rig is our workhorse. Light and lean, this rig is perfect for work with limited turning radii that our D-120 might have difficulty getting to. Don’t let its size fool you though, this dependable rig will help our team get your job done!
