Exploration, Environmental & Geotechnical Drilling

World Class Exploration, Environmental and Geotechnical Drilling Services

USK Group is the preferred drilling contractor for major multinational mining companies, engineering and environmental firms.  
We offer world class mineral exploration, environmental drilling and geotechnical drilling investigation services. Using advanced intrusive technologies; our highly-trained drill crews place a strong emphasis on safety, project management, and quality control. We operate in urban areas, in rough terrain, in open fields or inside buildings. 
We have a variety of equipment and experience to get the job done safely, efficiently, on time, and on budget. We specialize in the installation and development of monitoring wells, soil and groundwater sampling and the installation of remediation systems. We operate Sonic, Air and Mud rotary, Auger and Direct push drills of all sizes including short masted, low overhead, rubber track and tire equipment. We conduct soil and groundwater sampling, soil gas sampling, and perform in-situ remediation injections with direct push, auger and sonic rigs. We also have extensive over water barge drilling experience with auger and probe.
We have developed specialized, self-contained decontamination trailers to contain Investigation Derived Waste decontamination water. Decon water can be quickly transferred to drums or a site remediation system prior to demobilization. Pressure washers and steam cleaners are standard equipment on all of our decon trailers and direct push rig support equipment.
All our drilling rigs are equipped with cages to protect personnel from injuries from rotating parts, and are also equipped with specialized dust control measures.
