Geotechnical DrillingGeotechnical drilling are performed by geotechnical, civil, or geological engineers to retrieve information on physical properties of soil, foundation, and rock around the area. This generally would be in preparation of building engineering, foundation construction, or even in cases of testing and repairing existing structures.
In mining and natural resources, geotechnical studies typically would involve principles of soil mechanics and rock mechanics to investigate subsurface condition of materials (often with drilling), determine physical properties of the materials, evaluate stability of natural slopes and man-made soil deposits and structures, and monitor site/foundation stability.
Other uses of geotechnical drilling are to measure thermal resistivity of soil for underground transmission lines, oil/gas lines, solar/thermal storage facilities, etc.
A smaller rig amongst the Energold fleet for geotechnical drilling would be the B61.
B61 Auger Rigs are used to perform geotechnical drilling, and are capable of operation in all types of rough terrain - sand, mud, muskeg, swamp, and snow. B61 Auger Rigs have deeper sampling capacities than smaller drills. Drilling depths of 150'-200' are possible with 4 1/4" hollow stem or 6" solid stem.
Larger applications and projects would involve Energold-Dando's Geotec 40 or 60, with a pullback capacity of 60 plus metric tonnes.
